Sensitivities to neutrino oscillation parameters for possible very long baseline neutrino oscillation experiments are discussed. The reach for observing a non-zero mixing angle θ13, establishing CP violation and determining the mass hierarchy are compared between various experimental options. Different possibilities for neutrino beams are briefly described, as well as the assumptions about the ...

The Super-Kamiokande experiment, using the world's largest underground water Cherenkov detector, has been running since April 1, 1996. The total live time for the analysis has reached more than 350 days. The latest results on atmospheric neutrinos, solar neutrinos, and related topics are reported. c 1997 by Yoshitaka Itow.

Abstract In the framework of development SWGO experiment, we have performed a detailed study single unit an extensive air shower observatory based on array water Cherenkov detectors. Indeed, one possible detector configurations for consists tanks, and to reach high detection efficiency discrimination capability between gamma-ray hadronic showers, different tank designs are under investigation. ...

We review the recent developments in the field of ultrafast Cherenkov fiber lasers. Two essential properties of such laser systems - broad wavelength tunability and high efficiency of Cherenkov radiation wavelength conversion are discussed. The exceptional performance of the Cherenkov fiber laser systems are highlighted - dependent on the realization scheme, the Cherenkov lasers can generate th...

The discovery of the neutrino oscillations in 1998 revisited the interest of proton decay search [2]. The existence of the tiny neutrino mass indicates the existence of the large energy scale behind and suggests the connection between the small neutrino mass and proton decay. There are strong indications of the unification scale of O(10 16)GeV: the running coupling constants with super-symmetri...
