Description
We systematically compute the Λb(p,sb)→Λc(2595)+ and Λb(p,sb)→Λc(2625)+ form factors within the heavy quark effective theory (HQET) framework including O(1/m^c_2) contributions. Besides taking into account the Standard Model–like vector and axial contributions, we further determine tensor and pseudotensor form factors. Our work constitutes a step forward with respect to previous analyses allowing for a comprehensive study of the matrix element parametrization stemming from the HQET formalism. Finally, we demonstrate that the resulting form factors are in agreement well with lattice quantum chromodynamics (LQCD) determinations. We show that the newly derived 1/m_c^2 corrections are necessary to reconcile LQCD results with HQET computations.
