Decay constants and form factors of s-wave and p-wave mesons in the covariant light-front quark model

Understand

We reanalyze the decay constants of s-wave and p-wave mesons and D, B ->M form factors, where M represents a pseudoscalar meson, a vector meson, a scalar meson, or an axial vector meson within a covariant light-front quark model.

• The parameter \beta for wave-functions of most of s-wave mesons and of a few axial-vector mesons are fixed with latest experimental information, wherever available or using the lattice calculations.
• The treatment of masses and mixing angles for strange axial vector mesons is improved for the purpose.
• We extend our analysis to determine the form factors appearing in the transition of D_s, B_s->M transitions, and to the isoscalar final state mesons.
