dc.description新粒子「ダイオメガ」 --スパコン「京」と数理で予言するクォーク6個の新世界--. 京都大学プレスリリース. 2018-05-29.ja
dc.description.abstractThe ΩΩ system in the 1S0 channel (the most strange dibaryon) is studied on the basis of the (2+1)-flavor lattice QCD simulations with a large volume (8.1 fm)3 and nearly physical pion mass mπ≃146 MeV at a lattice spacing of a≃0.0846 fm. We show that lattice QCD data analysis by the HAL QCD method leads to the scattering length a0=4.6(6)(+1.2−0.5) fm, the effective range reff=1.27(3)(+0.06−0.03) fm, and the binding energy BΩΩ=1.6(6)(+0.7−0.6) MeV. These results indicate that the ΩΩ system has an overall attraction and is located near the unitary regime. Such a system can be best searched experimentally by the pair-momentum correlation in relativistic heavy-ion collisions.en
