[RBRC Seminar] First global QCD analysis of the worm-gear TMD $g_{1T}$

by Dr Shohini Bhattacharya


In this talk, we report on the first global extraction of the worm-gear function $g_{1T}$, one of the eight leading-twist TMDs. The study analyzes simultaneously the HERMES, COMPASS and JLab semi-inclusive deep-inelastic scattering data using Monte Carlo techniques. We provide a comparison of $g_{1T}$ obtained from this experimental data with different theoretical approaches, such as the large $N_c$ approximation, the Wandzura-Wilczek-type approximation, and lattice QCD.
