Moduli Space of Torsional Manifolds
Melanie Becker, Li-Sheng Tseng, Shing-Tung Yau
We characterize the geometric moduli of non-Kaehler manifolds with torsion. Heterotic supersymmetric flux compactifications require that the six-dimensional internal manifold be ba…
Anomaly Cancellation and Smooth Non-Kahler Solutions in Heterotic String Theory
Katrin Becker, Melanie Becker, Ji-Xiang Fu +2
We show that six-dimensional backgrounds that are T^2 bundle over a Calabi-Yau two-fold base are consistent smooth solutions of heterotic flux compactifications. We emphasize the i…
Heterotic Flux Compactifications and Their Moduli
Katrin Becker, Li-Sheng Tseng
We study supersymmetric compactification to four dimensions with non-zero H-flux in heterotic string theory. The background metric is generically conformally balanced and can be co…
SL(2,Z) Multiplets in N=4 SYM Theory
Li-Sheng Tseng
We discuss the action of SL(2,Z) on local operators in D=4, N=4 SYM theory in the superconformal phase. The modular property of the operator's scaling dimension determines whether…
