Abstract

In this work, we investigate the interaction between the Ω baryon and the ss¯ meson within the framework of the quark delocalization color-screening model. The spectra calculations show that no bound state is formed in any of the considered channels, while the scattering indicates that the Ωϕ interaction with JP=1/2− is weakly attractive. As for the Ωϕ interactions with JP=3/2− and 5/2−, as well as the Ωη′ interaction with JP=3/2−, they are all repulsive. After an investigation on the femtoscopic correlation functions, we find that, due to the spin-averaging effect, the overall Ωϕ correlation function exhibits a weak dependence on the source size, which provides a crucial significance of our model for future experimental examinations in relativistic heavy-ion collisions.
