Description
We investigate the strangeonia and strange mesons system in Basis Light-front Quantization(BLFQ) approach. We adopt a light-front effective Hamiltonian with transverse and longitudinal light-front holography confining potential. The effective Hamiltonian is retaining up to the first two Fock sector therefore we can contain one gluon dynamics in the meson system. This work is based on our light mesons' research. We only retune the parameter controlling the quark mass to adapt the strangeonia and strange mesons system. We obtain the optimal strange quark mass by fitting to the mass spectrum of strangeonia. Subsequently, We adopt the strange quark mass and the light quark mass obtained in our light mesons' research to calculate the strange mesons. We compute the mass spectroscopy, decay width, decay constants, the r.m.s radii, the distribution amplitudes(DAs) and the parton distribution functions (PDFs) of vanlence quark and gloun for the strangeonia and strange mesons system. We also obtain the electromagnetic form factor of $ K_{0}(494) $. Our results shows a reasonable description of the strangeonia and strange mesons system.
