V0 directed flow study in AuAu@62GeV

Lambda, Anti-Lambda, K0Short directed flow in AuAu@62GeV data was measured by two and three particle correlations (FTPC, ZDCSMD and TPC data were used). In the error range the obtained results are consistent with zero.

Elliptic flow study in AuAu@62GeV

Non-flow contribution

By using the different charged sub-events the significant non-flow contribution from KSI decays were found, both in Lambda and Anti-Lambda elliptic flows. By correlating with event planes from different pseudo-rapidity region (TPC and FTPC event planes) the non-flow contribution to V0 elliptic flow has been estimate.

Barion to anti-barion asymmetry

The barion/anti-barion asymmetry investigated by studying the Lambda to anti-Lambda elliptic flow ratio. The barion to anti-barion elliptic flow ratio is found systematically different from 1 by few percents.
