Skeleton expansion and large spin bootstrap for $\phi^3$ theory

Abstract

We study skeleton expansion of $\phi^3$ theory in $6+\epsilon$ dimensions as well as its global symmetry generalizations. We use it to compute the four point function of the scalar field $\phi$ up to $\epsilon^2$. We also do a large spin bootstrap approach to the same model up to order $\epsilon^2$ and check that both results agree.
