%X An exploration of nucleon TMD observables at a substantially lower pion mass, 170 MeV, than used in previous lattice TMD calculations is presented. On a corresponding RBC/UKQCD domain wall fermion ensemble, TMDs are extracted from nucleon matrix elements of a bilocal quark operator containing a staple-shaped gauge link. Appropria te TMD ratios are constructed to cancel divergences associated with the gauge link. In particular, results associated with the time-reversal odd Sivers effect and with the quark transversity are report ed. They are compared with previous domain wall fermion calculations at 297 MeV pion mass with a v iew to exploring whether these observables vary strongly as a function of pion mass in the chiral regime.
