抄録: | On the basis of the pΞ⁻ interaction extracted from (2+1)-flavor lattice QCD simulations at the physical point, the momentum correlation of p and Ξ⁻ produced in relativistic heavy ion collisions is evaluated. CSL (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 Ξ⁻ 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 pΞ⁻ interaction. |
