Exotic properties of neutrinos using effective Lagrangians and specific models
Alberto Aparici
This doctoral dissertation presents several works on nonstandard properties of neutrinos exploiting the synergies between effective field theory and models. The phenomena are first…
Right-handed neutrino magnetic moments
Alberto Aparici, Kyungwook Kim, Arcadi Santamaria +1
We consider the most general dimension-five effective Lagrangian that can be built using only Standard Model fields plus right-handed neutrinos, and find that there exists a term t…
Neutrinoless double decay with small neutrino masses
F. del Águila, A. Aparici, S. Bhattacharya +2
If the only contribution to neutrinoless double beta decay (NLDBD) are neutrino masses its discovery may be very difficult, especially if neutrinos present a normal hierarchy spect…
Effective Lagrangian approach to neutrinoless double beta decay and neutrino masses
Francisco del Aguila, Alberto Aparici, Subhaditya Bhattacharya +2
Neutrinoless double beta () decay can in general produce electrons of either chirality, in contrast with the minimal Standard Model (SM) extension with only the addition of t…
On the nature of the fourth generation neutrino and its implications
Alberto Aparici, Juan Herrero-García, Nuria Rius +1
We consider the neutrino sector of a Standard Model with four generations. While the three light neutrinos can obtain their masses from a variety of mechanisms with or without new…
A realistic model of neutrino masses with a large neutrinoless double beta decay rate
Francisco del Aguila, Alberto Aparici, Subhaditya Bhattacharya +2
The minimal Standard Model extension with the Weinberg operator does accommodate the observed neutrino masses and mixing, but predicts a neutrinoless double beta () decay rat…
Implications of new generations on neutrino masses
A. Aparici, J. Herrero-Garcia, N. Rius +1
We explore the possible implications that new families, that are being searched for at the LHC, would have on neutrino masses. In particular, we have explored the possibility that…
Can new generations explain neutrino masses?
A. Aparici, J. Herrero-Garcia, N. Rius +1
In this talk we explore the possibility that the smallness of the observed neutrino masses is naturally understood in a modified version of the standard model with N extra generati…
Neutrino masses from new generations
Alberto Aparici, Juan Herrero-García, Nuria Rius +1
We reconsider the possibility that Majorana masses for the three known neutrinos are generated radiatively by the presence of a fourth generation and one right-handed neutrino with…
A model for right-handed neutrino magnetic moments
Alberto Aparici, Arcadi Santamaria, Jose Wudka
A simple extension of the Standard Model providing Majorana magnetic moments to right-handed neutrinos is presented. The model contains, in addition to the Standard Model particles…
Right-handed neutrino magnetic moments
Alberto Aparici, Kyungwook Kim, Arcadi Santamaria +1
We discuss the phenomenology of the most general effective Lagrangian, up to operators of dimension 5, build with standard model fields and interactions including right-handed neut…
