The alpha-prime stretched horizon in the Heterotic string
Ghasem Exirifard
The linear alpha-prime corrections and the field redefinition ambiguities are studied for half-BPS singular backgrounds representing a wrapped fundamental string. It is showed that…

Quadratic alpha' corrections to T-duality
Ghasem Exirifard
The quadratic alpha' corrections to the two-dimensional black hole and to its T-dual are calculated. These backgrounds are used to write the covariant form of the quadratic alpha'…

Two and three loop alpha' corrections to T-duality: Kasner and Schwarzschild
Ghasem Exirifard, Martin O'Loughlin
Two and three loop alpha' corrections are calculated for Kasner and Schwarzschild metrics, and their T-duals, in the bosonic string theory. These metrics are used to obtain the two…
