Description

We show that the transverse momentum dependent parton distribution functions
(TMDPDFs), important for understanding 3D hadron structure and describing
high-energy experiments, can be formulated in the framework of the
large-momentum effective theory(LaMET). We show that the quasi-TMDPDFs,
calculable on lattice, factorize at large momentum limit into physical-TMDPDFs
and reduced soft functions. We show that the reduced soft function can be
realized as a form-factor and can be extracted by combining lattice calculable
quasi-light-front wave functions and light-meson form-factors at large momentum
transfer. This paves the wave for first-principle determination of TMDPDFs and
Drell-Yan cross sections.
