Mr Reed Hodges (Duke University)

Description

We derive the leading-order polarized transverse momentum dependent fragmentation functions (TMDFFs) for light quark and gluon partons fragmenting to a $J/\psi$, and match the TMDFFs onto NRQCD. While unpolarized TMDFFs for quarkonium have been computed, a systematic treatment of the FFs for polarized quarkonium and parton has yet to appear in the literature. This will be crucial for making predictions for $J/\psi$ production cross sections at low transverse momentum, and allow for new tests of the NRQCD factorization formalism.
