Аннотация: The coalescence production of the sexaquark, a hypothetical stable state with quark content (uuddss), is investigated using the parton and hadron cascade model PACIAE in pp collisions at √s = 7 TeV. In this work, the compact sexaquark bound state of three diquarks is formed in the final partonic state by a twostep approach, which involves “diquark” formation via partonic coalescence and sexaquark constructionwith the dynamically constrained phase-space coalescence model successively. The yields, yield ratios, and dependences of the spatial parameters (the size of the diquark D0 and the radius of the sexaquark R0) of a (anti)sexaquark are predicted. The yields of the hadronic H-dibaryon molecule H(ΛΛ) generated in thefinal hadronic state are also compared. These estimates provide references for future sexaquark searches and other exotic state studies, such as dibaryons.
