mesons and their properties on the light front
Abstract
We investigate the unequal-mass relativistic bound-state system, the Bc mesons, in a light-front Hamiltonian formalism. We adopt an effective Hamiltonian based on soft-wall light-front holography, together with a longitudinal confinement that was first introduced for heavy quarkonium. We also include the one-gluon-exchange interaction with a running coupling, which produces the spin structure. Here, we present the mass spectrum and light-front wave functions. We also use the light-front wave functions to calculate decay constants, charge and momentum densities, as well as distribution amplitudes. The results are compared with experiments and other theoretical approaches, all of which are in reasonable agreement.
