Summary
The reactions K−p→K−pπ;−π;+, \(\bar K\) 0pπ;−π;0 and \(\bar K\) 0nπ;−π;+ have been studied in a bubble-chamber experiment with a beam of 6 GeV/c kaons. Cross-sections are given for the various resonances produced in each channel. The low mass enhancement in the Kπ;π; system is discussed. There is a significant difference in the production of the K*−(890) in the channels K*−nπ;+ and K*−pπ;0. No evidence of the L-meson, seen in other K+ and K− experiments, is found and an upper limit is set on its production.
Riassunto
Si sono studiate le reazioni K−p→K−pπ;−π;+, \(\bar K\) 0pπ;−π;0 e \(\bar K\) 0nπ;−π;+ in esperimenti in camera a bolle con un fascio di kaoni di 6 GeV/c. Si forniscono le sezioni d’urto per le varie risonanze prodotte in ogni canale. Si discute il piccolo aumento di massa nel sistema Kπ;π;. Vi è una differenza significativa nella produzione di K*−(890) nei canali K*−nπ;+ e K*−pπ;0. Non vi è alcuna prova dell’esistenza del mesone L, visto in altri esperimenti con K+ e K−, e si pone un limite superiore alla sua produzione.
Реэуме
Были исследованы реакции K−p→K−pπ;−π;+, \(\bar K\) 0pπ;−π;0 и \(\bar K\) 0nπ;−π;+ в Экспериментах в пуэырьковой камере с пучком каонов с импульсом 6 ГЭB/c. Приводятся поперечные сечения для раэличных реэонансов, рожденных в каждом канале. Обсуждается увеличение при малой массе в системе Kπ;π;. Сушествует эначительное раэличие в рождении K*-(890) в каналах K*−nπ;+ и K*−pπ;0. Не обнаружено подтверждений L-меэона, наблюденного в других K+ и K− Экспериментах, и устанавливается верхний предел для рождения L-меэона.
