Probing the QCD Critical Point with Higher Moments of Net-proton Multiplicity Distributions
Net-proton Multiplicity Distributions QCD Critical Point
2011/7/21
Higher moments of event-by-event net-proton multiplicity distributions are applied to search for the QCD critical point in the heavy ion collisions. It has been demonstrated that higher moments as wel...
Direct Photon Production in Proton-Nucleus and Nucleus-Nucleus Collisions
direct photons nuclear suppression gluon shadowing
2011/7/21
Prompt photons produced in a hard reaction are not accompanied with any final state interaction, either energy loss or absorption. Therefore, besides the Cronin enhancement at medium transverse moment...
Mach-like emission from nucleon scattering in proton-nucleus reaction
Mach-like emission nucleon scattering proton-nucleus reaction
2011/7/21
The fast-stage nucleon emission of proton-nucleus (pA) reactions from 300A MeV to 1.8A GeV has been investigated using the quantum molecular-dynamics model. It is found that the sideward angular spect...
