基于核子溶胀模型的气味依赖的EMC效应

Flavor-dependent EMC effect from a nucleon swelling model

Rong Wang, Raphaël Dupre, Yin Huang, Baiyang Zhang, Silvia Niccolai

摘要:

基于nIMParton核PDF,我们给出了一个基于味道的EMC效应的结果,其中$x$依赖性用核子溶胀模型描述。本文通过对初始价夸克分布的修正而不是动力学重标度来考虑核子膨胀引起的核修正。为了探索模型的味道依赖性,实验观测值计算应用nIMParton核修改各种实验:宇称破坏核目标上的深度非弹性散射,π介子诱导的Drell-Yan,和W-玻色子生产质子-核碰撞。此外,我们提出了观众标记的深度非弹性散射过程的预期效果,这将由CLAS 12与ALERT探测器合作进行。

英文摘要:

We present our results for a flavor-dependent EMC effect based on the nIMParton nuclear PDFs, in which the $x$-dependence is described with a nucleon swelling model. The nuclear correction from nucleon swelling is considered through a modification of the initial valence quark distributions instead of a dynamical rescaling. To probe the flavor-dependence of the model, the experimental observables are calculated applying nIMParton nuclear modifications for various experiments: parity-violating deep inelastic scattering on nuclear target, pion-induced Drell-Yan, and W-boson production in proton-nucleus collisions. In addition, we present the expected effect for the spectator-tagged deep inelastic scattering process, which will be performed by the CLAS12 collaboration with the ALERT detector.
