What is the weak charge of the electron?

Что представляет слабый эаряд злектрона?

Summary

The experimental results on\(\bar \nu _\mu \)-electron scattering, when interpreted withinSU 2×U 1 theories, put severe constraints on the weak charge of the right-handed electron. Under very general assumptions it is shown that the casesI weak3 (e −R )=0 or − 1/2 are possible. The caseI weak3 (e −R )=+1/2 is found to be unlikely. All other assignments for e −R are excluded. Consequences for parity violation in atomic physics are discussed.

Riassunto

I risultati sperimentali sullo scattering elettrone-\(\bar \nu _\mu \), se interpretati nell’ambito delle teorieSU 2 ×U 1, pongono severi vincoli sulla carica debole dell’elettrone destrogiro. In base a ipotesi molto generali, si mostra che i casiI weak3 (e −R )=0 o=1/2 sono possibili. Si trova invece che il casoI weak3 (e −R )=+1/2 è improbabile. Tutte le altre possibilità per e −R sono escluse. Si discutono le conseguenze per la violazione della parità in fisica atomica.

Реэюме

Экспериментальные реэультаты по рассеяния\(\bar \nu _\mu \)-e, которые интерпретируются в рамкахSU 2×U 1 теории, накладывают жесткие ограничения на слабый эаряд правовинтового злектрона. При очень обших предположениях покаэывается, что случаиI слаб3 (e −R =0 или − 1/2 являются воэможными. Получено, что случайI слаб3 (e −R =+1/2 является маловероятным. Все другие эначения для e −R исключаются. Обсуждаются следствия нарущения четности в атомной фиэике.
