Light Sterile Neutrino in the Minimal Extended Seesaw
He Zhang
Motivated by the recent observations on sterile neutrinos, we present a minimal extension of the canonical type-I seesaw by adding one extra singlet fermion. After the decoupling o…
Renormalization Group Running of the Neutrino Mass Operator in Extra Dimensions
Mattias Blennow, Henrik Melbeus, Tommy Ohlsson +1
We study the renormalization group (RG) running of the neutrino masses and the leptonic mixing parameters in two different extra-dimensional models, namely, the Universal Extra Dim…
Threshold effects on renormalization group running of neutrino parameters in the low-scale seesaw model
Johannes Bergstrom, Tommy Ohlsson, He Zhang
We show that, in the low-scale type-I seesaw model, renormalization group running of neutrino parameters may lead to significant modifications of the leptonic mixing angles in view…
Non-unitarity of the leptonic mixing matrix in the TeV-scale type-I seesaw model
Tommy Ohlsson, Christoph Popa, He Zhang
The non-unitarity effects in the leptonic flavor mixing are regarded as one of the generic features of the type-I seesaw model. Therefore, we explore these effects in the TeV-scale…
Renormalization group running of neutrino parameters in the inverse seesaw model
Johannes Bergstrom, Michal Malinsky, Tommy Ohlsson +1
We perform a detailed study of the renormalization group equations in the inverse seesaw model. Especially, we derive compact analytical formulas for the running of the neutrino pa…
Signatures from an extra-dimensional seesaw model
Mattias Blennow, Henrik Melbeus, Tommy Ohlsson +1
We study the generation of small neutrino masses in an extra-dimensional model, where right-handed neutrinos are allowed to propagate in the extra dimension, while the Standard Mod…
