Relations among B c → J/ψ, η c form factors

Relations among B c → J/ψ, η c form factors

Abstract We analyze the form factors parametrizing the B c → J/ψ, η c matrix elements of the operators in a generalized low-energy b → c semileptonic Hamiltonian. We consider an expansion in nonrelativistic QCD, classifying the heavy quark spin symmetry breaking terms and expressing the form factors...
