Title
φ43 Revisited
Abstract
During the late seventies and early eighties, a huge research effort was undertaken to construct the φ43 theory, the simplest Euclidean QFT requiring non-trivial renormalisation beyond Wick ordering. The construction of this and closely related models has been revisited recently using completely different techniques, allowing to strengthen and clarify previous results, as well as to obtain some new results.
