The pentaquark potential, mass and density-density correlator

Abstract

We evaluate the static $qqqq\bar{q}$ potential in the quenched theory at $\beta=5.8$ and $\beta=6.0$ on a lattice of size $16^3\times 32$. The mass and density-density correlator for the $\Theta^+$ is investigated in the quenched theory at $\beta=6.0$ on lattices of size $16^3\times 32$, $24^3\times 32$ and $32^3 \times 64$.
