A Z2xZ2 standard model
Michael Blaszczyk, Stefan Groot Nibbelink, Michael Ratz +3
We present a Z_2 x Z_2 orbifold compactification of the E_8 x E_8 heterotic string which gives rise to the exact chiral MSSM spectrum. The GUT breaking SU(5) to SU(3)_C x SU(2)_L x…
Local Grand Unification and String Theory
Hans Peter Nilles, Saul Ramos-Sanchez, Patrick K. S. Vaudrevange
The low energy effective action of string theory depends strongly on the process of compactification and the localization of fields in extra dimensions. Explicit string constructio…
Accions
Kang-Sin Choi, Hans Peter Nilles, Saul Ramos-Sanchez +1
Axion fields provide the most elegant solution to the strong CP problem. In string compactifications it is difficult to obtain an axion whose decay constant is consistent with curr…
Heterotic Z6-II MSSM Orbifolds in Blowup
Stefan Groot Nibbelink, Johannes Held, Fabian Ruehle +2
Heterotic orbifolds provide promising constructions of MSSM-like models in string theory. We investigate the connection of such orbifold models with smooth Calabi-Yau compactificat…
