We calculate the leading twist valence quark transverse momentum parton distribution functions (TMDs) and generalized parton distributions (GPDs) of the charged kaons in an isospin symmetric nuclear matter at zero temperature by employing the light-cone quark model. The medium modifications of the unpolarized TMDs and GPDs have been carried out by taking inputs from the chiral SU(3) quark mean field model. The electromagnetic form factors (EMFFs) and charge radii have been calculated from the unpolarized GPDs for both the vacuum and in-medium cases. We have also calculated the variation of average transverse and longitudinal momenta for the active quark at high baryonic density. These results are found to be in good agreement with the available experimental data as well as with other model predictions.
