Polarised and Unpolarised Charmonium Production at Higher Orders in v
Sourendu Gupta, Prakash Mathews
Abstract
We study the unpolarised and polarised hadro-production of charmonium in non-relativistic QCD (NRQCD) at low transverse momentum, including sufficiently higher orders in the relative velocity, v, so as to study the ratio of χc1 and χc2 production rates.
