Standard Model bundles of the heterotic string
We show how to construct supersymmetric three-generation models with gauge group and matter content of the Standard Model in the framework of non-simplyconnected elliptically fibered Calabi-Yau manifolds Z. The elliptic fibration on a cover Calabi-Yau, where the model has 6 generations of SU(5) and the bundle is given via the spectral cover description, has a second section leading to the neede...
متن کاملThe Standard-Model Extension and Gravitational Tests
The Standard-Model Extension (SME) provides a comprehensive effective field-theory framework for the study of CPT and Lorentz symmetry. This work reviews the structure and philosophy of the SME and provides some intuitive examples of symmetry violation. The results of recent gravitational tests performed within the SME are summarized including analysis of results from the Laser Interferometer G...
متن کاملA Sinister Extension of the Standard Model
This paper describes work done in collaboration with Andy Cohen. In our model, ordinary fermions are accompanied by an equal number ‘terafermions.’ These particles are linked to ordinary quarks and leptons by an unconventional CP’ operation, whose soft breaking in the Higgs mass sector results in their acquiring large masses. The model leads to no detectable strong CP violating effects, produce...
متن کاملA Stueckelberg Extension of the Standard Model
An extension of the standard model of electro-weak interactions by an extra abelian gauge boson is given, in which the extra gauge boson and the hypercharge gauge boson both couple to an axionic scalar in a form that leads to a Stueckelberg mass term. The theory leads to a massive Z whose couplings to fermions are uniquely determined and suppressed by small mixing angles. Such a Z could have a ...
