N2 - Using lowest-order lattice nonrelativistic QCD to create heavy meson propagators and applying the spin-dependent interaction, cB(-g/2mq)σ→-B→, at varying intermediate time slices, we compute the off-diagonal matrix element of the Hamiltonian for the quarkonium-hybrid two-state system. Thus far, we have results for one set of quenched lattices with an interpolation in quark mass to match the bottomonium spectrum. After diagonalization of the two-state Hamiltonian, we find the ground state of the Y to show a 0.0035(1)cB2 (with cB2∼1.5-3.1) probability admixture of hybrid, |bb̄g〉.
