Finite deformations from a heterotic superpotential: holomorphic Chern-Simons and an L∞ algebra

A Ashmore, X De La Ossa, R Minasian… - Journal of High Energy …, 2018 - Springer
A bstract We consider finite deformations of the Hull-Strominger system. Starting from the
heterotic superpotential, we identify complex coordinates on the off-shell parameter space …

Species scale, worldsheet CFTs and emergent geometry

C Aoufia, I Basile, G Leone - arXiv preprint arXiv:2405.03683, 2024 - arxiv.org
We study infinite-distance limits in the moduli space of perturbative string vacua. The
remarkable interplay of string dualities seems to determine a highly non-trivial dichotomy …

-structure symmetries and anomalies in (1, 0) non-linear σ-models

X de La Ossa, MA Fiset - Journal of High Energy Physics, 2019 - Springer
A bstract A new symmetry of (1, 0) supersymmetric non-linear σ-models in two dimensions
with Fermi and mass sectors is introduced. It is a generalisation of the so-called special …

A Heterotic Hermitian--Yang--Mills Equivalence

G-structures and Superstrings from the Worldsheet

MA Fiset - arXiv preprint arXiv:1909.07936, 2019 - arxiv.org
$\mathcal {G} $-structures, where $\mathcal {G} $ is a Lie group, are a uniform
characterisation of many differential geometric structures of interest in supersymmetric …

(0,2) versions of exotic (2,2) GLSMs

H Parsian, E Sharpe, H Zou - International Journal of Modern …, 2018 - World Scientific
In this paper we extend work on exotic two-dimensional (2, 2) supersymmetric gauged linear
sigma models (GLSMs) in which, for example, geometries arise via nonperturbative effects …

Heterotic Non-linear Sigma Models

IV Melnikov, IV Melnikov - An Introduction to Two-Dimensional Quantum …, 2019 - Springer
In this chapter we discuss the basic features of non-linear sigma models with (0, 2)
supersymmetry. This is a large universe, and to circumscribe our explorations we mainly …
