On the Effective Field Theory of Heterotic Vacua

Understand

The effective field theory of heterotic vacua that realise $\mathbb{R}^{3,1}$ preserving $\mathcal{N} =1$ supersymmetry are studied.

• The vacua in question admit large radius limits taking the form $\mathbb{R}^{3,1}\times {X}$ , with ${X}$ a smooth three-fold with vanishing first Chern class and a stable holomorphic gauge bundle $\mathcal{E}$.
• In a previous paper we calculated the kinetic terms for moduli, deducing the moduli metric and Kahler potential.
• In this paper, we compute the remaining couplings in the effective field theory, correct to first order in alpha prime.
