Di-hadron
correlations in 3+1D hydrodynamics, the relativistic lattice boltzmann
method and GPU computing
Longgang Pang (Institute
of Particle Physics, Wuhan)
HIJING + ZPC (Zhang Bin's Parton Cascade)
in the AMPT (A Multi Phase Transport) are used to generate fluctuating
initial conditions for (3+1)D event-by-event ideal hydrodynamic
simulations. With longitudinal fluctuations and intrinsic correlations
from mini-jet partons and string fragments, we studied two dimensional
di-hadron correlation $C_{12}( \Delta\eta, \Delta\phi)$ as a function of
azimuthal angle and pseudo-rapidity difference. The study shows that the
per-trigger particle pairs for charged hadrons at low transverse momentum
at the LHC and RHIC can be described by event-by-event hydrodynamic
simulations semi-quantitatively. It is observed that the relative height
of the near side peak in per-trigger particle pairs is strongly correlated
to the collectivity of the expanding fireball. I will also give an
introduction to the recent progress in Relativistic Lattice Boltzmann
Method for (3+1)D viscous hydro with a general EOS, and our recent effort
on applying GPU parallel computing techniques to hydro and jet physics in
Wuhan.
