Abstract

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.

Highlights

  • The essential subject of QCD is to understand the internal structure of hadrons and their features in terms of degrees of freedom of quark gluons

  • Inspired by the future experiments at Jefferson Laboratory (JLab), we aim to investigate the isovector and isoscalar tensor form factor Nð1535Þ → N transition up to a momentum transfer of Q2 ≤ 10 GeV2 with the help of the light-cone QCD sum rule

  • II, we present the details of our light-cone QCD sum rule calculations

We have applied isovector and isoscalar tensor current to evaluate the tensor form factors of the Nð1535Þ → 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 Nð1535Þ state. We have obtained that the values of Nð1535Þ → N transition tensor form factors are very sensitive to the input parameters of the DAs of the Nð1535Þ state. We have acquired that the Q2 dependence of Nð1535Þ → transition tensor form factors is well defined by a p-pole fit function
