We use the linear sigma model coupled to quarks to compute the effective potential beyond the mean field approximation, including the contribution of the plasma screening effects, at finite temperature and density. We determine uniquely the model coupling constants (the only free parameters in the model) and use them to study the phase diagram in the temperature-baryon chemical potential plane...
To understand the origins of collective-like phenomena observed in pp collisions at LHC energies, underlying mechanisms have to be identified. In this context, event shape observables provide a possible tool to disentangle soft and hard contributions to particle production. We report on a study of the production of pions, kaons and protons as a function of transverse spherocity in high...
Identified hadron spectra from recent years are analyzed in the non-extensive thermodynamical framework. The Tsallis cut power-law is known to describe the p T distributions for a wide energy range, but its origin is still unknown. We pursue the physical origin of this observation by investigating the center-of-mass energy, multiplicity, mass and strangeness dependency of the Tsallis q and T...
A study of the universality of multihadron production in nucleus-nucleus and pp/{\bar p}p collisions is performed using the dependencies of the midrapidity pseudorapidity and transverse energy densities and of the mean multiplicity on the collision energy and on the number of nucleon participants, or centrality, in the energy range from a few GeV to a few TeV. The approach in which the...
In this work, we propose a tool to reveal the origin of the collective-like phenomena observed in proton–proton collisions. We exploit the fundamental difference between the underlying mechanisms, color reconnection and hydrodynamics, which produce radial flow patterns in Pythia 8 and Epos 3, respectively. Specifically, we proceed by examining the strength of the coupling between the soft and...
The study of the charged particle production as a function of the multiplicity in small colliding systems, as pp, is an attractive tool to understand the similarities and differences between small and large colliding systems. Evidence of similarities, like coherent and collective effects, well know in AA collisions, has been found experimentally even in small systems.
Recent results of the...
