A Solvable Tensor Field Theory
arXiv:1903.02907 · doi:10.1007/s11005-019-01245-0
Abstract
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-Bürmann resummation. Higher-point functions are then obtained recursively.
