Relativistic corrections to exclusive photoproduction of Quarkonia near-threshold
Sarah K. Blask, Sean Fleming, Thomas Mehen +3
Non-relativistic QCD (NRQCD) is used to calculate the relativistic correction to the amplitude for exclusive photoproduction of vector Quarkonia in the near-threshold region within…

Probing nonperturbative transverse momentum dependent PDFs with chiral perturbation theory: the asymmetry
Marston Copeland, Thomas Mehen
We use chiral perturbation theory to study the long distance regime of transverse momentum dependent parton distribution functions (TMD PDFs). Chiral corrections to the TMD PDFs ar…

Quarkonium Semiclassical Transport in Quark-Gluon Plasma: Factorization and Quantum Correction
Xiaojun Yao, Thomas Mehen
We study quarkonium transport in the quark-gluon plasma by using the potential nonrelativistic QCD (pNRQCD) effective field theory and the framework of open quantum systems. We arg…
