$B_c$ mesons and their properties on the light front

Understand

We investigate the unequal mass relativistic bound state system, the $B_c$ 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.
• We present the mass spectrum and light-front wave functions.
