Since then\, a significant number of new experiments are planned to obs erve this elusive process using different nuclei.\n\nIn this talk\, we wil l discuss the Standard Model physics that can be\nextracted from this proc ess\, along with some searches of New Physics\nthat have been extensively studied\, such as the so called Nonstandard\nNeutrino Interactions (NSI). To explain NSI\, we have proposed a model\nwith a new light gauge Z' boson that couples differently with each\nflavor. In order to constrain this mo del\, we used COHERENT\ndata\, as well as future upgrades consisting of LA r\, Ge\, and NaI\ndetectors. We found that this model leads to four differ ent\nphenomenological viable scenarios\, with different predictions in the \nneutrino sector as well as different cross sections for CEvNS.\n\nhttps: //indico.nucleares.unam.mx/event/1546/session/4/contribution/151 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/4/contribution/151 END:VEVENT BEGIN:VEVENT SUMMARY:The Pc(4312) exotic DTSTART;VALUE=DATE-TIME:20200710T144500Z DTEND;VALUE=DATE-TIME:20200710T150200Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-150@cern.ch DESCRIPTION:Speakers: Dr. FERNANDEZ RAMIREZ\, Cesar (ICN-UNAM)\nThe recent ly discovered pentaquark signal $P_c(4312)^+$ by the LHCb collaboration la ys right below the $\\Sigma_c^+ \\bar{D}^0$ threshold\, making it a prime candidate for a molecular interpretation.

Thus\, it is possible to achieve better measurements by extending the range of directions in whi ch the production of particles (or their absence) can be detected. The stu dy of diffractive events with ALICE experiment of the Large Hadron Collide r (LHC) in proton-proton (pp)\, lead-lead (Pb-Pb)\, and proton-lead (p-Pb) collisions could improve its efficiency with the installation of the FDD (Fast Interaction Trigger Diffractive) detector for Run-3\, since such det ector will increase the time resolution compared to AD (ALICE diffractive) detector used in Run-2. The proposal of this work is the initial developm ent of a control system (DCS\, Detector Control System) for the new FDD de tector and its integration in the ALICE experiment\, according to the rule s of the new Online-Offline (O2) infrastructure for Run-3 of the LHC\, by using the SCADA system (Supervisory Control and Data Acquisition) called W inCC-OA. This proposal will allow the DCS of FDD detector to have an optim al performance in the physical data acquisition runs\, mainly. This perfor mance can be quantitatively assessed by estimating and comparing the param eters such as: number and duration of runs\, Data Taking Efficiency (DTE)\ , End Of Runs (EOR) and Pause And Reconfiguration (PAR)\; with respect to the other detectors and systems of the experiment.\n\nhttps://indico.nucle ares.unam.mx/event/1546/session/2/contribution/171 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/2/contribution/171 END:VEVENT BEGIN:VEVENT SUMMARY:Tau Physics at Belle II DTSTART;VALUE=DATE-TIME:20200709T165000Z DTEND;VALUE=DATE-TIME:20200709T170700Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-170@cern.ch DESCRIPTION:Speakers: Ms. GARCÍA HERNÁNDEZ\, Marcela (CINVESTAV)\nThe Su perKEKB collider has recently achieved an instantaneous luminosity of 2.22 x 10^34 cm-2 s-1\, the world's highest\, and will increase up to 8 x 10^3 5 cm-2 s-1 in the next few years.\nIt collides electrons and positrons at the Belle II experiment at a center-of-mass energy of the Upsilon(4S) mass . Belle II is not only a considered a Super B-factory\, but also a tau-fac tory.

In the ordinary theory\, the electromagnetic coupling needs to exc eed a critical value in order for mases to be generated. Adding the influe nce of a Chern-Simons term\, it is observed that there exists a critical v alue of the theta-term above which chiral symmetry is restored regardless the strength of the coupling. These findings are of direct relevance in gr aphene physics to understand the semimetal-insulator transition in the pre sence of parallel electric and magnetic fields.

