A Solvable Tensor Field Theory
Romain Pascalie
文献摘要
We solve the closed Schwinger-Dyson equation for the 2-point function of a tensor field theory with a quartic melonic interaction, in terms of Lambert’s W-function, using a perturbative expansion and Lagrange-B"{u}rmann resummation. Higher-point functions are then obtained recursively.
