Worldlines on Orbifolds and the Fayet-Iliopoulos Term
Felix Bruemmer, Michael G. Schmidt, Zurab Tavartkiladze
We adapt ``string-inspired'' worldline techniques to one-loop calculations on orbifolds, in particular on the orbifold. Our method also allows for the treatment of brane-…
Axial Currents from CKM Matrix CP Violation
T. Konstandin
The first principle derivation of kinetic transport equations suggests that a CP-violating mass term during the electroweak phase transition can induce axial vector currents. Since…
Kinetic description of fermion flavor mixing and CP-violating sources for baryogenesis
Thomas Konstandin, Tomislav Prokopec, Michael G. Schmidt
We derive transport equations for fermionic systems with a space-time dependent mass matrix in flavor space allowing for complex elements leading to CP violation required for elect…
Coherent Baryogenesis and Nonthermal Leptogenesis: A comparison
Bjorn Garbrecht, Tomislav Prokopec, Michael G. Schmidt
We present a new mechanism for baryogenesis: at preheating after inflation fermions acquire a varying mass by their coupling to a time dependent field. Their CP-violating mass matr…
(BPS) Fayet-Iliopoulos Terms in 5D Orbifold SUGRA
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We discuss Fayet-Iliopoulos terms in the context of five-dimensional supergravity compactified on an orbifold. For this purpose we use our superfield formulation of the off-shell 5…
Superfield Approach to 5D Conformal SUGRA and the Radion
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We propose that the radion chiral supermultiplet of five dimensional compactified supergravity is obtained by reduction of the graviphoton gauge multiplet to N=1 superfields in the…
Transport equations for chiral fermions to order \hbar and electroweak baryogenesis: Part II
T. Prokopec, M. G. Schmidt, S. Weinstock
This is the second in a series of two papers. While in Paper I we derive semiclassical Boltzmann transport equations and study their flow terms, here we address the collision terms…
