The photon-photon\, photon-hadron and hadron-hadron part relies on a new v ersion of the PHOJET Monte Carlo\, that has been recently updated with new parton densities\, the support for various baryon and meson projectiles a nd retuned parameters taking into account data from the LHC. DPMJET-III ex tends the phenomenology of PHOJET using a Glauber approach and intra-nucle ar cascade phenomenology for nuclear targets. In this talk I will (re-)int roduce the main ingredients\, show recent calculations and discuss remaini ng short-comings of this code.\n\nhttps://indico.nucleares.unam.mx/event/1 100/session/3/contribution/59 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/59 END:VEVENT BEGIN:VEVENT SUMMARY:Multiparton interactions in QGSJET-II DTSTART;VALUE=DATE-TIME:20161129T174000Z DTEND;VALUE=DATE-TIME:20161129T180000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-1-45@cern.ch DESCRIPTION:Speakers: Dr. OSTAPCHENKO\, Sergey (FIAS)\nI'll discuss the tr eatment of multiparton interactions in the framework of the QGSJET-II mode l. A particular attention will be paid to the assumptions concerning the m omentum structure of constituent parton Fock states in hadrons and to the respective consequences for the predicted spectra of secondary hadrons.

Since the last release\, which\ndates back to the TeVatron era\, modeling of hadronic interactions has\nseen development in several d irections. For one the high energy\nfrontier has been significantly moved up by the LHC\, revealing\ndiscrepancies in the prediction of the total cr oss section\, the role\nof multi parton interactions and overall particle production. At the\nsame time the apparent deficit of muons in cosmic ray air shower\nsimulations with regard to observations\, revealed the\nmisrep resentation of hadronic particle production in the\nmodel. Finally the mea surement of high energy neutrinos by the IceCube\nexperiment add the promp t production of neutrinos through charmed\ndecays as a necessary feature o f cosmic ray interaction models.\n\nhttps://indico.nucleares.unam.mx/event /1100/session/3/contribution/57 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/57 END:VEVENT BEGIN:VEVENT SUMMARY:Soft interactions in Herwig DTSTART;VALUE=DATE-TIME:20161129T184000Z DTEND;VALUE=DATE-TIME:20161129T190000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-1-29@cern.ch DESCRIPTION:Speakers: GIESEKE\, Stefan (KIT)\nWe discuss soft interactions as part of the Multiple Partonic\nInteraction model in the Monte Carlo ev ent generator Herwig. The model\nfor soft interactions has been updated a nd complemented with a model for\ndiffractive final states.

This requires experimental data to cons train and tune\nthe models\, and to ultimately gain insights in the underl ying physics.\n\nA Large Ion Collider Experiment (ALICE) at the LHC provid es tracking\ndown to low transverse momenta and excellent particle\nidenti fication. This allows us to perform measurements which are\nwell-suited to constrain the existing Monte Carlo models in the\nnon-perturbative region s of QCD. Our measurements extend over\ndifferent collision systems (pp\, p-Pb\, Pb-Pb) and different collision\nenergies. We will discuss the relev ance of these measurements for\nMonte Carlo comparison and tuning\, foremo st for pp collisions. In\naddition\, we will outline ideas to extend the s ystematic Monte Carlo\ncomparisons to heavy-ion analyses.\n\nhttps://indic o.nucleares.unam.mx/event/1100/session/3/contribution/58 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/58 END:VEVENT BEGIN:VEVENT SUMMARY:Tuning Monte Carlo generators with LHCb results DTSTART;VALUE=DATE-TIME:20161129T155000Z DTEND;VALUE=DATE-TIME:20161129T161000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-0-42@cern.ch DESCRIPTION:Speakers: Dr. ADINOLFI\, Marco (University of Bristol)\nThe we alth of data collected by LHCb during Run~I has allowed obtaining a wide s election of results in the unique phase space covered by its detector: pse udorapidity ($\\eta$) range $2\n\nhttps://indico.nucleares.unam.mx/event/1 100/session/3/contribution/42 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/42 END:VEVENT BEGIN:VEVENT SUMMARY:Monte Carlo tuning for Multiple Parton Interactions from the ATLAS data DTSTART;VALUE=DATE-TIME:20161129T161000Z DTEND;VALUE=DATE-TIME:20161129T163000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-0-8@cern.ch DESCRIPTION:Speakers: CAIRO\, Valentina Maria (Università della Calabria) \nThe modelling of Minimum Bias (MB) and Underlying Event (UE) is a crucia l component in the description of soft\nQCD processes.

