1. On new gauge boson signals according to the littlest higgs model in future e+ e- colliders
There is a recent proposal of identifying the Higgs particle of the Standard Model as a pseudo Nambu-Goldstone boson. This new broken symmetry introduces new particles and new interactions. Among these new interactions a central role to get an experimental signal of a new physics is played by the new neutral gauge bosons, A H and Z H. We study the associated

2. Asymmetries in the littlest Higgs model
Little Higgs models were recently proposed as an alternative for models of electroweak symmetry breaking. They can be regarded as one of the important candidates of the new physics beyond the Standard Model. We consider here the phenomenology of the minimal model of this type, the "Littlest Higgs Model" (LHM). It predicts the existence of the new gauge boson

3. Generalized z-scaling and pp collisions at RHIC
New generalization of the z-scaling in inclusive particle production is proposed. The scaling variable z is expressed in terms of the momentum fractions x1 and x2 of the incoming protons. Explicit dependence of z on the momentum fractions y a and y b of the scattered and recoil constituents carried by the inclusive particle and recoil object is included. The

4. À Procura de Algumas Evidências de Física Além do Modelo Padrão / Looking for Some Evidence of Physics Beyond the Standard Model
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
