Duality in supersymmetric gauge theories
Paolo Di Vecchia
In these lectures we discuss various aspects of gauge theories with extended and supersymmetry that are at the basis of recently found exact results. These results incl…
Two-loop scalar diagrams from string theory
Paolo Di Vecchia, Alberto Lerda, Lorenzo Magnea +2
We show how to obtain correctly normalized expressions for the Feynman diagrams of theory with an internal symmetry group, starting from tachyon amplitudes of the open…
String-derived renormalization of Yang-Mills theory
Paolo Di Vecchia, Alberto Lerda, Lorenzo Magnea +2
We review the application of bosonic string techniques to the calculation of renormalization constants and effective actions in Yang-Mills theory. We display the multiloop string f…
String techniques for the calculation of renormalization constants in field theory
P. Di Vecchia, A. Lerda, L. Magnea +2
We describe a set of methods to calculate gauge theory renormalization constants from string theory, all based on a consistent prescription to continue off shell open bosonic strin…
