Menon Física, Astronomía y Matemáticas Making use of the extrema bounds for the soft pomeron intercept, recently determined by fits to pp and ¹pp data(from both accelerator and cosmic-ray experiments), we investigate the total cross sections for pion-proton,kaon-proton, gamma-proton and gamma-gamma scattering. We show that by means of global fits, the extremabounds are in agreement with the bulk of experimental data presently available, and that extrapolations to higherenergies indicate different behaviors for the rise of the total cross sections. We also discuss factorization andquark counting, showing that both bounds are in agreement with these properties. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46400124 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.34 |
