  • Atmospheric neutrinos with three flavor mixing 
    Narayan M.; Rajasekaran G.; Sankar S.U. (1997)
    We analyze the atmospheric neutrino data in the context of three flavor neutrino oscillations taking account of the matter effects in the Earth. With the hierarchy among the vacuum mass eigenvalues [Formula presented], the ...
  • Solar and atmospheric neutrino oscillations with three flavors 
    Narayan M.; Murthy M.V.N.; Rajasekaran G.; Umasankar S. (1996)
    We analyze the solar and the atmospheric neutrino problems in the context of three flavor neutrino oscillations. We assume a mass hierarchy in the vacuum mass eigenvalues (formula presented), but make no approximation ...
  • Solar eclipse and neutrinos 
    Narayan M.; Rajasekaran G.; Sinha R. (1996)
    It is pointed out that due to neutrino oscillations the observed solar neutrino rate in the terrestrial neutrino detectors may be enhanced during a partial or total solar eclipse. The enhancement is calculated as a function ...
  • Solar neutrinos and the eclipse effect 
    Narayan M.; Rajasekaran G.; Sinha R.; Burgess C.P. (1999)
    The solar neutrino counting rate in a real time detector such as Super-Kamiokanda, SNO, or Borexino is enhanced due to neutrino oscillations in the Moon during a partial or total solar eclipse. The enhancement is calculated ...
  • Three flavor implications of the result of the CHOOZ Collaboration 
    Narayan M.; Rajasekaran G.; Sankar S.U. (American Institute of Physics Inc., 1998)
    We analyze the recent result of the CHOOZ Collaboration in the context of mixing and oscillations between all the three neutrino flavors. If one assumes the hierarchy among the vacuum mass eigenvalues δ21≪δ31 where δ21=μ22-μ21 ...
  • Time-of-night variation of solar neutrinos 
    Narayan M.; Rajasekaran G.; Sinha R. (World Scientific Publishing Co. Pte Ltd, 1998)
    We investigate the time-of-night variation of solar neutrino rate which will be of relevance to super-Kamioka and Sudbury neutrino detectors in the framework of oscillations among the three flavors. An analytical method ...
