Description
Early results will be presented from a Lattice QCD study seeking a
bound H-dibaryon using Nf=2 flavors of O(a) improved Wilson fermions and a quenched strange quark. We solve the generalized eigenvalue problem constructed using a variational basis of interpolators consisting of the two independent local products of six positive-parity-projected quarks with the appropriate quantum numbers, which belong to the singlet and 27-plet irreducible representations of flavor SU(3). To expand this basis, we also independently vary the quark-field smearing. We employ a "blocking" algorithm for the contractions and all-mode-averaging in order to achieve high performance and large statistics. Results will be presented for at least two different pion masses.
