On Non-tachyonic Z_N x Z_M Orientifolds of Type 0B String Theory
K. Foerger
We study open descendants of four dimensional Z_N x Z_M orbifolds of the non-supersymmetric type 0B string theory. An exhaustive analysis shows, that using the crosscap constraint…

Higher Derivative Couplings and Heterotic-Type I Duality in Eight Dimensions
K. Foerger, S. Stieberger
We calculate F^4 and R^4T^(4g-4) couplings in d=8 heterotic and type I string vacua (with gauge and graviphoton field strengths F,T, and Riemann curvature R). The holomorphic piece…
