Quest for CP violation in the neutrino sector
The smoke is now curling up From the peak of Asama.1
Neutrinos have had a most remarkable career already. They were first postulated by Pauli at the VII Solvay Congress in 1933 – to less than universal acclaim – as a theoretical crutch to balance energy, momentum and angular momentum in β decay: n → pe−.... At least one theorist of towering reputation – Bohr – was more inclined to limit the validity of energy conservation in the nuclear domain. It was not until 1953 that the existence of neutrinos was verified by Reines and Cowan . In 1956/57 neutrinos (through their handedness) played the central role in the unfolding drama of the demise of parity as an absolute symmetry of nature. ...
