The modified forms of propagators and runningcoupling constant are obtained by non-perturbative methods. The processes investigated includes the diffractiveones proton-proton elastic scattering, light vector meson photo-production and double vector meson productionin gamma-gamma scattering as well as the pion and kaon meson form factors. The results are comparedwith experimental data (if available), showing a good agreement with a gluon with dynamical mass but do notindicate the correct gluon propagator functional form. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437441 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.2B Vol.37 |
