Transverse spectra of hadrons in central AA collisions at RHIC and LHC from pQCD plus saturation plus hydrodynamics and from pQCD plus energy losses

摘要

We study the transverse spectra of hadrons in nearly central AA collisions at RHIC and LHC in a broad transverse momentum range [1]. LOW-PT spectra are calculated by using boost-invariant hydrodynamics with initial energy and net-baryon densities from the EKRT [2] pQCD+saturation model. High-p(T) spectra are obtained from pQCD jet calculation [3] including the energy loss of the parton [4] in the matter prior to ills fragmentation to final hadrons.
