Will A New Neutrino Change The Standard Model?

The video explores the concept of sterile neutrinos, a potential new particle outside the Standard Model. It discusses their significance in particle physics, their potential role as dark matter, and their influence on the early universe. The video explains the challenges in detecting sterile neutrinos, as they do not interact via the weak nuclear force. It covers the Standard Model, antimatter, chirality, and neutrino oscillation. The MiniBooNE experiment's findings suggest an excess of electron neutrinos, hinting at sterile neutrinos, but conflicting evidence from other experiments leaves the discovery uncertain.
