The dispersion relation of energetic (few TeV) neutrinos traversing a medium is studied. We use the real time formalism of thermal field theory and we include the effects from the propagator of the W gauge boson. We consider then the MSW oscillations for cosmic neutrinos traversing the Earth, adopting for the neutrino parameters values suggested by the LSND results. It is found that the νμ flux...

The explosion of the World Wide Web as a global information network brings with it a number of related challenges for information retrieval and automation. The link structure, which is the main feature of the hypermedia environment, can be a rich source of information for exploration. This paper is centered around the exploiting of hyperlinks in the subject of automatic discovery. In this paper...
