论文摘要
我们已经应用了等异分量张量电流来评估$ n（1535）\ rightArrow n $ n $ transition的张量形式，并借助于轻锥QCD总规则法。在数值计算中，已使用核子和张量电流的插值电流的最通用形式，以及$ n（1535）$状态的DAS中的两个不同的输入参数。我们已经获得了$ n（1535）\ rightarrow n $ transition张量形式的值对$ n（1535）$ state的分布幅度的输入参数非常敏感。我们已经获得了$ q^2 $依赖性$ n（1535）\ rightarrow $ transition Tensor形式的形式是由P-Pole Fit功能很好地定义的。
We have applied isovector and isoscalar tensor current to evaluate the tensor form factors of the $ N(1535) \rightarrow N $ transition with the help of the light-cone QCD sum rule method. In numerical computations, have used the most general forms of the interpolating current for the nucleon and the tensor current together with two different sets of the input parameters in the DAs of the $N(1535)$ state. We have obtained that the values of $N(1535) \rightarrow N$ transition tensor form factors very sensitive to the input parameters of the distribution amplitudes of the $N(1535)$ state. We have acquired that the $Q^2$ dependence of $N(1535) \rightarrow$ transition tensor form factors is well defined by a p-pole fit function.
