Universally Finite Gravitational & Gauge Theories

Understand

It is well known that standard gauge theories are renormalizable in D=4 while Einstein gravity is renormalizable in D=2.

• This is where the research in the field of two derivatives theories is currently standing.
• We hereby present a class of weakly non-local higher derivative gravitational and gauge theories universally consistent at quantum level in any spacetime dimension.
• These theories are unitary (ghost-free) and perturbatively renormalizable.
