Anirban Basu, Savdeep Sethi
TL;DR
This paper demonstrates that (0,2) gauged linear sigma models in two dimensions remain stable against instanton-induced superpotentials, supported by specific examples and a general proof using the Konishi anomaly.
Contribution
It provides the first comprehensive proof that (0,2) linear sigma models are stable against world-sheet instanton effects, using the Konishi anomaly.
Findings
Examples showing stability of models
General proof based on Konishi anomaly
Models are not destabilized by instantons
Abstract
We argue that two-dimensional (0,2) gauged linear sigma models are not destabilized by instanton generated world-sheet superpotentials. We construct several examples where we show this to be true. The general proof is based on the Konishi anomaly for (0,2) theories.
