    An abnormal production of events with almost equal-sized fragments was theoretically proposed as a signature of spinodal instabilities responsible for nuclear multifragmentation in the Fermi energy domain. On the other hand finite size effects are predicted to strongly reduce this abnormal production. High statistics quasifusion hot nuclei produced in central collisions between Xe and Sn isotopes at 32 and 45 AMeV incident energies have been used to definitively establish, through the experimental measurement of charge correlations, the presence of spinodal instabilities. N/Z influence was also studied.

    Multiplicity dependent distributions of identified particles in pp collisions at 7 TeV within HIJING/ v2.0 model

    V.Topor Pop🇨🇦 · M.Petrovici🇷🇴

    Effects of strong longitudinal color fields (SCF) on the identified (anti)particle transverse momentum () distributions in collision at = 7 TeV are investigated within the framework of the {\small HIJING/BB̄ v2.0} model. The comparison with the experiment is performed in terms of the correlation between mean transverse momentum () and multiplicity (N) of charged particles at central rapidity, as well as the ratios of the distributions to the one corresponding to the minimum bias (MB) pp collisions at the same energy, each of them normalized to the corresponding charged particle density, for high multiplicity \mbox{(HM, N_{ch}>100)} and low multiplicity \mbox{(LM, N_{ch}<100)} class of events. The theoretical calculations show that an increase of the strength of color fields (as characterized by the effective values of the string tension ), from = 2 GeV/fm to = 5 GeV/fm from LM to HM class of events, respectively, lead to a ratio at low and intermediate (i.e., \mbox{GeV/{\it c} GeV/{\it c}}) consistent with recent data obtained at LHC by the ALICE Collaboration.
