  In this work, we have established the relations between the T-even proton
transverse momentum-dependent parton distributions (TMDs) at all twist levels
up to twist-4 using the light-front quark diquark model (LFQDM). From the
parameterization equations of TMDs, we have found that there are multiple ways
by which a particular TMD can be expressed in terms of the helicities of the
proton in the initial and final states. For the first time, we have presented a
parameterization table that can be applied to the derivation and recognition of
proton TMDs based on their helicity. We have constructed the linear and
quadratic relationships of TMDs at the intra-twist and inter-twist levels
within the same model. We have also looked at the inequality relations that
TMDs follow. Additionally, to provide an easy access to the calculations,
amplitude matrices have been expressed in the form of TMDs over all the
possible helicities of the diquark.
