Quarkonium wave functions on the light front

Understand

We study heavy quarkonium within the light-front Hamiltonian formalism.

• Our effective Hamiltonian is based on the holographic QCD confining potential and the one-gluon exchange interaction with a running coupling.
• The obtained spectra are compared with experimental measurements.
• We present a set of light-front wave functions, which exhibit rich structure and are consistent with the nonrelativistic picture.
