Large transverse momentum suppression of $π^0$'s in Au+Au and d+Au collisions at $\sqrt{s}=200$ GeV

Authors

Description

We propose a model of suppression of $π^0$'s based on two different effects: at low $p_T$ we take into account the shadowing corrections, while at large $p_T$ the suppression is produced due to the interaction of the large $p_T$ pion with the dense medium created in the collision. The main features of the data on $AuAu$ and $dAu$ collisions are reproduced both at mid and at forward rapidities.
