Instantons in N = 2 magnetized D–brane worlds


In a toroidal orbifold of type IIB string theory we study instanton effects in N = 2 super Yang-Mills theories engineered with systems of wrappedmagnetized D9 branes and Euclidean D5 branes. We analyze the various open string sectors in this brane system and study the 1-loop amplitudes described by annulus diagrams with mixed boundary conditions, explaining… (More)
