Description

I'll discuss calculation of the NLO corrections to the unpolarized quark TMDPDFs using the factorization scheme defined in arXiv:2311.16402. The scheme aims to take into account the all collinear twist content of the TMDPDFs in the region of large $b_\perp\lesssim\Lambda^{-1}_{QCD}$ and bridge together the limits of large and small-x. I'll discuss different aspects of this derivation including the role of the QCD equations of motion.
