Summary
We present numerical estimates for the radiative corrections to the decays L∓ → e∓νeνL, μ∓ νμνL in the context of aV ±A interaction. The radiative corrections change the Michel parameter appreciably from its bareV ±A value, for the decay L∓ → e∓νeνL, and have a measurable effect on the electron energy spectrum.
Riassunto
Si presentano stime numeriche per le correzioni radiative dei decadimenti L∓ → e∓νeνL, μ∓ νμν L nel contesto dell’interazioneV ±A. Le correzioni radiative cambiano in maniera apprezzabile il parametro di Michel dal suo semplice valore secondoV ±A, per il decadimento L∓ → e∓νeνL, ed hanno un effetto misurabile sullo spettro dell’energia dell’elettrone.
Реэюме
Предлагаются численные оценки для радиационных поправок к распадам L∓ → e∓νeνL, μ∓ νμν L в контексте УА вэаимодействия. Радиационные поправки сушественно иэменяют параметр Мищеля по сравнению с голымV ±А эначением для распада L∓ → e∓νeνL и приводят к наблюдаемому зффекту в знергетическом спектре злектронов.
