Query: Simulation study of elliptic flow of charged hadrons produced in Au + Au
  collisions at the Facility for Antiproton and Ion Research   Centrality and system geometry dependence of azimuthal anisotropy of charged
hadrons measured in terms of the elliptic flow parameter are investigated using
Au+Au event samples at incident beam energy $20$A GeV and $40$A GeV generated
by Ultrarelativistic Quantum Molecular Dynamics and A Multiphase Transport
models. The Monte Carlo Glauber model is employed to estimate the eccentricity
of the overlapping zone at an early stage of the collisions. Anisotropies
present both in the particle multiplicity distribution and in the kinetic
radial expansion are examined by using standard statistical and
phenomenological methods. In the context of upcoming Compressed Baryonic Matter
experiment to be held at the Facility for Antiproton and Ion Research, the
present set of simulated results provide us not only with an opportunity to
examine the expected collective behavior of hadronic matter at high baryon
density and moderate temperature environment, but when compared with similar
results obtained from Relativistic Heavy Ion Collider and Large Hadron Collider
experiments, they also allow us to investigate how anisotropy of hadronic
matter may differ or agree with its low baryon density and high temperature
counterpart.
