### Description

The variable $\varphi^\star$ probes the same physical effects as the $Z/\gamma^\star$ boson transverse momentum, but is less susceptible to the effects of experimental resolution and efficiency. Using 10.4 fb$^{−1}$ of proton-antiproton collisions collected by the D0 detector at the Fermilab Tevatron, we measure the distribution of the variable $\varphi^\star$ in events containing dimuon pairs with masses between 30 and 500 GeV. The data are corrected for detector effects and presented in bins of dimuon rapidity and mass.
