$p{\Xi }^{-}$ Correlation in Relativistic Heavy Ion Collisions with Nucleon-Hyperon Interaction from Lattice QCD

Abstract

On the basis of the $p{\Xi }^{-}$ interaction extracted from (2+1)-flavor lattice QCD simulations at the physical point, the momentum correlation of $p$ and ${\Xi }^{-}$ produced in relativistic heavy ion collisions is evaluated. $C_{\mathrm{SL}}(Q)$ defined by a ratio of the momentum correlations between the systems with different source sizes is shown to be largely enhanced at low momentum due to the strong attraction between $p$ and ${\Xi }^{-}$ in the $I=J=0$ channel. Thus, measuring this ratio at RHIC and LHC and its comparison to the theoretical analysis will give a useful constraint on the $p{\Xi }^{-}$ interaction.
