Title : ( Stringy instantons in SU(N) $ \mathcal{N} = {2} $ non-conformal gauge theories )
Authors: Parsa Ghorbani , Daniele Musso ,
Full TextAbstract
In this paper we explicitly obtain the leading corrections to the SU(N ) N = 2 prepotential due to stringy instantons both in flat space-time and in the presence of a non-trivial graviphoton background field. We show that the stringy corrections to the prepotential are expressible in terms of the elementary symmetric polynomials. For N > 2 the theory is not conformal; we discuss the introduction of an explicit dependence on the string scale α 0 in the low-energy effective action through the stringy non-perturbative sector.
