Description
In this talk, we discuss the properties of generalized parton distributions (GPDs) for the kaon and pion within the framework of the nonlocal chiral quark model (NLχQM). The valence quark GPDs of the kaon and pion are analyzed in detail with respect to their momentum fraction x and skewness ξ dependencies in the DGLAP and ERBL regions. Due to explicit chiral symmetry breaking, we observe a significant distortion of the kaon quark GPDs in the ERBL domain near $\xi=1$, which affects the D-term of the kaon. Through polynomiality, we obtain the gravitational form factors of the kaon and pion, analyze them in detail, and compare them with results from other effective models.
