ALICE的衍射和超周边碰撞
Diffraction and ultraperipheral collisions at ALICE
摘要：
ALICE实验测量了sqrt（sNN）= 2.76TeV的Pb+Pb超周边碰撞在正向和中心快度下的J/psi光生.相干J/psi截面被发现与那些模型，其中包括核胶子阴影符合EPS 09参数化的协议。本文还简要讨论了Pb+Pb超周边碰撞中rho_0光生的结果。本文还介绍了p+Pb碰撞中的J/psi排斥和pp碰撞中的衍射研究。
英文摘要：
The ALICE experiment measured J/psi photoproduction in Pb+Pb ultraperipheral collisions at sqrt(s_NN) = 2.76 TeV at forward and central rapidity. The coherent J/psi cross section is found to be in good agreement with those models which include nuclear gluon shadowing consistent with EPS09 parametrization. Results on rho_0 photoproduction in ultra-peripheral Pb+Pb collisions are also briefly discussed. Studies on exclusive J/psi in p+Pb and on diffraction in pp collisions are mentioned.
