Description
In this analysis, we report a comparison of transverse momentum dependent parton distribution functions (TMDPDFs) between pions and protons through a simultaneous extraction of collinear and transverse degrees of freedom in the pion. We extract proton TMDPDFs along with pion TMDPDFs from low transverse-momentum dependent fixed-target Drell-Yan data as well as collinear pion PDFs from Drell-Yan and leading neutron data, marking the first analysis of its kind. We observe a very distinctive behavior of the conditional expectation value of the transverse separation of quarks for a given $x$. We provide some possible explanation of the phenomena and new avenues for further explorations.
