Small gauge transformations and universal geometry in heterotic theories
Jock McOrist, Roberto Sisca
The first part of this paper describes in detail the action of small gauge transformations in heterotic supergravity. We show a convenient gauge fixing is `holomorphic gauge' toget…

The Universal Geometry of Heterotic Vacua
Philip Candelas, Xenia de la Ossa, Jock McOrist +1
We consider a family of perturbative heterotic string backgrounds. These are complex threefolds X with c_1 = 0, each with a gauge field solving the Hermitian Yang-Mill's equations…

Notes on Theta Dependence in Holographic Yang-Mills
Francesco Bigazzi, Aldo L. Cotrone, Roberto Sisca
Effects of the theta parameter are studied in Witten's model of holographic 4d Yang-Mills, where theta is the coefficient of the CP-breaking topological term. First, the gravity ba…
