À Procura de Algumas Evidências de Física Além do Modelo Padrão
Keywords in Portuguese
fenomenologia
Física de colisores
leptoquarks
Abstract in Portuguese
Apresentamos um estudo fenomenológico de algumas extensões do modelo padrão da física de partículas no LEP e no LHC. Concentramos nossa atenção, em particular1 na busca por evidências de supersimetria com violação de paridade--R no LEP I, LEP II e LHC. Estudamos um modelo supersirnétrico com violação espontânea de paridade-R bem como um modelo efetivo onde a violação ocorre explicitamente. Realizamos, também, um estudo independente de modelo para leptoquarks no LHC a partir de colisões eq baseado em uma lagrangiana efetiva. Mostramos que os efeitos destas duas extensões do modelo padrão poderão ser visíveis no intervalo de energia dos aceleradores considerados.

Abstract in English
We present a phenomenologic study of some extensions of standard model of elementary particles at LEP and LHC. We concentrate our attention, for instance, on the search of R-parity violating supersymmetry evidences at LEP I, LEP II and LHC. We study a spontaneous R-parity violating model as well an effective one where the violation occurs explicitly. We also perform an independent model study on leptoquarks at LHC coming from e q collisions, in the frame of an effective lagrangian. We show that the effects of these two standard model extensions can be visible in the range of energy of the chosen colliders.
