What do we Research on?

PheNUmenal worked in the area of Theoretical Particle Physics, trying to solve the mysteries that our best theory, the Standard Model of Particle Phycics, can't explain. 

ā€‹ā€‹

One of these mysteries is related to neutrinos, which actually hides several questions: where are their masses coming from? what is their actual nature? are there new neutrinos? are they related to other unsolved mysteries like dark matter or the origin of the matter itself?

PheNUmenal focused on neutrino physics, but also used effective field theories to explore more general scenarios. Despite being a theoretical project, the approach to these questions was phenomenological, as it also wondered which experiment would probe the new models we propose. 

 

Here you will find the complete list of publications, fully available also in the open repository arXiv, as well as a list of contributions to international conferences and workshops.
