The physics of neutrinos is studied using different sources such as reactors, accelerators and radioactive sources.
The objectives of these experiments are:
- to measure all neutrino oscillation parameters by varying their energies and oscillation distance and measure their mass. These measurements could be related to phenomena beyond the standard particle physics model: for example new interactions, or the existence of new particles.
- to precisely measure the difference in propagation of neutrinos and antineutrinos in order to quantify the violation of charge-parity symmetry (CP) by neutrinos. This could shed light on the origin of the asymmetry between matter and antimatter in the Universe.
- to measure a very rare beta disintegration, called double beta without neutrino (named "ββ0ν"), which would prove that the neutrino could have a different nature from the other particles of matter and be identical to its own antiparticle.
