Form Factors and Generalized Parton Distributions of Heavy Quarkonia in Basis Light Front Quantization

Understand

We calculate the electromagnetic (charge, magnetic and quadrupole) form factors and the associated static moments of heavy quarkonia (charmonia and bottomonia) using the Basis Light Front Quantization (BLFQ) approach.

• For this work, we adopt light front wavefunctions (LFWFs) generated by a holographic QCD confining potential and a one-gluon exchange interaction with fixed coupling.
• We compare our BLFQ results with the limiting case of a single BLFQ basis state description of heavy quarkonia and with other available results.
• These comparisons provide insights into relativistic effects.
