Hadronlike part of the photon structure functions

Адронно-подобная часть структурных функций фотона

Il Nuovo Cimento A (1965-1970)

Summary

The hadronlike part of the photon structure function is related to the cross-section of e+e− annihilation into hadrons. The timelike photon is described as a meson, with quark and gluon contents. We calculate explicitly its structure functions and establish an integral relation between the spacelike structure functions and the timelike ones. A numerical application is done.

Riassunto

La parte di tipo adronico della funzione di struttura del fotone è collegata alla sezione d'urto dell'annichilazione e+e− in adroni. Il fotone di tipo tempo è descritto come un mesone con contenuto di quark e gluoni. Si calcolano esplicitamente le sue funzioni di struttura e si stabilisce una relazione integrale tra le funzioni di struttura di tipo spazio e quelle di tipo tempo. Si effettua un'applicazione numerica.

Резюме

Адронно-подобная часть структурных функций фотона связывается с поперечным сечением e+e− аннигиляции в адроны. Времениподобный фотон описывается как мезон, содержащий кварки и глуоны. Мы вычисляем в явном виде структурные функции фотона и устанавливаем интегральное соотношение между пространственно-подобными структурными функциями и времени-подобными структурными функциями. Приводятся численные примеры.
