Examination of subleading twist proton TMD gTν in the light-front quark-diquark model

Abstract

We have examined the subleading twist T-even transverse momentum dependent parton distribution (TMD) gνT (x, p⊥2) for proton in the light-front quark-diquark model (LFQDM). For semi-inclusive deep inelastic scattering (SIDIS), we have decrypted the unintegrated quark-quark correlator and derived the explicit expression of the TMD gνT (x, p2⊥) by considering the both scalar and vector diquarks. The 2-D and 3-D plots of this TMD for both up and down quarks have been examined. Expression of TMD gνT (x, p2⊥) in the form of available results leading twist TMDs g⊥q1T (x, p⊥) and hq1(x, p⊥) has been provided. Plot of transverse momentum-dependent parton distribution function (TMDPDF) gνT (x) have also been provided.