These were formerly thought to be achievable only in heavy-ion collisions. To understand the origins of these unexpected phenomena\, eve nt shape observables such as transverse spherocity ($S_{\\rm{0}}$) and the relative transverse activity classifier ($R_{\\rm{T}}$) can be exploited as a powerful tool to disentangle soft and hard particle production.\n\nRe sults on the production of light flavor hadrons ($\\pi$\, K p\, $\\Phi$ an d $\\Xi$) as a function of $S_{\\rm{0}}$ and $R_{\\rm{T}}$ in high multipl icity pp collisions at $\\sqrt{s}$ = 13 $\\textrm{TeV}$ measured with the ALICE detector at the LHC are presented. The evolution of particle ratios and average transverse momentum ($\\langle p_{\\rm T}\\rangle$) with multi plicity\, $S_{\\rm{0}}$ and $R_{\\rm{T}}$ is also discussed in the context of radial flow and flow-like effects. In addition\, the system size depen dence of charged particle production in pp\, p-Pb and Pb-Pb collisions at $\\sqrt{s}$ = 5.02 TeV will be presented. The evolution of the transverse momentum spectra\, integrated yields and average $p_{\\rm T}$ in the near and away sides as a function of $R_{\\rm{T}}$ are presented and compared w ith event generators such as EPOS-LHC and PYTHIA8 (ANGANTYR). Within this approach\, we perform jet quenching searches in small collision systems.\n \nhttps://indico.nucleares.unam.mx/event/1546/session/10/contribution/145 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/10/contribution/14 5 END:VEVENT BEGIN:VEVENT SUMMARY:HEP Perspectives from the theory side after LHC DTSTART;VALUE=DATE-TIME:20200710T200000Z DTEND;VALUE=DATE-TIME:20200710T204000Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-142@cern.ch DESCRIPTION:Speakers: Dr. DIAZ-CRUZ\, Lorenzo (FCFM-BUAP)\, Dr. DIAZ-CRUZ\ , Lorenzo (Benemerita Universidad Autonoma de Puebla)\, Prof. DIAZ-CRUZ\, Lorenzo (FCFM-BUAP)\nhttps://indico.nucleares.unam.mx/event/1546/session/6 /contribution/142 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/6/contribution/142 END:VEVENT BEGIN:VEVENT SUMMARY:Flavor Symmetry from String Theory DTSTART;VALUE=DATE-TIME:20200710T194000Z DTEND;VALUE=DATE-TIME:20200710T195700Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-148@cern.ch DESCRIPTION:Speakers: BAUR\, Alexander (Tecnical University of Munich & \; Nacional Autonomous University of Mexico)\nFlavor symmetry might play a crucial role in the standard model of particle physics\, but its origin i s still unknown. We consider a string theory-based scenario\, in which the flavor symmetry arises from the compactification of extra dimensions. We observe that compactifications on toroidal orbifolds yield naturally discr ete flavor symmetries that consist of traditional flavor symmetries as wel l as modular symmetries\, combined in a so-called "eclectic flavor group". Consequently\, a remarkable feature arises: the unified flavor symmetry d epends on the position in moduli-space.\n\nhttps://indico.nucleares.unam.m x/event/1546/session/6/contribution/148 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/6/contribution/148 END:VEVENT BEGIN:VEVENT SUMMARY:Anomalous coupling studies with forward protions at the LHC DTSTART;VALUE=DATE-TIME:20200710T165000Z DTEND;VALUE=DATE-TIME:20200710T170700Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-120@cern.ch DESCRIPTION:Speakers: Prof. ROYON\, Christophe (University of Kansas)\nWe will discuss the sensitivities at the LHC to quartic anomalous couplings.

