Textures and Semi-Local Strings in SUSY Hybrid Inflation
Richard A. Battye, Bjorn Garbrecht, Apostolos Pilaftsis
Global topological defects may account for the large cold spot observed in the Cosmic Microwave Background. We explore possibilities of constructing models of supersymmetric F-term…
Supersymmetric Higgs Singlet Effects on B-Meson FCNC Observables at Large tan(beta)
Robert N. Hodgkinson, Apostolos Pilaftsis
Higgs singlet superfields are usually present in most extensions of the Minimal Supersymmetric Standard Model (MSSM) that address the mu-problem, such as the Next-to-Minimal Supers…
Electroweak Resonant Leptogenesis in the Singlet Majoron Model
Apostolos Pilaftsis
We study resonant leptogenesis at the electroweak phase transition in the singlet Majoron model with right-handed neutrinos. We consider a scenario, where the SM gauge group and th…
B-Meson Observables in the Maximally CP-Violating MSSM with Minimal Flavour Violation
John Ellis, Jae Sik Lee, Apostolos Pilaftsis
Additional sources of CP violation in the MSSM may affect B-meson mixings and decays, even in scenarios with minimal flavour violation (MFV). We formulate the maximally CP-violatin…
Resonant CP Violation due to Heavy Neutrinos at the LHC
Simon Bray, Jae Sik Lee, Apostolos Pilaftsis
The observed light neutrinos may be related to the existence of new heavy neutrinos in the spectrum of the SM. If a pair of heavy neutrinos has nearly degenerate masses, then CP vi…
Probing Minimal 5D Extensions of the Standard Model
Alexander Mück, Apostolos Pilaftsis, Reinhold Rückl
We analyze non-universal 5D standard model extension, where some or all of the gauge and Higgs fields propagate in a flat extra dimension, while all other degrees of freedom are lo…
