Abstract

Using lowest-order lattice NRQCD to create heavy meson propagators and applying the spin-dependent interaction, c_B (-g)/(2m_q)σ⋅B, at varying intermediate time slices, we compute the off-diagonal matrix element of the Hamiltonian for the quarkonium-hybrid two-state system. Diagonalizing this two-state Hamiltonian, the admixture of hybrid (|QQg>) in the ground state is found. We present results from a set of quenched lattices with an interpolation in quark mass to match the bottomonium spectrum.
