We extract the pion transverse momentum dependent (TMD) parton distribu- tion by fitting the pion-induced Drell-Yan process within the framework of TMD factoriza- tion. The analysis is done at the next-to-next-to-leading order (NNLO) with proton TMD distribution and non-perturbative TMD evolution extracted earlier in the global fit. WebThe Drell-Yan process occurs as a result of hadron-hadron scattering in which a quark and antiquark of two respective hadrons annihilate. This forms a virtual photon that decays into an oppositely-charged lepton pair. 5 Figure 1: Feynman diagram of the Drell-Yan process.
