Study of $ππ$ correlations at LHC and RHIC energies in $pp$ collisions within the quark-gluon string model
quark-gluon string model RHIC energies
2011/7/21
The Quark Gluon String Model (QGSM) reproduces well the global characteristics of the $pp$ collisions at RHIC and LHC, e.g., the pseudorapidity and transverse momenta distributions at different centra...
Study of the neutron skin thickness of ${}^{208}$Pb in mean field models
mean field models
2011/7/20
We study whether the neutron skin thickness $\Delta r_{np}$ of ${}^{208}$Pb originates from the bulk or from the surface of the neutron and proton density distributions in mean field models.
Stability of fragments and study of participant-spectator matter at peak center-of-mass energy
center-of-mass energy participant-spectator matter
2011/7/20
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...
A Study of the QCD Critical Point Using Particle Ratio Fluctuations
QCD Critical Point Particle Ratio Fluctuations
2011/7/20
Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. Results from new measurements of dynamical $K/\pi$ and $p...
