On Tachyons in Generic Orbifolds of C and Gauged Linear Sigma Models

Abstract

We study some aspects of Gauged Linear Sigma Models corresponding to orbifold singularities of the form C/Γ, for r = 2, 3 and Γ = Zn and Zn × Zm. These orbifolds might be tachyonic in general. We compute expressions for the multi parameter sigma model Lagrangians for these orbifolds, in terms of their toric geometry data. Using this, we analyze some aspects… (More)
