Critical behavior of the PT-symmetric quantum field theory
Carl M. Bender, V. Branchina, Emanuele Messina
It was shown recently that a PT-symmetric quantum field theory in dimensions possesses a nontrivial fixed point. The critical behavior of this theory around the fixed…
A new, exact, gauge-invariant RG-flow equation
V. Branchina, K. A. Meissner, G. Veneziano
This paper has been withdrawn by the authors.
Renormalization Group with Condensate
Jean Alexandre, Vincenzo Branchina, Janos Polonyi
The renormalization group is applied to the phi4 model in the symmetry broken phase in order to identify different scaling regimes. The new scaling laws reflect nonuniversal behavi…
Mini-Instantons in SU(2) Gauge Theory
Vincenzo Branchina, Janos Polonyi
The effects of instantons close to the cut-off is studied in four dimensional SU(2) gauge theory with higher order derivative terms in the action. It is found in the framework of t…
Mini-Instantons
Vincenzo Branchina, Janos Polonyi
It is shown that the inhomogeneous saddle points of scale invariant theories make the semiclassical expansion sensitive on the choice of non-renormalizable operators. In particular…
