Description
A hot and dense matter is produced in heavy-ion collisions at
relativistic energies.
Anisotropic expansion of this matter result in the momentum asymmetry
of the particle production relative to the reaction plane, a so called
azimuthal anisotropic flow.
In this poster, the measurement of the elliptic flow for negatively
charged pions in inelastic Pb-Pb collisions at the beam energy of 40
AGeV obtained with the fixed target experiment NA49 at CERN SPS are
presented.
Results are compared with measurements at similar energies by the STAR
experiment at RHIC.
Elliptic flow is measured using the event plane method.
Event plane angle and the negatively charged pions are reconstructed
using particle's tracks and energy loss measurement in the Time
Projection Chamber (TPC).
In the future, these results will be used as a reference for flow
measurements from the lead ion energy scan program of the NA61/SHINE
experiment at CERN SPS.
