Abstract

Correlations between pions produced in pp collisions at 69 GeV/c are observed both for π−π+ and π−π− Shortrange correlations in rapidity are present fory1⋍y2 in both cases an enhancement is seen aroundy1=y2=±1 Correlations between transverse variables are linked to those in rapidity for π−π− combinations whereas the effect is essentially kinematical for π+π−Исследуются корреляции между пионами π−π+ и π−π− рожденными в рр соударениях при 69 ГзВ/с Отмечаются короткодействуюшие корреляции дляy1⋍y2 воэрастание обнаруживается вблиэиy1=y2=±1 Корреляции между поперечными переменными свяэаны с корреляциями для π−π− комбинаций тогда как для π+π− укаэанный зффект является по сушеству кинематическимSi osservano correlazioni fra pioni prodotti nelle collisioni pp a 69 GeV/c sia per π−π+ che per π−π− Correlazioni di breve raggio in rapidità sono presenti pery1⋍y2 in entrambi i casi si nota un aumento attorno ay1=y2=± 1 Le correlazioni fra le variabili trasversali sono collegate a quelle in rapidità per le combinazioni di π−π− mentre l’effetto è essenzialmente cinematico per π+π−
