Description
We employed the new issue of a parton and hadron cascade model PACIAE 2.1 to systematically investigate the charged particle elliptic flow parameter v2 and eccentricity ε2 in the relativistic Pb-Pb collisions at 2.76 TeV. With randomly sampling the transverse momentum x and y components of the particles generated in string fragmentation on the circumference of an ellipse instead of circle originally in PACIAE 2.0, the calculated charged particle probability density distribution of v2 and ε2 as well as their relative fluctuations reproduce the corresponding ATLAS data well.
