Non-unitary Leptonic Mixing and Leptogenesis
Stefan Antusch, Steve Blanchet, Mattias Blennow +1
We investigate the relation between non-unitarity of the leptonic mixing matrix and leptogenesis. We discuss how all parameters of the canonical type-I seesaw mechanism can, in pri…
Neutrinos from Kaluza-Klein dark matter in the Sun
Mattias Blennow, Henrik Melbeus, Tommy Ohlsson
We investigate indirect neutrino signals from annihilations of Kaluza-Klein dark matter in the Sun. Especially, we examine a five- as well as a six-dimensional model, and allow for…
General bounds on non-standard neutrino interactions
Carla Biggio, Mattias Blennow, Enrique Fernandez-Martinez
We derive model-independent bounds on production and detection non-standard neutrino interactions (NSI). We find that the constraints for NSI parameters are around O(10^{-2}) to O(…
Probing non-unitary mixing and CP-violation at a Neutrino Factory
Stefan Antusch, Mattias Blennow, Enrique Fernandez-Martinez +1
A low energy non-unitary leptonic mixing matrix is a generic feature of many extensions of the Standard Model. In such a case, the task of future precision neutrino oscillation exp…
Neutrino oscillation parameter sampling with MonteCUBES
Mattias Blennow, Enrique Fernandez-Martinez
We present MonteCUBES ("Monte Carlo Utility Based Experiment Simulator"), a software package designed to sample the neutrino oscillation parameter space through Markov Chain Monte…
Loop bounds on non-standard neutrino interactions
Carla Biggio, Mattias Blennow, Enrique Fernandez-Martinez
We reconsider the bounds on non-standard neutrino interactions with matter which can be derived by constraining the four-charged-lepton operators induced at the loop level. We find…
Non-standard interaction effects on astrophysical neutrino fluxes
Mattias Blennow, Davide Meloni
We investigate new physics effects in the production and detection of high energy neutrinos at neutrino telescopes. Analysing the flavor ratios ϕ_μ/ϕ_τand ϕ_μ/(ϕ_τ+ϕ_e), we find th…
