Gravitational form factor of the kaon in holographic QCD

Year: 2025

Type: article

Abstract: The gravitational form factor (GFF) of the kaon is investigated in a bottom-up holographic QCD model, in which the strange quark mass breaks the SU(3) flavor symmetry. The probe energy ( Q 2 ) dependence of the kaon GFF is explicitly shown and compared to that of the pion. It is presented that our result shows the 1 / Q 2 behavior in the high energy region, which is consistent with the perturbative QCD prediction. The gravitational radius of the kaon is also calculated, and it is found that the result is quite close to that of the pion but slightly smaller.
