    “…Under the assumption that the density variation of the electrons can beapproximated by an exponential function, the solar Mikheyev-Smirnov-Wolfensteineffect is treated for three generations of neutrinos. The generalizedhypergeometric functions that result from the exact solution of this problemare studied in detail, and a method for their numerical evaluation ispresented. …”

    “…We study the sensitivity of the HELLAZ and Borexino solar neutrino experiments on discriminating the neutrino species nu_e, anti-nu_e, nu_{mu,tau}, anti-nu_{mu,tau}, and nu_{sterile} using the difference in the recoil electron kinetic energy spectra in elastic neutrino-electron scattering. …”

    Publicado 2000
    “…After briefly reviewing how such dimensions can lower the fundamental GUT, Planck, and string scales, I then outline how these scenarios lead to a new higher-dimensional seesaw mechanism for generating neutrino oscillations --- perhaps even without neutrino masses. …”

    “…A detailed description of a Tret'yakov-type magnetic$\beta$--spectrometer with electrostatic acceleration is presented.The instrument is being used for high precision measurements of the$ \beta $--spectra of various isotopes and to search for neutrinomixing and heavy neutrinos with masses up to $100 \,$keV$/c^2$.The relative momentum resolution, obtained with an extendedsource ($ 3 \times 2 \,$cm$^2$) and a large silicon stripdetector, is $ \delta p/p = 6.9 \times 10^{-4} $ (FWHM).The width of the energy band, which can simultaneously be measuredwith this resolution, is typically 50 times larger than thecorresponding width of the energy resolution.The detector delivers pulse-height and one-dimensional positioninformation. …”
