夸克的横向性分布与核子张量荷

Quark Transversity Distribution and Nucleon’s Tensor Charge

  • 摘要: 夸克的横向性分布的一次矩定义了核子张量荷. 核子张量荷也可用张量流算符在核子态的矩阵元定义,由此用量子色动力学求和规则、有效理论和模型计算了核子张量荷. 对研究核子性质及强子物理的自洽非微扰途径问题也作了简要讨论. The first moment of quark transversity distribution defines the tensor charge of nucleon. The tensor charge of nucleon can also be defined as the forward matrix element of the tensor current in the nucleon state,which is used to study the nucleon’s tensor charge in terms of quantum color dynamics(QCD) sum rule approach, the effective theory and model. A consistent nonperturbative approach to study nucleon property and hadronic physics is also discussed.
