摘要：
Based on five di fferent ensembles of newly generated (2 +1)-flavor configurations with pion mass of approximately m p.(140310) MeV, we present a lattice analysis of hidden-charm and hidden-strange hexaquarks with the quark content uscd sc. The correlation matrices of two types of operators with JPC = 0++, 0-+, 1++ and 1-- are simulated to extract the masses of the hexaquark candidates, which are subsequently extrapolated to the physical pion mass and continuum limit. The results indicate that ground state masses are below the. c . c threshold and provide a characteristic signal for the experimental discovery of hexaquark candidates, which may enrich the versatile structure of multiquarks; moreover, it is an indispensable step to decipher the nonperturbative nature of the fundamental interactions of quarks and gluons.
