production in jets using NRQCD
Marston Copeland, Lin Dai, Yu Fu +1
Based on recent data from LHCb, we study production in jets using non-relativistic QCD (NRQCD) in conjunction with the Fragmenting Jet Function (FJF) and Gluon Fragmentati…
Factorizing quarkonium LDMEs and TMDSTFs using effective field theory
Marston Copeland
We use effective field theory to factorize production matrix elements that appear in the NRQCD framework for quarkonium cross sections. By applying a Hubbard-Stratonovich transform…
Factorizing quarkonium production matrix elements using effective field theory
Marston Copeland, Ivan Vitev
We use effective field theory to factorize production matrix elements that appear in quarkonium cross sections in NRQCD. By applying a Hubbard-Stratonovich transformation we show t…
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 …
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…
