The mean field description of nuclear matter in the quark-meson coupling model is improved by the inclusion of exchange contributions (Fock terms). The inclusion of Fock terms allows us to explore the momentum dependence of meson-nucleon vertices and the role of pionic degrees of freedom in matter.

We investigate the exclusive semileptonic B c → (D, η c , B, B s ) ν , η b → B c ν ( = e, μ, τ ) decays using the light-front quark model constrained by the variational principle for the QCD motivated effective Hamiltonian. The form factors f + (q 2 ) and f -(q 2 ) are obtained from the analytic con
