Directional coherence of medium-energy protons emitted in12C-Em interaction at 4.5 GeV/c/n

Summary

In this paper we present an interesting experimental observation in central12C-AgBr interaction at 4.5 GeV/c per nucleon,viz. the observation of directional coherence of the target protons (Z=1) revealing a probable « back to back » effect due to the formation of a multinucleon fireball in the target nucleus, which might probably indicate the formation of a quark gluon cluster.

Riassunto

In questo lavoro presentiamo un’interessante osservazione sperimentale sull’interazione centrale12C-AgBr a 4.5 GeV/c per nucleone, ossia l’osservazione riguardo alla coerenza direzionale dei protoni del bersaglio (Z=1) che rivela un probabile effetto « back to back » dovuto alla formazione di una sfera di fuoco multinucleonica nel nucleo del bersaglio, il che probabilmente indica la formazione di un cluster gluonico di quark.

Реэюме

В зтой статье мы предлагаем интересное зкспериментальное наблю-дение центрального12C-AgBr вэаимодействия при 4.5 ГзВ/с на нуклон, а именно, наблюдение направленной когерентности для протонов мищени (Z=1), которая обнаруживает вероятный зффект, обусловленный обраэованием многонуклонного файрбола в ядре мищени, который вероятно укаэывает на обраэование кварк-глюонного кластера.
