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，天线物理学和宇宙学中的后果。预计中微子物理学的精确时代将使所提出的理论模型进行测试。我们将重点放在Seesaw机制上，以解释小型中微子肿块。将研究中微子振荡，LHC，Lepton侵犯和瘦素发生的模型预测。考虑到新数据的混凝土风味模型将明确构建，并将确定候选暗物质。将研究重新归一化组的效应，以将新的物理学与低能量的观测相关联。将探测更多异国情调的物理学，例如光无菌中微子的存在，非标准相互作用，违反单位性的相互作用。将研究使用中微子望远镜探测中微子性质以及天体物理来源的前景。
