Toward exploring unknowns in the lepton flavor mixing

Abstract:

In this talk I focus in on some of the relatively unexplored aspects of neutrino masses and lepton flavor mixing. They are (1) possible deviation of Θ23 from the maximal, and (2) serious consequences of our ignorance of the sign of Δm132 on the interpretation of future CP violation measurement. I emphasize that the accuracy of s232 determination that already achieved by the Super-Kamiokande atmospheric neutrino observation will not be improved significantly by the next-generation LBL experiments for nearly maximal Θ23. I also stress that, unless we know the sign of Δm132, detection of CP violation in the JPARC-SK experiment would suffer from the problem of confusion to CP conservation. Clearly, better strategies which so far escaped our attention are called for to determine these quantities. © 2004 Elsevier B.V. All rights reserved.
