用PHENIX测量Jpsi和双电子光产生

Jpsi and dielectron photoproduction measurements with PHENIX

Zaida Conesa del Valle

摘要:

利用PHENIX实验测量了200 GeV超外围Au+Au碰撞中的Jpsi和双电子光生.触发事件对应于那些伴随着从Au解离的正向中子发射。Jpsi和高质量的双电子截面和pT分布与各种理论计算是一致的。

英文摘要:

Jpsi and dielectron photoproduction measurements in ultra-peripheral Au+Au collisions at 200 GeV with the PHENIX experiment are presented. The triggered events correspond to those accompanied with forward neutron emission from the Au dissociation. Jpsi and high-mass dielectron cross sections and pT distributions are consistent with various theoretical calculations.
