Will A New Neutrino Change The Standard Model?
Summary
This episode explores the potential discovery of sterile neutrinos, particles that interact only via gravity and could expand the Standard Model. The host explains the physics of chirality and the MiniBoone experiment, which detected an excess of electron neutrinos suggesting sterile neutrino involvement. While the combined data from MiniBoone and LSND indicates a significant signal, the host notes conflicts with other measurements like IceCube and Planck satellite data, leaving the finding open to further investigation.
