Vacuum and MSW interpretations of solar neutrino data with the LNW mass matrix

The Lehmann-Newton-Wu mass matrix, which was recently applied to neutrinos, is further investigated. The analytic results presented earlier are confirmed numerically for the solar density profile of the Standard Solar Model. The combined analysis of atmospheric and solar neutrino data favors the MSW solution over the vacuum-oscillation solution. The total rates from the solar neutrino detectors and spectrum distortion reported by the Super-Kamiokande collaboration for solar neutrinos favors one heavy (m3\sim 0.05 eV) and two light (m1, m2\lsim 0.003 eV) neutrinos.Comment: 14 pages, LaTeX, including figures. v3: Polishing, reference adde

Positron Polarization at the International Linear Collider

We review some recent arguments supporting the upgrade of the International Linear Collider by a polarized positron beam, in addition to the polarized electron beam. The examples presented here mainly focus on the impact of positron polarization on items relevant to new physics searches, such as the identification of novel interactions in fermion-pair production and the formulation of new CP-sensitive observables. In particular, in addition to the benefits from positron and electron longitudinal polarizations, the advantages in this field of having transverse polarization of both beams are emphasized.Comment: Invited talk at 2005 International Linear Collider Workshop, Stanford Ca (LCWS05) 6 pages, LaTeX, 2 eps figure
