Description

We present the next-to-leading order (NLO) calculation of associated hadroproduction of $J/\psi$ plus $W$ or $Z$ bosons within the factorization framework of nonrelativistic QCD (NRQCD). We compare to ATLAS data using various sets of nonperturbative long distance matrix elements (LDMEs) as input. Our results thereby open up a new angle in the ongoing quest to understand whether the LDMEs are universal or not. We give an overview of how these NLO universality tests now unfold, after the inclusion of our new results.
