Resumen
In my thesis I investigate the relevance of radiative corrections in two different extensions of the Standard Model of Particle Physics. In the first topic I investigate, within the Minimal Supersymmetric Standard Model,the chargino pair production at a future International Linear Collider (ILC) at next-toleading order in the electroweak sector of the theory. A dipole substraction formalism is implemented in order to enhance the precision in the electromagnetic sector. Also thehelicity states of the chargino as well as the polarization of the incorning electron and positron are considered. The conclusion here was that the perturbative effect must be included in the theoretical calculation of the chargino pair cross section as well as theirmasses, because the corrections are larger than the precision of the experiment. In the second topic, I study the signal h--+ 11 in a non-supersymmetric Two-Higgs Doublet Model, where a neutral Higgs boson has very suppressed couplings to ferrnions(fermiophobic Higgs boson). Here, the charged Higgs loop effect is included, showing that the correction corning from the theory is comparable with the expected sensitivities in the measurement of the Branching ratio h --+ 11 in the next generation of accelerators, LHC and ILC.
