String-derived MSSM vacua with residual R symmetries
Rolf Kappl, Bjoern Petersen, Stuart Raby +3
Recently it was shown that there is a unique Z_4^R symmetry for the MSSM which allows the Yukawa couplings and dimension five neutrino mass operator, forbids the mu term and commut…
A unique Z_4^R symmetry for the MSSM
Hyun Min Lee, Stuart Raby, Michael Ratz +4
We consider the possible anomaly free Abelian discrete symmetries of the MSSM that forbid the mu-term at perturbative order. Allowing for anomaly cancellation via the Green-Schwarz…
Proton Hexality in Local Grand Unification
Stefan Forste, Hans Peter Nilles, Saul Ramos-Sanchez +1
Proton hexality is a discrete symmetry that avoids the problem of too fast proton decay in the supersymmetric extension of the standard model. Unfortunately it is inconsistent with…
Heterotic MSSM on a Resolved Orbifold
Michael Blaszczyk, Stefan Groot Nibbelink, Fabian Ruehle +2
We construct an MSSM with three generations from the heterotic string compactified on a smooth 6D internal manifold using Abelian gauge fluxes only. The compactification space is o…
An involuted orbifold MSSM
Patrick K. S. Vaudrevange
A compactification of the E_8 x E_8 heterotic string on a Z_2 x Z_2 orbifold equipped with an additional freely acting involution is presented. This model reproduces the exact chir…
