Title: Impact of Hexaquark H Particle on Compact Star Properties
Abstract： We study the possible existence of the hexaquark H particle (uuddss) in neutron stars. Within the Chromomagnetic Interaction framework, the flavor-singlet H exhibits a mass of 2212.7 MeV. Using the relativistic mean-field model, we explore how H particle couplings influence neutron star structure. Our results indicate that H particles could persist as stable constituents, reducing the maximum mass and providing new insights into the dense matter equation of state.
