Asymmetric Orbifold Models of Non-supersymmetric Heterotic Strings
Toshihiro Sasada
We investigate asymmetric orbifold models constructed from non-supersymmetric heterotic strings. We systematically classify the asymmetric orbifold models with standard embeddings…
Space-time Supersymmetry in Asymmetric Orbifold Models
Toshihiro Sasada
We study the condition for the appearance of space-time supercharges in twisted sectors of asymmetric orbifold models. We present a list of the asymmetric -orbifold models whi…
Fermion Currents on Asymmetric Orbifolds
Toshihiro Sasada
We study whether orbifold models are equivalently rewritten into torus models in the case of fermionic string theories. It is pointed out that symmetric orbifold models cannot be r…
String Theories on the Asymmetric Orbifolds with Twist-Untwist Intertwining Currents
Y. Imamura, M. Sakamoto, T. Sasada +1
We give various examples of asymmetric orbifold models to possess intertwining currents which convert untwisted string states to twisted ones, and vice versa, and see that such asy…
