Study of the Neutrino Oscillation in the context of Standard and Non-Standard Physics

Neutrino oscillation is an experimentally established phenomenon that requires neutrinos to be massive, which is why the 2015 Nobel Prize in Physics was awarded to the leaders of the collaborations that made the first measurements. On the other hand, the Standard Model of particles, despite being a successful theory that incorporates the known interactions (except gravity) and that has successfully responded to an enormous amount of experimental tests, does not incorporate massive neutrinos. Therefore, neutrinos are one of the few experimental pieces of evidence implicating Physics beyond the Standard Model (or Non-Standard physics). The main objective of this project is to statistically combine the data from the most relevant experiments, which will be called "global neutrino adjustment", to determine the parameters that define the oscillation mechanism. Also, a second objective, no less important, is to study non-standard physics from its impact on neutrino oscillations. Typical examples of non-standard studies are the so-called "non-standard neutrino interactions", effects of having an extra neutrino, deviation from the unitarity of the mixing matrix, among others that can be motivated theoretically. This last objective can be carried out with data from experiments that are currently working, to produce limits, or with future experiments such as DUNE to see the feasibility of having non-standard physics signals, under study, in some of the detectors of the experiment. There are currently a considerable number of oscillation experiments taking data and others being planned, so it is a very active field of research.

Study neutrino oscillations in the context of Standard and Non-Standard Physics both with data from the most relevant current experiments and with information from simulations of expected events in the detectors of future experiments.

With this project we hope to contribute to the determination of the oscillation parameters, which has a great impact on the neutrino community. Also, we will contribute with sensitivity studies that future experiments may have regarding the free parameters that come from non-standard physics models (theoretical or phenomenologically motivated) from their impact on neutrino oscillations. This last type of study is of great interest to experimental collaborations.
