Abstract

In this research plan is proposed to carry out the study of phenomenological processes of High Energy Physics, specifically radiative corrections in extensions of the Standard Model of various processes at one-loop level, in order to explore and analyze the possibility of detecting deviation of the Standard Model due to the effects of new physics near to the scale of TeVs energy. The proposed phenomenological processes are rare decays of a new neutral gauge boson Z', predicted in many extensions of the Standard Model, into known particles such as Z' -> ggZ, ggH, \gama\gama Z, \gama ZZ, \gama\gama H, HZZ; and also the gluon fusions gg -> \gama\gama, \gama Z, HH, H\gama, HZ, ZZ with intermediate Higgs and box contributions from quantum fluctuations caused by new exotic virtual particles arising from the extensions. In particular is of great interest to perform such processes in the model 3-3-1, based on the gauge group SUC (3) x SUL (3) × UX (1). (AU)
