Heavy Quarkonia on the Light Front

ORAL

Abstract

We employ solutions for heavy quarkonium within a light-front basis function approach [1] to compare with experiment and predict additional observables. The Hamiltonian is based on the Light-Front Holographic QCD (phenomenological confinement) plus one-gluon exchange. Mass spectra agree well with experiment and we employ the wavefunctions to evaluate decay constants and form factors. We discuss our progress and plans for evaluating generalized parton distributions (GPDs) and cross sections for diffractive production. Our predictions for these observables as well as predictions of additional excited states can be tested at ongoing and future experimental facilities, e.g., LHC, sPHENIX and the EIC. [1] Y. Li, P.
