英文摘要We investigate transition form factors of B meson decays into a scalar glueball in the light-cone formalism. Compared with form factors of B to ordinary scalar mesons, the B-to-glueball form factors have the same power in the expansion of 1/m(B). Taking into account the leading twist light-cone distribution amplitude, we find that they are numerically smaller than those form factors of B to ordinary scalar mesons. Semileptonic B -> Gl (nu) over bar, B -> Gl(+)l(-) and B-s -> Gl(+)l(-) decays are subsequently investigated. We also analyze the production rates of scalar mesons in semileptonic B decays in the presence of mixing between scalar (q) over barq and glueball states. The glueball production in B-c meson decays is also investigated and the LHCb experiment may discover this channel. The sizable branching fraction in B-c -> (pi(+)pi(-))l(-)(nu) over bar, B-c -> (K+K-)l(-)(nu) over bar or B-c -> (pi(+)pi(-)pi(+)pi(-))l(-)(nu) over bar could be a clear signal for a scalar glueball state.
