Abstract: We present a new calculation of the semileptonic tree-level and flavor-changing neutral current form factors describing $B$-meson transitions to tensor mesons $T=D_2^*,K_2^*,a_2,f_2$ ($J^{P}=2^{+}$). We employ the QCD Light-Cone Sum Rules approach with $B$-meson distribution amplitudes.… read more here.

DOI: 10.1140/epjc/s10052-020-7637-z
Abstract: We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor $$\mathbf {6}_F$$ representation. In Cui et al. (Phys Rev D 99:094021, 2019) we have… read more here.
