Description
The cross-sections of prompt and non-prompt production of $J/\psi+W^{\pm}$ are being measured by the ATLAS Collaboration using the $139~\textrm{fb}^{-1}$ Run II 13 TeV $pp$ collision data set. The prompt production of $J/\psi$ associated with a $W^{\pm}$, where both particles are produced in a single parton-parton interaction, provides constraints on models of non-relativistic QCD, especially in the realm of heavy quarkonia production. The measurement is an all-leptonic final state with $J/\psi\rightarrow\mu^+\mu^-$ and $W^{\pm}\rightarrow\ell^{\pm}\nu$, and it is performed differentially in $J/\psi$ transverse momentum and rapidity. Finally, the non-prompt measurement allows for the study of top production and $b$-quark fragmentation.
