The $\Sigma \Sigma$ interactions in finite-density QCD sum rules

P. Li, X. H. Zhong, L. Li +1

The properties of $\Sigma$-hyperons in pure $\Sigma$ matter are studied with the finite-density quantum chromo-dynamics sum rule (QCDSR) approach. The $\Sigma \Sigma$ nuclear potential $U_{\Sigma }$ is most li…
