Stringy instanton effects in N=2 gauge theories
Hossein Ghorbani, Daniele Musso, Alberto Lerda
We study the non-perturbative effects induced by stringy instantons on N=2 SU}(N) gauge theories in four dimensions, realized on fractional D3 branes in a C^3/Z_3 orientifold. The…

A pedagogical introduction to the Slavnov formulation of quantum Yang-Mills theory
Hossein Ghorbani, Giampiero Esposito
Over the last few years, Slavnov has proposed a formulation of quantum Yang-Mills theory in the Coulomb gauge which preserves simultaneously manifest Lorentz invariance and gauge i…
