New sum rules for the B c → J/ψ form factors
Abstract We derive new sum rules for the form factors of the B c → J / ψ ℓ ν ¯ ℓ $$ {B}_c\to J/\psi \ell {\overline{\nu}}_{\ell } $$ semileptonic transitions, employing the vacuum-to-B c correlation function of the J/ψ-interpolating and b → c weak currents. In the heavy quark limit and at a space-li...
