Abstract We perform the first calculation of form factors in the semileptonic decays B → D 1(2420)ℓν ℓ and B → D 1 ′ $$ {D}_1^{\prime } $$ (2430)ℓν ℓ using QCD light-cone sum rules (LCSRs) with B-meson distribution amplitudes. In this calculation the c-quark mass is finite. Analytical expressions fo...
