General String Cosmologies at Order ${\alpha }^{\prime }{}^3$

Abstract

We compute the cosmological reduction of general string theories, including bosonic, heterotic and type II string theory to order ${\alpha }^{\prime 3}$, i.e., with up to eight derivatives. To this end we refine recently introduced methods that allow one to bring the reduced theory in one dimension to a canonical form with only first-order time derivatives. The resulting theories are compatible with a continuous $O(d,d,\mathbb{R})$ invariance, which in turn fixes the B-field couplings.

v2: 20 pages, important corrections that affect the coefficient $c_{4,1}$ for bosonic and heterotic string theory; all other results unchanged
