Query: Study of kaon structure using the light-cone quark model   We investigate the various distributions explaining multi-dimensional
structure of kaon at the level of its constituents ($u$ and $\bar{s}$) using
the light-cone quark model. The overlap form of wavefunctions associated with
the light-cone quark model is adopted for the calculations. The generalized
parton distributions(GPDs)of $u$ and $\bar{s}$ quarks are presented for the
case when the momentum transfer in the longitudinal direction is non-zero. The
dependence of kaon GPDs is studied in terms of variation of quark longitudinal
momentum fraction, momentum transfer in longitudinal direction and total
momentum transfer to the final state of hadron. The transverse impact-parameter
dependent GPDs are also studied by taking the Fourier transformation of general
GPDs. Further, the quantum phase-space distributions; Wigner distributions are
studied for the case of unpolarized, longitudinally-polarized and
transversely-polarized parton in an unpolarized kaon. The Wigner distributions
are analysed in the transverse impact-parameter plane, the transverse momentum
plane and the mixed plane. Further, to get a complete picture of kaon in terms
of its valence quarks, the variation of longitudinal momentum fraction carried
by quark and antiquark in the generalized transverse momentum-dependent parton
distributions (GTMDs) is studied for different values of transverse quark and
antiquark momentum $({\bf k}_\perp)$ as well as for different values of
momentum transferred to the kaon in transverse direction $({\bf
\Delta}_\perp)$. This has been done for zero as well as non-zero skewedness
representing respectively the absence and presence of momentum transfer to the
final state of kaon in longitudinal direction. Furthermore, the possible
spin-orbit correlation for $u$ and $\bar{s}$ in kaon is elaborated in context
of Wigner distributions and GTMDs.
