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

Gauge coupling unification in E 6 F-theory GUTs with matter and bulk exotics from flux breaking

, 2013
We consider gauge coupling unification in E 6 F-Theory Grand Unified Theories (GUTs) where E 6 is broken to the Standard Model (SM) gauge group using fluxes. In such models there are two types of exotics that can affect gauge coupling unification, namely

Supersymmetric domain walls in 7D maximal gauged supergravity

European Physical Journal C: Particles and Fields, 2019
We give a large class of supersymmetric domain walls in maximal seven-dimensional gauged supergravity with various types of gauge groups. Gaugings are described by components of the embedding tensor transforming in representations $$\mathbf {15}$$ 15 and

Topological Quantum Field Theory and the Geometric Langlands Correspondence [PDF]

, 2013
In the pioneering work of A. Kapustin and E. Witten, the geometric Langlands program of number theory was shown to be intimately related to duality of GL-twisted N=4 super Yang-Mills theory compactified on a Riemann surface. In this thesis, we generalize

A functional treatment of small instanton-induced axion potentials

Journal of High Energy Physics
We 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.

Wilson loop and its correlators in the limit of large coupling constant

Nuclear Physics B, 2018
In this paper we study Wilson loops in various representations for finite and large values of the color gauge group for supersymmetric N=4 gauge theories.

4d/2d Correspondence: Instantons and W-Algebras [PDF]

, 2012
In this thesis, we study the 4d/2d correspondence of Alday-Gaiotto-Tachikawa, which relates the class of 4-dimensional N=2 gauge theories (theories of class S) to a 2-dimensional conformal field theory. The 4d gauge theories are obtained by compactifying

Unitarity constraint on the Kähler curvature

Journal of High Energy Physics, 2018
In supersymmetric theories, the signs of quartic terms in the Kähler potential control the stability of non-supersymmetric field configurations.

Quantum MHV diagrams [PDF]

, 2016
Over the past two years, the use of on-shell techniques has deepened our understanding of the S-matrix of gauge theories and led to the calculation of many new scattering amplitudes.

Dualities and trialities in N $$ \mathcal{N} $$ = 2 supersymmetric gauged quantum mechanics

Journal of High Energy Physics
We study new Seiberg-like dualities for 1d N $$ \mathcal{N} $$ = 2 supersymmetric gauge theories — that is, supersymmetric gauged quantum mechanics — with unitary gauge group and (anti)fundamental matter in chiral and fermi multiplets, and with non-zero ...
