The LeptonS Laboratory is part of the Lepton Group of the Department of Cosmic Rays and Chronology. The focus of this is to study particles classified as leptons (they have spin 1/2 and whole charge), mainly neutrino. This is the lightest particle ever detected, after the photon with null resting mass, it is not yet known exactly the value of its mass, but there is an upper limit to it.
Neutrino has no load and interacts very little with matter, which makes it difficult to detect. Despite this, it is possible to detect it, since they are very abundant. The main sources we can find is through the Earth’s own radioactivity, nuclear reactors, cosmic events and the Sun (65 billion neutrinos reach each cm2 of the Earth per second).
Large experiments around the planet study more efficient ways to detect them, the Lepton Group works together with these. Even with the largest neutrino detection experiment, Deep Underground Neutrino Experiment (DUNE).
This is still under construction and testing, the main objectives they seek to achieve are: violation of CP symmetry, proton decay, detection of neutrinos produced by a stellar collapse (supernova neutrinos) and determine the hierarchy of neutrino masses (muonic, taunic and electronic).
More than 1000 researchers contribute to this project being carried out.
