Measurement of $J/\psi$ production in association with a $W^{\pm }$ boson with $pp$ data at 8 TeV

Abstract

A measurement of the production of a prompt $J/\psi$ meson in association with a $W^{\pm }$ boson with $W^{\pm }\to \mu \nu$ and $J/\psi \to {\mu }^{+}{\mu }^{-}$ is presented for $J/\psi$ transverse momenta in the range 8.5-150 GeV and rapidity $|y_{J/\psi }|<2.1$ using ATLAS data recorded in 2012 at the LHC. The data were taken at a proton-proton centre-of-mass energy of $\sqrt{s}$ = 8 TeV and correspond to an integrated luminosity of 20.3 fb${}^{-1}$. The ratio of the prompt $J/\psi$ plus $W^{\pm }$ cross-section to the inclusive $W^{\pm }$ cross-section is presented as a differential measurement as a function of $J/\psi$ transverse momenta and compared with theoretical predictions using different double-parton-scattering cross-sections.