(Benemerita Universidad Aut onoma de Puebla\, Mexico)\nThe necessity for both higher precision and rat es in high-energy physics (HEP) has advanced research and development conc erning precise time and position measurements from a variety of detectors. Thanks to their excellent time accuracy\, Multigap Resistive Plate Chambe rs (MRPCs) are often used as time-of-flight (TOF) detectors in HEP and nuc lear experiments.\nIn previous studies\, a time resolution of 25 ps was ob tained from a 20-gap MRPC with a 140 $\\mu$m gap size and enhanced rate ca pability. In this work we consider a 10-gap MRPC with 160 $\\mu$m gaps. Th is MRPC uses a new type of commercially available thin low-resistivity gla ss which further improves the rate capability. Tests were performed at the continuous electron beam at ELBE. This 10-gap MRPC reaches 97% efficiency at 19.2 kV with a time resolution of 36 ps at particle fluxes near 2 kHz/ $cm^{2}$. At a flux of 100 kHz/$cm^{2}$\, the efficiency is still above 95 % and a time resolution of 50 ps is obtained. The broad hit rate capabili ties of these MRPCs fulfill the requirements for their use in future exper iments and for ultra high rate applications.\n\nhttps://indico.nucleares.u nam.mx/event/1546/session/10/contribution/168 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/10/contribution/16 8 END:VEVENT BEGIN:VEVENT SUMMARY:Tau physics DTSTART;VALUE=DATE-TIME:20200709T160500Z DTEND;VALUE=DATE-TIME:20200709T164500Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-126@cern.ch DESCRIPTION:Speakers: GONZÀLEZ-SOLÍS\, Sergi ()\nhttps://indico.nucleare s.unam.mx/event/1546/session/5/contribution/126 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/5/contribution/126 END:VEVENT BEGIN:VEVENT SUMMARY:Potential of MATHUSLA for cosmic ray research DTSTART;VALUE=DATE-TIME:20200709T150500Z DTEND;VALUE=DATE-TIME:20200709T152200Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-164@cern.ch DESCRIPTION:Speakers: Dr. ARTEAGA VELAZQUEZ\, Juan Carlos (Instituto de F ísica y Matemáticas\, Universidad Michoacana)\nThe main objective behind the MATHUSLA proposal is to build a large area hodoscope detector at grou nd level\, close to the interaction point of the CMS detector\, to look f or the decay signals of neutral long lived particles (LLP) at the next HL- LHC runs in an environment with low background. LLPs are expected in the c ontext of Beyond Standard Models\, which try to solve open problems in fun damental particle physics. The idea behind MATHUSLA is to monitor a large volume of air (100 m x 100 m x 25 m) with a series of layers of tracking detectors to look for displayed vertices produced by the LLPs. The updated MATHUSLA design considers extruded scintillators for the tracking detecto rs. However\, it has been also considered to add an extra layer of RPCs to enhance the extensive air shower detection capabilities of MATHUSLA to c arry out cosmic ray studies in the 100 TeV - 100 PeV regime. In this talk\ , a brief introduction to MATHUSLA will be presented\, with an emphasis on its sensitivity to cosmic ray detection.

In this talk\, we are also going to expose recent studies to extent the ionization efficienc y for Si to lower energies\, reaching the region of interest for dark matt er and neutrino searches.  \n\nhttps://indico.nucleares.unam.mx/event/154 6/session/5/contribution/161 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/5/contribution/161 END:VEVENT BEGIN:VEVENT SUMMARY:Current and future constraints on sterile neutrinos from Cevns DTSTART;VALUE=DATE-TIME:20200709T204500Z DTEND;VALUE=DATE-TIME:20200709T210200Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-162@cern.ch DESCRIPTION:Speakers: Mr. SANDERS\, Oscar (Departamento de Física\, CINVE STAV)\nCoherent elastic neutrino-nucleus scattering (Cevns) is a process t hat\nhad been predicted since the 70's and has been recently measured in\n two different detectors by the COHERENT collaboration. In this talk I\nwi ll concentrate in the implications of these results on sterile\nneutrinos. I will also discuss future perspectives in this lively\nfield. Implicatio ns for other tests of the Standard Model\, such as a\nmeasurement of the w eak mixing angle will be briefly discussed.\n\nhttps://indico.nucleares.un am.mx/event/1546/session/4/contribution/162 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/4/contribution/162 END:VEVENT BEGIN:VEVENT SUMMARY:Production studies on heavy quarkonium in pp collisions at 13 TeV DTSTART;VALUE=DATE-TIME:20200710T152500Z DTEND;VALUE=DATE-TIME:20200710T154200Z DTSTAMP;VALUE=DATE-TIME:20260614T230556Z UID:indico-contribution-1546-115@cern.ch DESCRIPTION:Speakers: JHOVANNY\, Mejia (Universidad de Antioquia)\nWith th e increased center-of-mass energy and luminosity at the LHC\, the studies of the heavy\nquarkonium systems like Bc(1S) has been renewed. CMS has rec ently reported the observation\nof two very well separated peaks\, interpr eted as the predicted Bc(2S) and Bc(2S)* states\,\nwhen studying the mass distribution of the Bcππ system. \nWith the full Run-II data\, correspon ding to an integrated luminosity of 143 fb^{-1} of pp interactions\, \nIn this talk we report the studies performed on those selected candidates to extract the\nproduction ratios and other characteristics.\n\nhttps://indic o.nucleares.unam.mx/event/1546/session/7/contribution/115 LOCATION:Mexico City Virtual URL:https://indico.nucleares.unam.mx/event/1546/session/7/contribution/115 END:VEVENT END:VCALENDAR
