Silicon Photomultipliers (SiPM) attached to plastic organic scintillator make up the primary light sensor in the MiniBeBe (MBB) detector. In this presentation, advances in the Front-End development will be presented. Moreover, an important topic for discussion is the fast output signals interconnection for SiPM arrays and its effects. Finally, the current prototype design and fabrication issues wi

Studies made with the UrQMD and the BeBe detector showed an efficiency below expected in ranges of pseudorapidity near the beam direction, this was the main motivation to use a different transport approach. The Parton-Hadron String Dynamics describes the full evolution of events coming from heavy-ion collisions, with a theoretical description different from the UrQMD. Preliminary results with the

The electromagnetic fields at energies of the MPD-NICA experiment are intense on the order of one Pion mass squared, in units of the international system it is approximately $ 10^{13}$ $T $. In this talk, we present the characterization of electromagnetic fields at the initial moment of the collision at NICA energies, their temporal evolution and considering the electromagnetic fields in UrQMD nat

Nonzero baryon density QCD lattice simulations suffer from the well known sign problem, which has so far prevented the exploration of the QCD phase diagram. In this talk we discuss our results on the phase diagram of the 3d O(4) model. This model is an effective theory of QCD with two flavors in the chiral limit, which can be simulated at nonzero baryon density without sign problem. In this model

In this talk we report on a calculation for particle hadronization after heavy ion collisions using both the Siemens-Rassmusen and the Schnederman-Sollfrank-Heinz freeze-out models. We compare the transverse momentum spectra of pions and protons using these models with RHIC data. Furthermore, we use Therminator generator to simulate Au+Au collisions at 200 GeV, and also we compare with RHIC data.

The system created in semi-central heavy ion collisions behaves like a fluid with a large orbital angular momenta, resulting in a great vorticity. Due the spin-orbit coupling we expect that particles produced in such collisions, acquire polarization in the direction of the orbital angular momenta of the system, and that the induced polarization be the same for particles and antiparticles. However

Multi-Purpose Detector (MPD) is a part of Nuclotron-based Ion Collider fAcility (NICA) located in Dubna, Russia. For full functionality, the MPD needs an additional trigger system for off-beam calibration of MPD sub-detectors and for rejection of cosmic ray particles (mainly muons). The system could also be very useful for astrophysics observations of cosmic showers initiated by high energy primar

The MexNICA collaboration is a consortium formed by researchers and students from five Mexican institutions working within the NICA-MPD. During the last three years we have defined a solid scientific program that includes the design and construction of two detectors: a fast TOF trigger and a beam-monitoring detector. The program also includes exploring signals to characterize the kind of matter fo

Using the linear sigma model coupled to quarks, we discuss the influence of an external magnetic field on the QCD phase diagram in the temperature vs.chemical potential plane. Provided the plasma screening is properly accounted, we show that the critical temperature for the phase transition, chiral symmetry restoration, decrease with increasing magnetic field (inverse magnetic catalysis). The loca

The mechanical structure will be the main support for the active elements and electronics of miniBeBe. Its location and installation will be around the beam tube, in the center of the MPD (Multi-Purpose Detector). For this version, the low-cost requirements were considered, which optimized a lightweight and firm structure. The first structural design approach was made through 3D printing, which al

The location of the ---up to now hypothetical--- critical end point and the exploration of the QCD phase diagram are important challenges both theoretically and experimentally. With two massless quark flavors the QCD Lagrangian has a $SU(2)_L\otimes SU(2)_R \simeq O(4)$ symmetry. This Lagrangian is the same as the four component Heisenberg ferromagnet which we use as an effective model. With degen

The Multi-Purpose Detector (MPD) is at Nuclotron Ion Collider fAcility (NICA) of Joint Institute for Nuclear Research (JINR). An important part of the experiment is the particle identification analysis. The idea is to determine from reconstruction, the particles that interact with each MPD sub-detector. This particle identification (PID) is made using statistical techniques (Bayesian method) from

In this work, the photon production at the early stages of a heavy-ion collision is computed by taking into account the magnetic field effects on a magnetized glasma. In particular, the gluon fusion and gluon splitting channels are considered. The magnetic field effect is given in terms of the internal quark lines through the fermion propagator expressed in Landau levels. Moreover, the dependence

QCD at high chemical potential has interesting properties such as diquark condensation and deconfinement of quarks. Two-colour QCD, which enables numerical simulations on the lattice, constitutes a laboratory to study QCD at high chemical potential.
We studied two colour QCD at high density, using the Nambu-Gorkov formalism, which puts the quarks and antiquarks into a single spinor. We examine

MPD-NICA experiment. It will be located on both sides (+/- 2 meters from IP).

The miniBeBe detector is designed to be a level 0 trigger for the TOF detector in the NICA-MPD. This detector needs to have a fast response to function correctly as a trigger, so it is important to implement it in the MPDRoot Framework and perform simulation studies. In this talk I discuss the capabilities of miniBeBe from the results of our simulations to be a level 0 trigger detector for TOF, be

The polarization of $\Lambda$ hyperons is self-analyzed in their weak decays and represents a sensitive tool to explore the dynamics of hadronic reactions and heavy-ion collisions. It was extensively studied in hadronic reactions, where it is directed along the normal to the scattering plane. In heavy-ion collisions this observable is expected to decrease due to randomization of the scattering on

Experiments that collide heavy nuclei at high energies have proven to be incredibly useful to study matter at its fundamental level. One of the most striking features of matter in heavy-ion collisions is that it forms the most perfect fluid that we know of and, consequently, can be described using the methods of hydrodynamics. Within this framework, the study of the thermal vorticity can lead to
