PHENIX中的带电强子谱

Charged Hadron Spectra in PHENIX

J. Jia

摘要:

PHENIX在sqrt{s}=200 GeV的Au+Au碰撞中测量了中等快度至10 GeV/c的带电粒子的横动量谱。对于中心碰撞,在高pT的产量显着抑制相比,二进制缩放的p+p数据,这种抑制是强于在130 GeV观察到的。在4GeV/c以上,高动量粒子的亏损几乎与pT无关。

英文摘要:

PHENIX has measured transverse momentum spectra of charged particles at mid-rapidity up to 10 GeV/c in Au+Au collisions at sqrt{s}=200 GeV. For central collisions, the yield at high pT is significantly suppressed comparing to binary scaled p+p data, and this suppression is stronger than observed at 130 GeV. Above 4 GeV/c, the deficit of high momentum particles is almost independent of pT.
