NRQCD colour-octet expansion vs LHC quarkonium production: signs of a hierarchy puzzle?
The observation of unpolarized quarkonium production in high energy pp collisions, at mid rapidity, implies a significant violation of the non-relativistic QCD (NRQCD) velocity scaling rules. A precise experimental confirmation of this picture could definitely rule out the current formulation of the...
