标题： A new three flavor oscillation solution of the solar neutrino deficit in R-parity violating supersymmetry

摘要： 我们提出了一种利用三种中微子味在R宇称破缺超对称模型中解决太阳中微子亏缺问题的方案。在真空中，质量和混合限制在仅涉及ν(μ)-ν(τ)扇区，我们选择该限制以与大气中微子异常的要求相一致。ν(e)是无质量且未混合的。模型中存在的味改变和味对角中性流以及太阳中的能量依赖共振诱导的ν(e)-ν(μ)混合导致了新的太阳中微子问题解决方案。对太阳中微子速率和光谱（1258天SK数据）的最佳拟合要求两个最轻中微子在真空中具有10^{-5}eV^2的质量平方差。此解无法容纳显著的日-夜效应。 显示英文摘要

摘要： We present a solution of the solar neutrino deficit using three flavors of neutrinos within the R-parity non-conserving supersymmetric model. In vacuum, mass and mixing is restricted to the nu(mu)-nu(tau) sector only, which we choose in consistency with the requirements of the atmospheric neutrino anomaly. The nu(e) is massless and unmixed. The flavor changing and flavor diagonal neutral currents present in the model and an energy-dependent resonance-induced nu(e)-nu(mu) mixing in the sun result in the new solution to the solar neutrino problem. The best fit to the solar neutrino rates and spectrum (1258-day SK data) requires a mass square difference of 10^{-5} eV^2 in vacuum between the two lightest neutrinos. This solution cannot accommodate a significant day-night effect for solar neutrinos.
