Abstract
The properties of -hyperons in pure matter are studied with the finite-density quantum chromo-dynamics sum rule (QCDSR) approach. The nuclear potential is most likely strongly attractive, it could be about -50 MeV or even more attractive at normal nuclear density. If this prediction is the case, the interactions between -hyperons should play crucial roles in the strange nuclear matter, when there are multi- hyperons. The bound state of double- maybe exist.
