AbstractAbstract
[en] In this work, we demonstrate that the silicon detectors can be also used in the identification mode, by pions, kaons and protons discrimination, in the region lower than 1 GeV/c2. This work has been motivated by the aspect complementary to the particle identification by the energy loss in the Tpc of Delphi. On the other hand, in the new detector designed for the experimental front region consisting of only silicon detectors, this mode offers a unique opportunity for particle identification

AbstractAbstract
[en] We review the status of ultrahigh energy cosmic rays studies, discussing the mechanisms for their production and propagation through space. We look into the strategy to measure those events and describe a new observatory, which is in construction, to observe those particles, the Pierre Auger Observatory. (author)

AbstractAbstract
[en] The neutrinos are excellent witness of astrophysics processes at ultra high energies. Neutrinos with energies greater than GZK cut-off do not lose their energies travelling then cosmological distances and without deflection. These neutrinos can give us new information. We investigate in the literature about the passable sources of ultra high energy neutrinos and the cross sections with nucleons at this energies. There are some problems in the detection of the neutrinos because of the low cross sections and the low flux at this energies. The Pierre Auger Project would be planned to have the possibility of this detection. (author)

AbstractAbstract
[en] The oscillation between the B0d - B-bar0d mesons is one of two examples of particle-antiparticle oscillation, a quantum phenomenon with macroscopic consequences, and the other being the K0 - K-bar0. This phenomenon has been first observed in the B system in 1987, by the ARGUS experiments, at DESY and U A1, CERN. Such phenomenon can be originated in quantum character of the physical states associated to the B0 s
