Research in theoretical elementary particle physics will be concerned with the electromagnetic and gravitational properties and interactions of neutrinos, when they propagate through a dense medium such as the Sun, a supernova, or through the environment of dense objects such as active galactic nuclei. Detailed calculations of the transition rates for various processes involving neutrinos propagating under such conditions will be performed. These results are needed in order to understand the physics of neutrinos in such environments, which is important for testing the consequences of the recent experimental observations that indicate that neutrinos have a small, non-zero value of the mass.

理论基本粒子物理学的研究将关注中微子的电磁和引力特性以及相互作用，当它们通过致密介质（如太阳，超新星）或通过致密物体（如活动星系核）的环境时。 将详细计算在这种条件下中微子传播的各种过程的跃迁率。 需要这些结果来理解中微子在这种环境中的物理学，这对于测试最近的实验观测结果非常重要，这些实验观测表明中微子具有较小的非零质量值。
