| 英文摘要 | In the covariant light-front quark model, we investigate the B-c -> h(c), chi(c0,1,2) form factors. The form factors are evaluated in the spacelike kinematic region and are recasted to the physical region by adopting the exponential parametrization. We also study the semileptonic B-c decays and find that branching fractions for the B-c ->(h(c),chi(c0,1,2))l nu(l=e,mu) decays have the order 10(-3), while branching fractions for B-c ->(h(c),chi(c0,1,2))tau nu(tau) are suppressed by one order. These predictions will be tested on the forthcoming hadron colliders. |
