Summary
The constituent approach to strong and electromagnetic hadron interactions requires weak coupling at large momentum transfer, to obtain scaling, and strong coupling at low momentum transfer, to permit quark confinement. Asymptotically free or weakly coupled hard interactions do not provide multiparticle production. Thus soft high-energy quark-quark interactions constitute a universal jet mechanism for multihadron production in soft and in hard hadron-hadron collisions, as well as in deep inelastic lepton-hadron scattering and in e+e− annihilation.
Riassunto
L'approccio costituente ad interazioni adroniche forti ed elettromagnetiche richiede un accoppiamento debole a grandi impulsi trasferiti per ottenere la variazione di scala, e un accoppiamento forte a bassi impulsi trasferitii per permettere il confinamento dei quark. Le interazioni dure asintoticamente libere o accoppiate debol mente non forniscono la produzione di molte particelle. Perciò le interazioni molli quark-quark ad alta energia del costituiscono un meccanismo a getto universale sia per la produzione di molti adronica in collisioni adrone-adrone molli e dure che per lo scattering profondo anelastico leptone-adrone e per l'annichilazione e+e−.
Резуме
Составной подход к сильным и электромагнитным взаимодействиям адронов требует слабой связи при больших передаваемых импульсах для получения скейлинга и сильной связи при малых передаваемых импульсах, чтобы допустить удержание кварков. Асимптотически свободные или слабо связанные взаимодействия не обеспечиваут многочастичного рождения. Следовательно, «мягкие» кварккварковые взаимодействия при высоких энергиях основывают универсальный «струйный» механизм для многоадронного рождения при «мягких» и «жестких» соударениях адрона с адроном, а также при глубоко неупругом лептон-адронном рассеянии и e+e− аннигиляции.
