The international collaboration developed by the MicroBoone experiment, which has the participation of the researcher of the Department of Theoretical Physics and Cosmos of the University of Granada Diego García Gámez, has announced the discarding, with 95% certainty, of the idea that a single "sterile neutrino" is the cause of the anomalies detected for decades in the behavior of these particles.
Fermilab experiment finds no evidence for a fourth neutrino, ending a long-debated theory
For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known types: electron, muon and tau. That shape-shifting is supposed to be fully explained by the Standard Model of particle physics. Yet a handful of experiments kept hinting the story might not be complete. Those earlier measurements suggested neutrino…
