Summary
A test of the ΔS=ΔQ selection rule in K 0μ3 decay was performed using optical spark chambers. K0-mesons were produced by 3 GeV/c π− in the reaction π−p→ΛK0. 100 events with proper decay times between 0.5 and 6.5 K 0 s lifetimes were analysed to give a ratio of the ΔS=−ΔQ to ΔS=ΔQ amplitudes Rex′=0.04 +0.10−0.13 , Imx′=0.12 +0.17−0.16 .
Riassunto
Si è eseguita una verifica della regola di selezione ΔS=ΔQ nel decadimento K 0μ3 usando camere a scintille ottiche. I mesoni K0 erano prodotti da π− di 3 GeV/c nella reazione π−→ΛK0. Si sono analizzati 100 eventi con tempi di decadimento propri compresi tra 0.5 e 6.5 vite medie del K 0 s ottenendo un rapporto delle ampiezze ΔS=−ΔQ e ΔS=ΔQ Rex′=0.04 +0.10−0.13 , Imx′=0.12 +0.17−0.16 .
Резюме
С помощью оптических искровых камер была проведена проверка правила отбора ΔS=ДQ в распаде K 0μ3 . K0-мезоны рождались π− мезонами с импульсом 3 ГэВ/с в реакции π−p→ΛK0. Был проведен анализ 100 событий с собственными временами распада в интервале от 0.5 до 6.5 времен жизни K 0 s . Анализ дал следующие значения для отношения амплитуд ΔS=−ΔQ и ΔS=ΔQ: Rex′=0.04 +0.10−0.13 , Imx′=0.12 +0.17−0.16 .
