26 Apr 2013 | Abstract: | Net-baryon, net-charge and net-strangeness number fluctuations in high energy
heavy-ion collisions are discussed within the framework of a hadron resonance
gas (HRG) model. Ratios of the conserved number susceptibilities calculated in
HRG are being compared to the corresponding experimental measurements to
extract information about the freeze-out condition and the phase structure of
systems with strong interactions. We emphasize the importance of considering
the actual experimental acceptances in terms of kinematics (pseudorapidity
($eta$) and transverse momentum ($p_{T}$)), the detected charge state and
effect of resonance decays before comparisons are made to the theoretical
calculations. In this work, based on HRG model, we report that the net-baryon
number fluctuations are least affected by experimental acceptances compared to
the net-charge and net-strangeness number fluctuations. | Source: | arXiv, 1304.7133 | Services: | Forum | Review | PDF | Favorites |
