The aim of the project is to shed light on the theoretical origin of neutrino masses and to explore their consequences in particle physics, astroparticle physics and cosmology. The precision era in neutrino physics is expected to put the proposed theoretical models to test. We will lay emphasis on the seesaw mechanism to explain small neutrino masses. The model predictions for neutrino oscillations, LHC, lepton flavor violation and leptogenesis will be studied. Concrete flavor models taking into account new data will be constructed explicitly and dark matter candidates will be identified. Renormalization group effects to relate new physics at high scale with observations at low energies will be studied. More exotic physics such as presence of light sterile neutrinos, non-standard interactions, unitarity violation, will be probed. The prospects of using neutrino telescopes to probe both neutrino properties as well as astrophysical sources will be studied.

该项目的目的是阐明中微子质量的理论起源，并探索它们在粒子物理学、天体粒子物理学和宇宙学中的后果。中微子物理学的精确时代有望对提出的理论模型进行测试。我们将着重于跷跷板机制来解释小质量的中微子。将研究中微子振荡、LHC、轻子味破坏和轻子生成的模型预测。考虑到新数据的具体风味模型将被明确构建，暗物质候选者将被确定。将研究重整化群效应，以将高尺度的新物理与低能量的观测联系起来。更多的奇异物理，如光无菌中微子的存在，非标准相互作用，幺正性破坏，将被探测。将研究利用中微子望远镜探测中微子性质和天体物理来源的前景。
