    "abstract": "Accurate numerical solution of the five-body Schrodinger equation is effected\nvia variational Monte Carlo. The spectrum is assumed to exhibit a narrow\nresonance with strangeness S=+1. A fully antisymmetrized and pair-correlated\nfive-quark wave function is obtained for the assumed non-relativistic\nHamiltonian which has spin, isospin, and color dependent pair interactions and\nmany-body confining terms which are fixed by the non-exotic spectra. Gauge\nfield dynamics are modeled via flux tube exchange factors. The energy\ndetermined for the ground states with J=1/2 and negative (positive) parity is\n2.22 GeV (2.50 GeV). A lower energy negative parity state is consistent with\nrecent lattice results. The short-range structure of the state is analyzed via\nits diquark content.",
