Abstract

Elliptic flow parameter, v2v_{2} is consider as a sensitive probe for early dynamics of the heavy-ion collision. In this work we have discussed the effect of detector efficiency, procedure of centrality determination, effect of resonance decay, procedure to obtain event plane resolution on the measured v2v_{2} by standard event plane method within the framework of a transport model. The measured value of v2v_{2} depends on the detector efficiency in particle number counting. The effect of centrality determination is found to be negligible. The method of event-by-event correction of event plane resolution for wide centrality bin yields in results closer to the true value of v2v_{2}. The effect of resonance decay is seen to decrease the v2v_{2} of π\pi, KK and pp. We also propose a procedure to correct for an event bias effect on v2v_{2} while comparing the minimum bias centrality v2v_{2} values for different multi-strange hadrons. Finally we have presented a model based confirmation of the recently proposed relation between v2v_{2} obtained using event plane method and scalar product method to the true value of v2v_{2}.
