Summary
The proton structure functions from electron and muon scattering are investigated with recourse to the operator product expansion. The hadrons are assumed to be the composite particles of the four-colour triplet quarks interacting through the non-Abelian gauge gluons. The quark-quark and gluon-gluon scatterings are examined by comparing with experimental data. It is shown that the experimental data can be realized by using the same Regge parameters for the constituent-particle scattering as in high-energy hadron processes.
Riassunto
Si studiano le funzioni di struttura del protone dallo scattering dell'elettrone e del muone ricorrendo allo sviluppo del prodotto degli operatori. Si suppone che gli adroni siano le particelle composte dei quark del tripletto a 4 colori che interagiscono tramite i gluoni del gauge non abeliano. Si esaminano gli scattering quark-quark e gluonegluone confrontando con i dati sperimentali. Si mostra che i dati sperimentali possono essere realizzati usando gli stessi parametri di Regge per lo scattering della particella costituente come nei processi adronici ad alta energia.
