Do Incomplete GUT Multiplets Always Spoil Unification?
Akin Wingerter
We consider a new class of light vectorlike exotics with fractional electric charge which do not come in complete representations of a grand unified gauge group, and are neverthele…
The Heterotic Road to the MSSM with R parity
Oleg Lebedev, Hans Peter Nilles, Stuart Raby +4
In a previous paper, referred to as a "Mini-Landscape" search, we explored a "fertile patch" of the heterotic landscape based on a Z6-II orbifold with SO(10) and E6 local GUT struc…
Can String Theory Predict the Weinberg Angle?
S. Raby, A. Wingerter
We investigate whether the hypercharge assignments in the Standard Model can be interpreted as a hint at Grand Unification in the context of heterotic string theory. To this end, w…
Gauge coupling unification and light Exotica in String Theory
Stuart Raby, Akin Wingerter
In this letter we consider the consequences for the LHC of light vector-like exotica with fractional electric charge. It is shown that such states are found in orbifold constructio…
