摘要
Inspired by the recent anomalies on the lepton flavor universalities, we present an investigation of baryonic form factors induced by heavy-to-light tensor currents. With the light-front quark model, we calculate the tensor form factors, and the momentum distributions are accessed with two parametrization forms. Numerical results for the form factors at q2 = 0 are derived and parameters in q2 distributions are obtained through extrapolation. Our results are helpful for the analysis of new physics contributions in the heavy-to-light transition.
