Analysis of the B(S) → T(jp=2-) Transition in Light Cone Qcd Sum Rules

Abstract

The semileptonic B(s) → T(JP=2-)l+l- decays induced by flavor changing neural currents are investigated within the light cone quantum chromodynamics (QCD) sum rule method in the leading order of O(αs). We apply the B meson distribution amplitudes up to twist-4 and calculate the relevant form factors of the B(s)→T transitions, where T=K2,a2,f2,φ2 with JP=2-. The obtained results of the form factors then adopted in the calculations of the corresponding widths. The present results can be used in future experiments for studying the properties of JP=2- tensor mesons. © 2025 authors. Published by the American Physical Society.
