在CERN大型强子对撞机上强子-强子和核-核碰撞中光矢量介子的光生

Light vector meson photoproduction in hadron-hadron and nucleus-nucleus collisions at the energies available at the CERN Large Hadron Collider

G. Sampaio dos Santos, M. V. T. Machado

摘要:

在这项工作中,我们使用色偶极方法分析了在LHC能量下相干pp、pA和AA碰撞中光生光矢量介子预测的理论不确定性。特别是,我们提出了我们的预测的rh 0和phi光生快度分布和矢量介子波函数和偶极截面的唯象模型的选择相关的不确定性进行分析。比较最近ALICE分析在2.76 TeV的PbPb碰撞的相干生产ρ。

英文摘要:

In this work we analyse the theoretical uncertainties on the predictions for the photoproduction of light vector mesons in coherent pp, pA and AA collisions at the LHC energies using the color dipole approach. In particular, we present our predictions for the rapidity distribution for rh0 and phi photoproduction and perform an analysis on the uncertainties associated to the choice of vector meson wavefunctionand the phenomenological models for the dipole cross section. Comparison is done with the recent ALICE analysis on coherent production of rho at 2.76 TeV in PbPb collisions.
