The Witten index in supersymmetric gauge theories [PDF]
Physics Letters B, 1984 Abstract Difficulties in the calculation of the Witten index in gauge theories are pointed out. Such difficulties are due to ambiguities in the identification of all the zero energy states and to the fact that some of these states belong to a continuous spectrum.

A functional treatment of small instanton-induced axion potentials
Journal of High Energy PhysicsWe present a functional method to perform complete one-instanton calculations of the axion potential. This is done for an SU(N) gauge theory with a matter content in any representation of the gauge group.

Manifestly N=2 supersymmetric regularization for N=2 supersymmetric field theories
Physics Letters B, 2015 We formulate the higher covariant derivative regularization for N=2 supersymmetric gauge theories in N=2 harmonic superspace. This regularization is constructed by adding the N=2 supersymmetric higher derivative term to the classical action and inserting

Quantum K-theory of Calabi-Yau manifolds
Journal of High Energy Physics, 2019 The disk partition function of certain 3d N = 2 supersymmetric gauge theories computes a quantum K-theoretic ring for Kähler manifolds X. We study the 3d gauge theory/quantum K-theory correspondence for global and local Calabi-Yau manifolds with several ...

Exact Superpotentials, Theories with Flavor and Confining Vacua
, 2004 In this paper we study some interesting properties of the effective superpotential of N=1 supersymmetric gauge theories with fundamental matter, with the help of the Dijkgraaf--Vafa proposal connecting supersymmetric gauge theories with matrix models ...

The four-loop DRED gauge beta-function and fermion mass anomalous dimension for general gauge groups
, 2007 We present four-loop results for the gauge beta-function and the fermion mass anomalous dimension for a gauge theory with a general gauge group and a multiplet of fermions transforming according to an arbitrary representation, calculated using the ...

Supersymmetric quantization of gauge theories
, 1995 We develop a new operator quantization scheme for gauge theories in which the dynamics of the ghost sector is described by an N=2 supersymmetry. In this scheme no gauge condition is imposed on the gauge fields. The corresponding path integral is explicitly Lorentz invariant and, in contrast to the BRST-BFV path integral in the Lorentz gauge, it is free

Non-lattice simulation for supersymmetric gauge theories in one dimension
, 2007 Lattice simulation of supersymmetric gauge theories is not straightforward. In some cases the lack of manifest supersymmetry just necessitates cumbersome fine-tuning, but in the worse cases the chiral and/or Majorana nature of fermions makes it difficult
