Description

In this presentation, we discuss the properties of the generalized valence-quark distribution functions of the kaon, based on an effective chiral-quark model approach. We compute the valence strange and light quark distributions of the kaon, $H^{q/{K^+}}(x, \xi, t) $, for the ERBL and DGLAP region by adopting the nonlocal chiral quark model defined at a low-renormalization point $\mu \approx 600~$MeV.
The computed GPDs exihibit continuous behavior at the cross-over points $x=\xi$ but their 1st derivatives do not. Also, we observe that the light quark distribution present stronger dependence on -t compared with the strange quark distribution. The gravitational form factors, derived from the second Mellin moments of the quark GPDs of the kaon, will be discussed in detail.
