“…It is found that if we put p T = 0 in Eq. ( 4), this equation will be casted to its usual form while there is not finally any transverse momentum dependence in the χQM [14,15]. In this case the splitting function P jB/i and also the q j distribution are given by expressions which are used in Refs.…”

Abstract. We investigate the transverse momentum dependent (TMD) quark and gluon distribution functions in the modified chiral quark model (χQM ). Calculations of the TMD quark and gluon densities, using the modified χQM are done for the first time in this article. For this propose we first formulate the TMD interactions that occur in the χQM at low Q 2 scale (Q 2 = 0.35 GeV 2 ) and then obtain the TMD parton distributions inside the proton, considering the interactions. To this end, we need to compute the TMD bare quark distributions. These TMD bare densities are calculated, using the solution of Dirac equation with a squared radial symmetry potential . It is shown that our results consist appropriate behavior which are expecting for the TMD parton distributions.

“…where m  is the mass of GS boson. If we take p T =0 in equation (4), the splitting function P j i  has no dependence on transverse momentum and the modified QM c is not, finally, transverse momentum dependent [39][40][41][42][47][48][49].…”

We investigate the unpolarized transverse momentum dependent (TMD) structure of light nuclei in the modified chiral quark exchange model (QEM), for the first time. To this end, we calculate the TMD quark and gluon distributions inside the bound state nucleons of the light nuclei based on the modified chiral quark model in which the TMD bare quark distributions of the bounded nucleons are needed. In order to compute these bare distributions, we first obtain the bare quark momentum densities using the QEM and then calculate the TMD bare distributions applying a theoretical method in which the light-cone variables are used. Finally, considering the nucleon structure of helium, tritium and deuteron nuclei, we obtain their TMD quark and gluon densities at low Q2 scale. It is shown that our results have appropriate properties that are expected for the TMD distribution functions.
