Contributions of the B → B′γ process to the B → B′πγ decays

Вклады процесса B → B′г в распады B → B′πγ

Il Nuovo Cimento A (1971-1996)

Summary

The bremsstrahlung calculations for the B → B′πγ decays cannot be considered to be adequate expecially when we have high-momentum photons and when the processes which are related to the ΔS=1 B → B′γ decays followed (or preceded) by the strong emission of a pion become important. We calculate the contributions to the rate of the B → B′πγ decays from these processes as well as the espressions for the πγ angular distribution due to this mechanism as well as due to bremsstrahlung.

Riassunto

I calcoli di bremsstrahlung per i decadimenti B → B′πγ non possono considerarsi sufficienti specialmente quando si hanno fotoni ad impulso elevato e quando i processi che sono in relazione con i decadimenti B → B′γ per ΔS=1, seguiti (o preceduti) dall’emissione forte di un pione, diventano importanti. Si calcola il contributo al tasso di decadimento B → B′πγ da parte di questi processi così come l’espressione per la distribuzione angolare di πγ dovuta a questo meccanismo e al bremsstrahlung.

Реэюме

Вычисления тормоэного иэлучения для распадов B → B′πγ не могут дать адекватного описания, когда мы имеем фотоны с больщими импульсами и когда становятся важными процессы, свяэанные с распадами B → B′γ с ΔS=1, с последуюшим (или с предществуюшим) испусканием пиона. Мы вычисляем вклады зтих процессов в интенсивность распадов B → B′πγ, а также выражения для πγ углового распределения, обусловленного зтим механиэмом и тормоэным иэлучением.
