Abstract: (arXiv)

The coalescence production of sexaquark, a hypothetical stable state with quark content

(uuddss)

, is investigated by the parton and hadron cascade model PACIAE in

pp

collisions at

\sqrt s = 7

TeV. In this work, the compact sexaquark bound state of three diquarks is formed in the final partonic state by a two-step approach, which involves ``diquark" formation via partonic coalescence and sexaquark construction with dynamically constrained phase-space coalescence model successively. The yields, yield ratios, and dependences of spatial parameters (the size of diquark

D_{0}

and the radius of sexaquark

R_{0}

) of (anti-)sexaquark are predicted. The yields of a hadronic molecule H-dibaryon

\mathrm{H}(\Lambda\Lambda)

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.
