A study of the reaction K−p→K−ϕp at 8.25 GeV/c

Исследование раекции K−p→K−ϕp при 8.25 ГэB/c

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The dissociation of a K− into the K−ϕ system is studied at 8.25 GeV/c. The cross-section for K−ϕp production is (27±2) μb. All the expected properties of diffraction are found (mass spectrum, mass-slope correlation, 1+ S wave dominance). There is also an indication of the Kϕ decay mode of a 2− resonance in theL region.

Riassunto

Si studia la dissociazione di un K− nel sistema K−ϕ a 8.25 GeV/c. La sezione d'urto per la produzione di K−ϕp è (27±2) μb. Si trovano tutte le proprietà attese della diffrazione (spettro di massa, correlazione massa-pendenza, dominanza dell'onda 1+ S). C'è anche indicazione del modo di decadimento Kϕ di una risonanza 2− nella regioneL.

Резюме

Исследуется диссоциация K− на систему K−ϕ при 8.25 ГэB/c. Поперечное сечение образования K−фp составляет (27±2) мб. Обнаруживаются все ожидаемые свойства дифракции (массовый спектр, корреляция массового наклона, доминантность 1+ S волны). Также обнаружена мода Kϕ распада для 2− резонанса вL области.
