Updating Boer-Mulders functions from unpolarized pd and pp Drell-Yan data

We extract the Boer-Mulders functions for the proton by combining the unpolarized pd and pp Drell-Yan data measured by the E866/NuSea Collaboration by the assumption that the \(\cos 2\phi\) asymmetry is from the Boer-Mulders function. Using the extracted Boer-Mulders functions, we present the predic...

Description
Summary:We extract the Boer-Mulders functions for the proton by combining the unpolarized pd and pp Drell-Yan data measured by the E866/NuSea Collaboration by the assumption that the \(\cos 2\phi\) asymmetry is from the Boer-Mulders function. Using the extracted Boer-Mulders functions, we present the predictions for the \(\cos 2 \phi\) asymmetries in future pp experiments at J-PARC and \(p \bar{p}\) experiments at PANDA and PAX.
