Description
Recently, new four-dimensional (gauge-Yukawa) theories have been discovered which
display exact interacting fixed points at highest energies. In a regime where asymptotic
freedom is lost, these novel types of theories develop an asymptotically safe UV fixed
point, strictly controlled by perturbation theory. In this talk, we extend these studies to include couplings with non-vanishing canonical mass dimension. Using the method of
functional renormalisation, we determine the full fixed point potential including higher
order invariants of e.g. the scalar and fermionic fields. We also compute the universal
scaling exponents and establish consistency of the theory beyond the restriction to
classically marginal operators.
