Contribution

It presents the first lattice QCD calculations of the pentaquark potential, mass, and density correlator in quenched theory at multiple lattice sizes and couplings.

Findings

Calculated static pentaquark potential at two lattice couplings.

Analyzed mass and density-density correlator for the $ heta^+$ pentaquark.

Provided data on pentaquark properties across different lattice sizes.

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 $32^3 \times 64$.
