Quantization in the Presence of Gribov Ambiguities
Martin Schaden
The non-perturbative validity of covariant BRST-quantization of gauge theories on compact Euclidean space-time manifolds is reviewed. BRST-quantization is related to the constructi…
Novel Local CFT and Exact Results on Perturbations of N=4 Super Yang Mills from AdS Dynamics
L. Girardello, M. Petrini, M. Porrati +1
We find new, local, non-supersymmetric conformal field theories obtained by relevant deformations of the N=4 super Yang Mills theory in the large limit. We contruct interpolati…
Massive Higher Spin States in String Theory and the Principle of Equivalence
Ioannis Giannakis, James T. Liu, Massimo Porrati
In this paper we study three point functions of the Type II superstring involving one graviton and two massive states, focusing in particular on the spin-7/2 fermions at the first…
Renormalizable Non-Covariant Gauges and Coulomb Gauge Limit
L. Baulieu, D. Zwanziger
To study ``physical'' gauges such as the Coulomb, light-cone, axial or temporal gauge, we consider ``interpolating'' gauges which interpolate linearly between a covariant gauge, su…
Supersymmetric Sum Rules for Electromagnetic Multipoles
Ioannis Giannakis, James T. Liu, Massimo Porrati
We derive model independent, non-perturbative supersymmetric sum rules for the magnetic and electric multipole moments of any theory with N=1 supersymmetry. We find that in any irr…
The Vacuum Energy Density of QCD with n_f=3 Quark Flavors
Martin Schaden
An equivariant BRST-construction is used to define the continuum SU(3) gauge theory on a finite torus. I corroborate previous results using renormalization group techniques by expl…
