Measurement of neutral pions in $\sqrt{s_{\mathrm{NN}}}$=200GeV and 62.4GeV Au+Au collisions at RHIC-PHENIX

Abstract

Neutral pions (${\pi }^0$) in $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV and 62.4 GeV Au+Au collisions were measured at RHIC-PHENIX Year-4 Run. In $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV, ${\pi }^0$ specta are measured up to p${}_{\mathrm{T}}$ = 20 GeV/$c$. %PHENIX extended the p${}_{\mathrm{T}}$ region of A strong suppression by a factor of $\sim$ 5 is observed and stays almost constant up to 20 GeV/$c$.
