Анализ структуры в спектрахM μπ из распада K 0L

Summary

The physical structure in theM μπ spectra from the K 0L , attributed to the existence of neutral heavy leptons, has been analysed in a Dalitz plot of data from a spark chamber experiment which accepts all configurations of the kaon decays. The results are compatible with the existence of a neutral heavy lepton with the previously observed mass:M *μπ (429)=(0.429±0.002) GeV. There is also a compatibility between the angular distributions associated with theM *μπ in these data and those observed in other spark chamber experiments which do not accept all laboratory configurations of the kaon decays.

Riassunto

Si analizza la struttura fisica degli spettriM μπ dal K 0L , attribuiti all'esistenza di leptoni pesanti neutri, in un diagramma di Dalitz dei dati di un esperimento con camera a scintille che accetta tutte le configurazioni dei decadimenti kaonici. I risultati sono compatibili con l'esistenza di un leptone pesante neutro avente la massa precedentemente osservata:M *μπ (429)=(0.429±0.002) GeV. Vi è anche compatibilità fra le distribuzioni angolari associate conM *μπ in questi dati e quelle osservate in altri esperimenti con camere a scintilla che non accettano tutte le configurazioni nel sistema del laboratorio dei decadimenti kaonici.

Резюме

На диаграмме Далитца для данных, полученных из эксперимента в искровой камере, в котором детектировались все конфигурации каонных распадов, был проведен анализ физической структуры в спектрахM μπ из K 0L , приписанной существованию нейтральных тяжелых лептонов. Полученные результаты совместимы с существованием нейтрального тяжелого лептона с ранее наблюденной массой:M *μπ (429)=(0.429±0.002) ГэВ. Также отмечается соответствие между угловыми распределениями, связанными сM *μπ в этих данных, и распределениями, которые наблюдались в других экспериментах в искровой камере, в которых не детектировались все лабораторные конфигурации каонных распадов.
