Description
The sexaquark is a stable state with quark content ( u u d d s s) hypothesized by [1] which might be a candidate for dark matter in the Universe. We present results [2] on the coalescence production of the sexaquark using the parton and hadron cascade model PACIAE in p+p collisions at sqrt(s) = 7 TeV. The yields, yield ratios, and dependences of the spatial parameters (the size of the diquark D 0 and the radius of the sexaquark R 0) of a (anti)sexaquark are predicted. The yields of the hadronic H-dibaryon molecule H ( Λ Λ) generated in the final hadronic state are also compared. These estimates provide references for future sexaquark searches and other exotic state studies, such as dibaryons.
