Polarised and Unpolarised Charmonium Production at Higher Orders in v

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 ${\chi }_{c1}$ and ${\chi }_{c2}$ production rates.
