作为夸克质量实验探针的激发重子

Excited baryons as experimental probes of the quark mass

Felipe J. Llanes-Estrada, Pedro Bicudo, Marco Cardoso, Tim Van Cauteren

摘要:

我们观察到,激发强子提供了一个机会,从实验中探测夸克质量在中红外的幂律运行,而条件m(k)<k仍然有效。一个相对干净的分析是可能的最大自旋激发的δ重子,类似于在核中的yrast状态。这些状态可以在当前的实验设施,如ELSA和Jlab中访问。

英文摘要:

We observe that excited hadrons provide an opportunity to probe from experiment the power-law running of the quark mass in the mid infrared, while the condition m(k)<k remains valid. A relatively clean analysis is possible for the maximum spin excitations of the Delta baryons, analogous to the yrast states in nuclei. Such states are accessible at current experimental facilities such as ELSA and Jlab.
