摘要The associate J/psi + gamma production at the LHC is studied completely at next-to-leading order within the framework of nonrelativistic QCD. By using three sets of color-octet long-distance matrix elements obtained in previous prompt J/psi studies, we find that only one of them can result in a positive transverse momentum (p(t)) distribution of J/psi production rate at the large p(t) region. Based on reasonable consideration to cut down background, our estimation is measurable up to p(t) = 50 GeV with the present data sample collected at 8 TeV LHC. All the color-octet long-distance matrix elements in J/psi production could be fixed sensitively by including this proposed measurement and our calculation, and then a confident conclusion on the J/psi polarization puzzle could be achieved.
