dc.description.abstractWe present evidence for the existence of a bound H dibaryon, an I = 0 , J = 0 , s = − 2 state with valence quark structure u u d d s s , at a pion mass of m π ∼ 389     MeV . Using the results of lattice QCD calculations performed on four ensembles of anisotropic clover gauge-field configurations, with spatial extents of L ∼ 2.0 , 2.5, 3.0, and 3.9 fm at a spatial lattice spacing of b s ∼ 0.123     fm , we find an H dibaryon bound by B H ∞ = 16.6 ± 2.1 ± 4.6     MeV at a pion mass of m π ∼ 389     MeV .-
