Key Points

  • The aim is to explore the existence of strange dibaryons and their interaction properties through measurements.
  • Analyzed p–Ξ− and p–Ω− correlation functions in Ru+Ru and Zr+Zr collisions
  • Utilized the Lednicky-Lyuboshitz formalism for data analysis
  • Calculated scattering parameters related to dibaryon bound states
  • Identified key scattering parameters that may indicate the formation of strange dibaryons.
  • Found significant correlation patterns in isobar collisions at √sNN = 200 GeV.
  • Highlighted implications for the potential existence of bound states like H (S = −2) and NΩ (S = −3).

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).
