Production of Heavy Flavours with Associated Jets at HERA
(2007)
Inclusive cross-sections for the production of open beauty and charm in ep collisions at HERA recorded with the ZEUS detector in the years 1996-2000 are measured. The data is restricted to photoproduction processes, i.e. ...
Local Gauge Coupling Running in Supersymmetric Gauge Theories on Orbifolds
(2007)
By extending Feynman's path integral calculus to fields which respect orbifold boundary conditions we provide a straightforward and convenient framework for loop calculations on orbifolds. We take advantage of this general ...
Towards Low Energy Physics from the Heterotic String
(2008)
We investigate orbifold compactifications of the heterotic string, addressing in detail their construction, classification and phenomenological potential. Based on the insight gained from grand unification theories, we ...
Aspects of Grand Unification in Higher Dimensions
(2005)
We consider various aspects of string phenomenology in the context of heterotic orbifold constructions, where special emphasis is laid on the connection between GUT models in extra dimensions and their relation to string ...
Charm Production in Charged Current Deep Inelastic e+p Scattering at HERA
(2006)
The measurement of charm production in charged current deep inelastic positron-proton scattering is investigated with the ZEUS detector at the HERA collider. The data used has been collected from 1995 to 2000, corresponding ...
