Particle physics and cosmology of neutrinos

中微子是一类特别有趣的基本粒子。粒子物理的标准模型认为中微子的质量恰好为零。然而，最近的实验数据几乎证明了无质量中微子与观测结果不一致。如果中微子有质量，那么当它们在太空中传播时，量子力学允许它们在不同类型的中微子之间振荡。非零中微子质量和相关的振荡导致了基本粒子领域和宇宙学中重要的新物理学。这个项目将探索中微子振荡在粒子物理和宇宙学不同领域的影响。

Neutrinos are a particularly interesting class of elementary particle. The Standard Model of particle physics sees neutrinos as having exactly zero mass. However, recent experimental data have all but demonstrated that massless neutrinos are inconsistent with observations. If neutrinos have mass, then quantum mechanics allows them to oscillate between the different neutrino types as they propagate through space. Nonzero neutrino masses and the associated oscillations lead to important new physics in the elementary particle domain and in cosmology. This project will explore the implications of neutrino oscillations in diverse areas in particle physics and cosmology.
