Abstract

Based on five different ensembles of newly generated(2+1)-flavor configurations with pion mass of approximately mπ(≌)(140-310)MeV,we present a lattice analysis of hidden-charm and hidden-strange hexaquarks with the quark content uscds(c).The correlation matrices of two types of operators with JPC=0++,0-+,1++and 1--are simulated to extract the masses of the hex-aquark candidates,which are subsequently extrapolated to the physical pion mass and continuum limit.The results indicate that ground state masses are below the Ξc(Ξ)c threshold and provide a characteristic signal for the experimental discovery of hex-aquark 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.
