Abstract
Dibaryons provide insight into the strong interaction beyond conventional hadrons Strange dibaryons, containing strange quarks, are especially valuable for probing hyperon-nucleon (YN) and hyperon-hyperon (FF) interactions. We report measurements of p–Ξ− and p–Ω− correlation functions in Ru+Ru and Zr+Zr collisions at √sNN = 200 GeV. The analysis, using the Lednicky-Lyuboshitz formalism, yields scattering parameters that offer key implications for the possible formation of strange dibaryon bound states, particularly H (S = −2) and NΩ (S = −3).
