We consider the transverse momentum spectrum of quarkonium produced in hadronic collisions. For traverse momentum parametrically smaller compared to its mass, in the central rapidity region, the quarkonium is produced nearly at rest and other particles in the event can only be soft and/or collinear along the beam direction. We use non-relativistic QCD (NRQCD) to describe the dynamics of the heavy quark antiquark pair where the light degrees of freedom are incorporated through soft collinear effective theory (SCET). We investigate the unpolarized cross section as well as the transverse single spin asymmetry (TSSA) for the initial state hadrons.
