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…

The role of the soft scale for production in the transverse momentum dependent framework
Marston Copeland, Sean Fleming, Reed Hodges
We use vNRQCD to study power corrections in the expansion due to soft gluon radiation during production at small transverse momentum. We categorize four new …

Polarized production in semi-inclusive DIS at large : Comparing quark fragmentation and photon-gluon fusion
Marston Copeland, Sean Fleming, Rohit Gupta +2
We compare the relative importance of different mechanisms for polarized production in semi-inclusive deep inelastic scattering processes at large . The transverse mome…
