An Elliptic Superpotential for Softly Broken N = 4 Supersymmetric Yang-Mills Theory
نویسنده
چکیده
An exact superpotential is derived for the N = 1 theories which arise as massive deformations of N = 4 supersymmetric Yang-Mills (SYM) theory. The superpotential of the SU(N) theory formulated on R3×S1 is shown to coincide with the complexified potential of the N -body elliptic Calogero-Moser Hamiltonian. This superpotential reproduces the vacuum structure predicted by Donagi and Witten for the corresponding four-dimensional theory and also transforms covariantly under the S-duality group of N = 4 SYM. The analysis yields exact formulae with interesting modular properties for the condensates of gauge-invariant chiral operators in the four-dimensional theory.

Whitham Prepotential and Superpotential
N = 2 supersymmetric U(N) Yang-Mills theory softly broken to N = 1 by the superpotential of the adjoint scalar fields is discussed from the viewpoint of the Whitham deformation theory for prepotential. With proper identification of the superpotential we derive the matrix model curve from the condition that the mixed second derivatives of the Whitham prepotential have a nontrivial kernel. e-mail...
متن کاملSupersymmetric Yang-Mills Theory
We study the spectrum of the softly broken generalized Veneziano-Yankielowicz effective action for N = 1 SUSY Yang-Mills theory. Two dual formulations of the effective action are given. The spurion method is used for the soft SUSY breaking. Masses of the bound states are calculated and mixing patterns are discussed. Mass splittings of pure gluonic states are consistent with predictions of conve...
متن کاملGauge Singlet Renormalisation in Softly-Broken Supersymmetric Theories
We consider the renormalisation of a softly-broken supersymmetric theory with singlet fields and a superpotential with a linear term. We show that there exist exact β-functions for both the linear term in the superpotential and the associated linear term in the Lagrangian. We also construct exact renormalisation group invariant trajectories for these terms, corresponding to the conformal anomal...
متن کاملNon Supersymmetric Metastable Vacua in N = 2 Sym Softly Broken to N = 1
We find non-supersymmetric metastable vacua in four dimensional N = 2 gauge theories softly broken to N = 1 by a superpotential term. First we study the simplest case, namely the SU (2) gauge theory without flavors. We study the spectrum and lifetime of the metastable vacuum and possible embeddings of the model in UV complete theories. Then we consider larger gauge group theories with flavors. ...
متن کاملExtended Supersymmetric Moduli Space and a SUSY/Non-SUSY Duality
We study N = 1 supersymmetric U(N) gauge theories coupled to an adjoint chiral field with superpotential. We consider the full supersymmetric moduli space of these theories obtained by adding all allowed chiral operators. These include higher-dimensional operators that introduce a field-dependence for the gauge coupling. We show how Feynman diagram/matrix model/string theoretic techniques can a...
