The alpha'-Expansion of Calabi-Yau Compactifications
Katrin Becker, Melanie Becker, Daniel Robbins
We consider alpha'-corrections to Calabi-Yau compactifications of type II string theory. These were discussed from the string worldsheet approach many years ago in terms of supersy…
M-theory and G_2 Manifolds
Katrin Becker, Melanie Becker, Daniel Robbins
In this talk we report on recent progress in describing compactifications of string theory and M-theory on G_2 and Spin(7) manifolds. We include the infinite set of alpha'-correcti…
Some tree-level string amplitudes in the NSR formalism
Katrin Becker, Melanie Becker, Ilarion V. Melnikov +2
We calculate tree level scattering amplitudes for open strings using the NSR formalism. We present a streamlined symmetry-based and pedagogical approach to the computations, which…
String Corrected Spacetimes and SU(N)-Structure Manifolds
Katrin Becker, Melanie Becker, Daniel Robbins
Using an effective field theory approach and the language of SU(N)-structures, we study higher derivative corrections to the supersymmetry constraints for compactifications of stri…
