Diffractive Electroproduction of ρ Mesons

Full Text PDF

Abstract:

A tow pomeron model is used to analyze the distribution of the p mesons electroproduction cross section with energy for different Q². It is found that the steepness in the energy distribution can be attributed to the increase of the respective weight of the hard pomeron to the soft pomeron with increasing Q². Using some suitable functions to fit the variations of the weights with Q², a remark able agreement with the experimental data is achieved
