We propose that the solar neutrino deficit may be due to oscillations of mass-varying neutrinos (MaVaNs). This scenario elucidates solar neutrino data beautifully while remaining comfortably compatible with atmospheric neutrino and K2K data and with reactor antineutrino data at short and long baselines (from CHOOZ and KamLAND). We find that the survival probability of solar MaVaNs is independent of how the suppression of neutrino mass caused by the acceleron-matter couplings varies with density. Measurements of MeV and lower energy solar neutrinos will provide a rigorous test of the idea.
我们提出，太阳中微子亏损可能是由于质量可变中微子（MaVaNs）的振荡所致。这种情况能很好地解释太阳中微子数据，同时与大气中微子和K2K数据以及短基线和长基线（来自CHOOZ和KamLAND）的反应堆反中微子数据保持良好的兼容性。我们发现，太阳MaVaNs的生存概率与由加速子-物质耦合引起的中微子质量抑制如何随密度变化无关。对MeV及更低能量太阳中微子的测量将对这一观点进行严格检验。
