Abstract

The ΞN\Xi N interaction plays an important role in our understanding on the long-anticipated HH-dibaryon. Recent lattice QCD calculations verified the attractive nature of the ΞN\Xi N interaction. On the other hand, whether it is strong enough to generate a bound state remains inconclusive.In this work, assuming that it can generate a weakly bound state, we study the yields of the ΞN\Xi N dibaryon for different binding energies in pppp collisions at 7 TeV using the coalescence model and the transport model PACIAE. The yields are estimated first numerically and then analytically adopting a Yukawa-type wave function. In particular, we find that in the weak binding limit, there exists a universal relation between the yield and the binding energy, valid for pppp collisions.
