A model of superluminal neutrinos
D. Marfatia, H. Päs, S. Pakvasa +1
Motivated by the tentative observation of superluminal neutrinos by the OPERA experiment, we present a model of active-sterile neutrino oscillations in which sterile neutrinos are…
Baryon asymmetry of the universe and new neutrino states
Sebastian Hollenberg, Heinrich Päs, Dario Schalla
The presence of additional neutrino states with masses in the GeV range is allowed by electro-weak precision observables. However, these additional states can lead to lepton number…
R-Parity violating flavor symmetries, recent neutrino data and absolute neutrino mass scale
Gautam Bhattacharyya, Heinrich Päs, Daniel Pidt
We study the role of a very general type of flavor symmetry in controlling the strength of R-parity violation in supersymmetric models. We assume that only leptons are charged unde…
Fourth Generation Majorana Neutrinos
Alexander Lenz, Heinrich Päs, Dario Schalla
We investigate the possibility of a fourth sequential generation in the lepton sector. Assuming neutrinos to be Majorana particles and starting from a recent - albeit weak - eviden…
Adiabatic & non-adiabatic perturbation theory for coherence vector description of neutrino oscillations
Sebastian Hollenberg, Heinrich Päs
The standard wave function approach for the treatment of neutrino oscillations fails in situations where quantum ensembles at a finite temperature with or without an interacting ba…
