Abstract
Previous Lattice QCD calculations of nucleon transverse
momentum-dependent parton distributions (TMDs) focused
on the case of transversely polarized nucleons, and thus
did not encompass two leading-twist TMDs associated with
longitudinal polarization, namely, the helicity TMD and
the worm-gear TMD corresponding to transversely polarized
quarks in a longitudinally polarized nucleon. Based on a
definition of TMDs via hadronic matrix elements of quark
bilocal operators containing staple-shaped gauge connections,
TMD observables characterizing the aforementioned two TMDs
are evaluated, utilizing a RBC/UKQCD domain wall fermion
ensemble at the physical pion mass.
