用马尔可夫链蒙特卡罗方法估计中微子参数
Global neutrino parameter estimation using Markov Chain Monte Carlo
摘要:
我们提出了一个马尔可夫链蒙特卡罗全球分析中微子参数使用宇宙学和实验数据。结果的组合,目前所有可用的数据从振荡实验,宇宙学,和中微子双β衰变。此外,我们明确研究宇宙学,氚衰变和中微子双β衰变数据之间的相互作用,在确定中微子质量参数。我们还讨论了如何推断非中微子宇宙学参数可以受益于未来的中微子质量实验,如KATRIN氚衰变实验或无中微子双β衰变实验。
英文摘要:
We present a Markov Chain Monte Carlo global analysis of neutrino parameters using both cosmological and experimental data. Results are presented for the combination of all presently available data from oscillation experiments, cosmology, and neutrinoless double beta decay. In addition we explicitly study the interplay between cosmological, tritium decay and neutrinoless double beta decay data in determining the neutrino mass parameters. We furthermore discuss how the inference of non-neutrino cosmological parameters can benefit from future neutrino mass experiments such as the KATRIN tritium decay experiment or neutrinoless double beta decay experiments.
