String Theory seminar - Francesco Sannino Seminar

I will discuss new exact results in four-dimensional quantum field theory that led to the discovery to asymptotically safe theories in four dimensions without supersymmetry. I will also discuss supersymmetric extensions and present new exact results that make use of a number of non-perturbative exact tools ranging from the unitary of the conformal operators to the a-theorem and maximisation. The results have far reaching consequences for the construction of novel extensions of the standard model of particle interactions.
