Light-cone limits of large rectangular fishnets
Light-cone limits of large rectangular fishnets
Basso-Dixon integrals evaluate rectangular fishnets -- Feynman graphs with massless scalar propagators which form a $m\times n$ rectangular grid -- which arise in certain one-trace four-point correlators in the `fishnet' limit of $\mathcal{N}=4$ SYM. Recently, Basso {\it et al} explored the thermodynamical limit $m\to\infty$ with fixed aspect ratio $n/m$ of …
