Summary
\(\bar p\Lambda ^0 K^ + \),\(\bar p\Lambda ^0 K^0 \pi ^ + \) and\(\bar p\Lambda ^0 K^ + \pi ^0 \) strange-particle final states, produced in\(\bar pp\) collisions at 5.7 GeV/c, were studied in the CERN 2 metre HBC. Cross-sections for the various channels are presented. It was found that about half of the channel cross-sections are accounted for by resonance production. Several features of the resonance production are discussed. The results are compared with those obtained in pp interactions at a similar energy.
Riassunto
Avvalendosi della HBC di 2 metri del CERN si sono studiati gli stati finali delle particelle dotate di stranezze\(\bar p\Lambda ^0 K^ + \),\(\bar p\Lambda ^0 K^0 \pi ^ + \) e\(\bar p\Lambda ^0 K^ + \pi ^0 \), prodotti negli urti\(\bar pp\) a 5.7 GeV/c. Si danno le sezioni d’urto relative ai vari canali. Si è trovato che circa la metà delle sezioni d’urto dei canali sono spiegate dalla produzione di risonanze. Si discutono numerosi aspetti della produzione di risonanze. Si confrontano i risultati con quelli ottenuti nelle interazioni pp ad energie simili.
Реэюме
В ЦЕРНе на 2 м водородной пуэырьковой камере исследовались конечные состояния со странными частицами\(\bar p\Lambda ^0 K^ + \),\(\bar p\Lambda ^0 K^0 \pi ^ + \) и\(\bar p\Lambda ^0 K^ + \pi ^0 \), которые рождались при\(\bar pp\) соударениях с импульсом 5.7 ГзВ/с. Приводятся поперечные сечения для раэличных каналов. Обнаружено, что около половины поперечных сечений общясняются реэонансным рождением. Обсуждаются некоторые особенности реэонансного рождения. Полученные реэультаты сравниваются с реэультатами рр вэаимодействий при той же знергии.
