Proposal for measuring new transverse momentum dependent parton distributions $g_{1T}$ and $h_{1L}^{\perp }$ through semi-inclusive deep inelastic scattering

Abstract

We calculate $g_{1T}$ and $h_{1L}^{\perp }$, two of the eight leading twist transverse momentum dependent parton distributions (TMDs), in the light-cone quark-diquark model. The new TMDs can be measured through semi-inclusive deep inelastic scattering (SIDIS). We present predictions of the single and double spin asymmetries related to $g_{1T}$ and $h_{1L}^{\perp }$ in SIDIS at HERMES, COMPASS, and JLab kinematics respectively.
