Probing non-perturbative effects in M-theory on orientifolds (1511.02635v1)
Published 9 Nov 2015 in hep-th
Abstract: Using holography, we study non-perturbative effects in M-theory on orientifolds from the analysis of the S3 partition functions of dual field theories. We consider the S3 partition functions of N=4 Yang-Mills theory with O(n) gauge symmetry coupled to one (anti)symmetric and N_f fundamental hypermultiplets from the Fermi gas approach. In addition to the worldsheet instanton and membrane instanton corrections to the grand potential, which are also present in the U(n) Yang-Mills case, we find that there exist "half instanton" corrections coming from the effect of orientifold plane.
