Varying Couplings From Orbifold GUTs
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We discuss the variation of gauge couplings in time in the framework of orbifold constructions, due to a change of the extra compact dimension's size. Models with gauge coupling un…
Determinant Calculations Using Random Walk Worldline Loops
Michael G. Schmidt, Ion-Olimpiu Stamatescu
We use statistical ensembles of worldline loops generated by random walk on hypercubic lattices to calculate matter determinants in background Yang-Mills fields.
5D SUSY Orbifold SU(6) GUT and Pseudo-Goldstone Higgs Doublets
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We construct a 5D SUSY SU(6) GUT on an $S^{(1)}/Z_2\tm Z_2'$ orbifold. The first stage of gauge symmetry breaking occurs through compactification and a specific selection of bounda…
Gauge Coupling Unification and Phenomenology of Selected Orbifold 5D N=1 SUSY Models
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We study gauge coupling unification and various phenomenological issues, such as baryon number conservation, the problem and neutrino anomalies, within SUSY 5D orbifold models.…
Semiclassical force for electroweak baryogenesis: three-dimensional derivation
Kimmo Kainulainen, Tomislav Prokopec, Michael G. Schmidt +1
We derive a semiclassical transport equation for fermions propagating in the presence of a CP-violating planar bubble wall at a first order electroweak phase transition. Starting f…
Quantum Boltzmann equations for electroweak baryogenesis including gauge fields
Kimmo Kainulainen, Tomislav Prokopec, Michael G. Schmidt +1
We review and extend to include the gauge fields our derivation of the semiclassical limit of the collisionless quantum transport equations for the fermions in presence of a CP-vio…
