Dipole subtraction vs. phase space slicing in NLO NRQCD heavy-quarkonium production calculations
We compare two approaches to evaluate cross sections of heavy-quarkonium production at next-to-leading order in nonrelativistic QCD involving S- and P-wave Fock states: the customary approach based on phase space slicing and the approach based on dipole subtraction recently elaborated by us. We find...
