Effects of elliptic flow and resonance decay process on the Kurtosis of net baryon distributions

Kurtosis is regarded as a meaningful and promising observable in searching for the possible critical point predicted by QCD. In this paper, the effects of elliptic flow and resonance decay process on the Kurtosis have been studied with Monte Carlo event generators in Au+Au collisions at √SNN=200 GeV. The results show that the Kurtosis is not sensitive to elliptic flow and resonance decay process.
