D^+/D^-产生不对称性的能量依赖性

On the energy dependence of the D^+/D^- production asymmetry

E. R. Cazaroto, V. P. Goncalves, F. S. Navarra, M. Nielsen

摘要:

本文讨论了D介子产生中存在的不对称性的起源及其能量依赖性。特别地,我们应用介子云模型计算了高能p-p碰撞中D^-/D^+介子产生的不对称性,并与最近的LHCb实验数据进行了比较,结果符合得很好。虽然很小,但这种不对称性可能会揭示质子的粲介子云所扮演的角色。

英文摘要:

In this paper we discuss the origin of the asymmetry present in D meson production and its energy dependence. In particular, we have applied the meson cloud model to calculate the asymmetries in D^-/D^+ meson production in high energy p-p collisions and find a good agreement with recent LHCb data. Although small, this non-vanishing asymmetry may shed light on the role played by the charm meson cloud of the proton.
