CAMPOS, S. D.; MENON, M. J. and MONTANHA, J.. On the slope of the elastic differential cross sections. Braz. J. Phys. [online]. 2007, vol.37, n.1a, pp.80-83. ISSN 1678-4448. http://dx.doi.org/10.1590/S0103-97332007000100024.
Making use of a model-independent analytical fit for the elastic hadron-hadron amplitude, recently developed, we investigate the slope of the proton-proton and antiproton-proton differential cross sections, as a function of the energy and the momentum transfer. We show that the predictions for these quantities are in agreement with the experimental data available and discuss the effect of the slope position as function of the momentum transfer.
