Four-quark potentials for $SU(2)$ are evaluated in the static limit with the
quenched approximation -- using a lattice of $16^3\times 32$ and $\beta=2.4$.
The four quarks are restricted to the corners of rectangles with sides upto
seven lattice spacings long. The results are analysed in terms of a strategy
based on interquark two-body potentials -- as advocated earlier by the authors.
This shows that a standard two-body approach overestimates the four-quark
binding energy by upto a factor of about three for the largest rectangles.Comment: 26 pages, HU-TFT-92-1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
