Isovector and isoscalar tensor form factors of $N\left(1535\right)\to N$ transition in light-cone QCD

2020    Özdem, Ulaş

We have applied isovector and isoscalar tensor current to evaluate the tensor form factors of the $N\left(1535\right)\to N$ 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 distribution amplitudes (DAs) of the $N\left(1535\right)$ state. We have obtained that the values of $N\left(1535\right)\to N$ transition tensor form factors are very sensitive to the input parameters of the DAs of the $N\left(1535\right)$ state. We have acquired that the ${Q}^{2}$ dependence of $N\left(1535\right)\to $ transition tensor form factors is well defined by a $p$-pole fit function.
