Supersymmetry, T-duality and heterotic α′-corrections

Journal of High Energy Physics, 2021
Higher-derivative interactions and transformation rules of the fields in the effective field theories of the massless string states are strongly constrained by space-time symmetries and dualities. Here we use an exact formulation of ten dimensional N $$ \

S-duality and supersymmetry on curved manifolds

Journal of High Energy Physics, 2020
We perform a systematic study of S-duality for N $$ \mathcal{N} $$ = 2 supersymmetric non-linear abelian theories on a curved manifold. Localization can be used to compute certain supersymmetric observables in these theories.

Perturbative higher-derivative terms in N $$ \mathcal{N} $$ = 6 asymmetric orbifolds

Journal of High Energy Physics, 2022
We analyse the perturbative four-point amplitudes in the simplest string theory examples of T-fold backgrounds, which enjoy N $$ \mathcal{N} $$ = 6 supersymmetries in four dimensions.

Deformation of d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities breaks nonlinear local supersymmetry

Journal of High Energy Physics, 2023
We study d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities and their deformation via candidate counterterms, with the purpose to absorb UV divergences. We generalize the earlier studies of deformation and twisted self-duality constraint to the case with ...

Superconformal duality-invariant models and N $$ \mathcal{N} $$ = 4 SYM effective action

Journal of High Energy Physics, 2021
We present N $$ \mathcal{N} $$ = 2 superconformal U(1) duality-invariant models for an Abelian vector multiplet coupled to conformal supergravity. In a Minkowski background, such a nonlinear theory is expected to describe (the planar part of) the low ...

Worldsheet (anti)instanton bound states in type II on T 2

Journal of High Energy Physics, 2020
The 1/8 BPS D 6ℛ4 coupling in type II string theory compactified on T 2 receives contributions from worldsheet instantons and anti-instantons wrapping the T 2, up to genus three in string perturbation theory.

On N $$ \mathcal{N} $$ = 4 supersymmetry enhancements in three dimensions

Journal of High Energy Physics, 2023
We introduce a class of 3d theories consisting of strongly-coupled N $$ \mathcal{N} $$ = 4 systems coupled to N $$ \mathcal{N} $$ = 3 Chern-Simons gauge multiplets, which exhibit N $$ \mathcal{N} $$ = 4 enhancements when a peculiar condition on the Chern-

T-duality transformations for the NS5-brane along angular directions

Journal of High Energy Physics, 2018
In this note we study T-duality transformations for the NS5-brane and its orbifolds along angular directions. We identify a geometric charge for these configurations and show that it is interchanged with the H-flux under T-duality. We furthermore perform

3d N $$ \mathcal{N} $$ = 3 generalized Giveon-Kutasov duality

Journal of High Energy Physics, 2022
We generalize the Giveon-Kutasov duality for the 3d N $$ \mathcal{N} $$ = 3 U(N) k,k+nN Chern-Simons matter gauge theory with F fundamental hypermultiplets by introducing SU(N) and U(1) Chern-Simons levels differently.

Boundary confining dualities and Askey-Wilson type q-beta integrals

Journal of High Energy Physics, 2023
We propose confining dualities of N $$ \mathcal{N} $$ = (0, 2) half-BPS boundary conditions in 3d N $$ \mathcal{N} $$ = 2 supersymmetric SU(N), USp(2n) and SO(N) gauge theories.
