Summary

The UA1 group has reported a large\(\bar BB\) production cross-section at\(S\bar ppS\) energies (∼1μb). Following this observation we indicate how the large rate of B mesons produced in\(\bar pp\) collisions could be used to search for and detect various rare decays. We consider several specific decays and the theoretical expectations and implications of the detections of these decays. Tests of the GIM model, horizontal symmetry andCP violation can be carried out in this manner. A spectrometer consisting of a CCD telescope, a magnetized muon detection spectrometer and an e.m. shower detector is described.

Riassunto

Il gruppo UA1 ha pubblicato un valore numerico elevato della sezione d'urto di produzione\(\bar BB\) alle energie del\(S\bar ppS\) (∼1μb). In seguito a quest'osservazione, noi indichiamo come la grande quantità di mesoni B prodotti nelle collisioni\(\bar pp\) potrebbe essere usata per la ricerca e la rivelazione di diversi decadimenti rari. Noi consideriamo vari decadimenti specifici, le loro previsioni teoriche e le implicazioni della rivelazione di questi decadimenti. In questa maniera si potrebbero effettuare dei test sul modello GIM, sulla simmetria orizzontale e sulle violazioni diCP. Si descrive uno spettrometro che consiste di un telescopio a CCD, di uno spettrometro magnetizzato per la rivelazione dei muoni, e di un rivelatore di sciami elettromagnetici.

Резюме

Группа UA1 сообщила о болыпом поперечном сечении рождения\(\bar BB\) при\(S\bar ppS\) знергиях (∼1 мкб). Следуя зтому наблюдению, мы покзыаем, как болыпая интенсивность В мезонов, образованных в\(\bar pp\) соудареняях, может быть использована для поиска и детктирования различных редких распадов. Мы рассматриваем некоторые специальные распады, теоретические предсказания и приложения результатов детектирования зтих распадов. Проводится проверка GIM модели, горизонтальной симметрии иCP нарушения. Опсиывается спектрометр, который состоит из CCD телескопа, магнитного мюонного спектрометра и детектора e.m. ливней.