It is success ful in the description of particle spectra as well as flow-like observable s and includes viscous hydrodynamics expansion\, hadronic cascade\, and he avy quark production. \n\nIn the beginning\, we will present the general f eatures of the model and show that multiple interactions play a central ro le for both flow-like and particle spectra.\n\nThen\, we will focus on the more specific case of heavy quark production and the study of the dynamic s of high multiplicity pp events.\n\nhttps://indico.nucleares.unam.mx/even t/1100/session/3/contribution/17 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/17 END:VEVENT BEGIN:VEVENT SUMMARY:WG2: Conclusions/Summary DTSTART;VALUE=DATE-TIME:20161202T150000Z DTEND;VALUE=DATE-TIME:20161202T154000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-event-3-2@cern.ch DESCRIPTION:https://indico.nucleares.unam.mx/event/1100/session/3/?slotId= 2 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/?slotId=2 END:VEVENT BEGIN:VEVENT SUMMARY:The forward-backward long-range multiplicity correlations in proto n-proton collisions at LHC energies DTSTART;VALUE=DATE-TIME:20161201T173000Z DTEND;VALUE=DATE-TIME:20161201T175000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-4-1@cern.ch DESCRIPTION:Speakers: Mr. DOMINGUEZ ROSAS\, Edgar (Instituto de Ciencias N ucleares)\nThe forward-backward multiplicity correlations are important fo r the overall event characterization and to extract information on non-per tubative hadronic processes. In this work we present a study of this corre lations based on p+p collisions generated with PYTHIA event generator at L HC energies with different initial conditions of the events to show how it is related with the hadronization mechanism\, as well as to multiple p artonic interactions and consequently the degree of hardness of the collis ions. The effect of the QCD color reconnection strength is presented for m inimum bias and jetty-like events\, demonstrating the possibility to use t hese correlations to investigate underlying events. Finally\, the comparis on with available data suggests that forward-backward multiplicity correla tions could be useful tools to disentangle phenomena in QCD processes.\n\n https://indico.nucleares.unam.mx/event/1100/session/3/contribution/1 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/1 END:VEVENT BEGIN:VEVENT SUMMARY:Looking for more evidence of collective effects in small systems.

Evidence of flow-like patterns has been found in p-p collisions expe rimentally. Based on this results the proposal to use hydrodynamics to des cribe small systems\, like in A-A collisions\, looks tempting\, but\, some other mechanisms\, among them prominently\, Color Reconnection (CR)\, has shown collective effects without invoking hydrodynamics. In this work we present a comparison between EPOS 3 and PYTHIA 8 p-p collisions at \\sqrt{ s} = 7TeV\, two event-generators that use hydro and CR\, respectively. Com puting p_{T} spectra in multiplicity bins\, we are able to extract informa tion of flow-like behaviors.\n\nhttps://indico.nucleares.unam.mx/event/110 0/session/3/contribution/53 LOCATION:Hotel Rincón del Arco Salón Giralda URL:https://indico.nucleares.unam.mx/event/1100/session/3/contribution/53 END:VEVENT BEGIN:VEVENT SUMMARY:Bulk observables in small colliding systems combining CGC and PYTH IA DTSTART;VALUE=DATE-TIME:20161129T210000Z DTEND;VALUE=DATE-TIME:20161129T212000Z DTSTAMP;VALUE=DATE-TIME:20260413T145546Z UID:indico-contribution-3-6-5@cern.ch DESCRIPTION:Speakers: TRIBEDY\, Prithwish (Brookhaven National Laboratory) \nWe combine the IP-Glasma model of Color Glass Condensate with PYTHIA to study bulk observables in small colliding systems at LHC. This framework c ombines the Classical Yang-Mills dynamics of multi-gluon productions and a scheme of fragmentation based on Lund string model for the production of hadrons. In particular we study the high multiplicity events in which obse rvations are often attributed to final state collective effects. We find t hat descriptions based on purely initial state dynamics can be obtained i n our framework for a number of observables like two particle ridge-like c orrelations\, the particle mass dependence of p_T and v_2 (p_T).\n\nRef:\n \n\n\n[1] B.
