论文摘要
tritium beta-decay是以模型无关的方式测量活性光中微子绝对质量的最有希望的方法。在未来的实验中,回旋辐射发射光谱技术的发展和使用原子trimic的使用有可能通过数量级来改善当前限制。在本文中,我们分析了这种未来搜索对kev-mas无菌中微子的潜在敏感性以及活性或无菌中微子的外来相互作用。我们计算出发射电子的能量和角度相关的衰减分布,相对于tri的潜在极化,包括干扰标准模型情况,以及对原子tri骨的相关最终状态校正。我们提出了对活性 - 菌群中微子混合和外来电流有效耦合常数的敏感性,这表明在tri虫实验中探测新物理的潜力。
Tritium beta-decay is the most promising approach to measure the absolute masses of active light neutrinos in the laboratory and in a model-independent fashion. The development of Cyclotron Radiation Emission Spectroscopy techniques and the use of atomic tritium has the potential to improve the current limits by an order of magnitude in future experiments. In this paper, we analyse the potential sensitivity of such future searches to keV-mass sterile neutrinos and exotic interactions of either the active or sterile neutrinos. We calculate the relevant decay distributions in both energy and angle of the emitted electron with respect to a potential polarisation of the tritium, including the interference with the Standard Model case as well as incorporating relevant final state corrections for atomic tritium. We present projected sensitivities on the active-sterile neutrino mixing and effective coupling constants of exotic currents, demonstrating the potential to probe New Physics in tritium experiments.
