The fate of discrete torsion on resolved heterotic Z2xZ2 orbifolds using (0,2) GLSMs

A. E. Faraggi, S. Groot Nibbelink, M. Hurtado-Heredia

This paper aims to shed light on what becomes of discrete torsion within heterotic orbifolds when they are resolved to smooth geometries. Gauged Linear Sigma Models (GLSMs) possess…

Taming Triangulation Dependence of T6/Z2xZ2 Resolutions

A. E. Faraggi, S. Groot Nibbelink, M. Hurtado-Heredia

Resolutions of certain toroidal orbifolds, like T6/Z2xZ2, are far from unique, due to triangulation dependence of their resolved local singularities. This leads to an explosion of…

Constraint on Spinor-Vector Dualities in Six Dimensions

A. E. Faraggi, S. Groot Nibbelink, M. Hurtado-Heredia

Imprints of spinor-vector dualities have been uncovered in various string constructions. They are typically induced by changing certain free general GSO phases in the underlying st…

Uncovering a Spinor-Vector Duality on a Resolved Orbifold

A. E. Faraggi, S. Groot Nibbelink, M. Hurtado-Heredia

Spinor-vector dualities have been established in various exact string realisations like orbifold and free fermionic constructions. This paper aims to investigate possibility of hav…

A Worldsheet Perspective on Heterotic T-Duality Orbifolds

Stefan Groot Nibbelink

Asymmetric heterotic orbifolds are discussed from the worldsheet perspective. Starting from Buscher's gauging of a theory of D compact bosons the duality covariant description of T…

Nonexistence of locally but not globally supersymmetric orbifolds

Stefan Groot Nibbelink

Motivated by the smallness of the cosmological constant we investigate whether it is possible to have vanishing one-loop heterotic string partition functions for six-dimensional no…

T-duality orbifolds of heterotic Narain compactifications

Stefan Groot Nibbelink, Patrick K. S. Vaudrevange

To obtain a unified framework for symmetric and asymmetric heterotic orbifold constructions we provide a systematic study of Narain compactifications orbifolded by finite order T-d…
