Radiative corrections to the leptonic decays of the charged heavy leptons

Радиационные поправки к лептонным распадам тяжелых эаряженных лентонов

Summary

We present numerical estimates for the radiative corrections to the decays L → eνeνL, 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 → eνeνL, and have a measurable effect on the electron energy spectrum.

Riassunto

Si presentano stime numeriche per le correzioni radiative dei decadimenti L → eνeνL, 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 → eνeνL, ed hanno un effetto misurabile sullo spettro dell’energia dell’elettrone.

Реэюме

Предлагаются численные оценки для радиационных поправок к распадам L → eνeνL, μ νμν L в контексте УА вэаимодействия. Радиационные поправки сушественно иэменяют параметр Мищеля по сравнению с голымV ±А эначением для распада L → eνeνL и приводят к наблюдаемому зффекту в знергетическом спектре злектронов.
