Weak and electromagnetic interactions in the quarkbarton model

This thesis deals with the naive quark parton model as means of explaining deep inelastic scattering phenomena. The formalism of the quark model is reviewed as is the parton model and its main results. The Kuti-Weisskopf quark parton model is introduced and used to make predictions for charged and neutral current neutrino experiments. An attempt is made to improve the Kuti-Weisskopf model predictions and we propose a model in which new hadronic constituents, besides the p,n,λ and charmed p' quarks participate. In this model the new particles are classified in SU(2) triplets of the Weinberg model. Wu an.ilyee charged and neutral current neutrino experiments and construct a model which is a modification of a quark model proposed by R.Mc. Elhaney and S.F. Tuan. In the light of recent work on nonleptonic interactions of the electron we consider both electron positron annihilation and deepinelastic scattering. Finally, we propose a scheme in which "naive quark parton model' techniques can give (logs)(^2) behaviour for the hadronic total cross sections.
