Helicity calculations for heavy-lepton production and cascade decay

Спиральные вычисления для рождения и каскадного распада тяжелых лептонов

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We calculate the transition probabilities for neutrino production and cascade decay sequences of charged heavy leptons, using a helicity formalism in which the separate stages are factored. This is an alternative to computer calculations of gamma-matrix traces, which sometimes lead to very cumbersome expressions for long decay chains.

Riassunto

Si calcolano le probabilità di transizione per la produzione neutrinica e le sequenze del decadimento a cascata dei leptoni pesanti carichi, per mezzo di un formalismo di elicità in cui i diversi stadi sono fattorizzati. Questa è un'alternativa a calcoli per mezzo del calcolatore di tracce di matrici gamma che qualche volta portano a espressioni complesse per lunghe catene di decadimento.

Резюме

Мы вычисляем вероятности переходов для рождения и последовательности каскадных распадов заряженных тяжелых лептонов, используя спиральный формализм, в котором отдельные стадии факторизуются. Зтот подход представляет альтернативу компьютерным вычислениям следов гамма-матриц, которые отчасти приводят к очень громоздким выражениям для длиных цепочек распадов.
