Exploring the Potential of Short-Baseline Physics at Fermilab

O. G. Miranda, Pedro Pasquini, M. Tórtola, J. W. F. Valle

摘要:

我们研究了费米实验室的短基线中微子计划探测轻子混合矩阵的么正性的能力。我们发现灵敏度比目前的稍好。受未来DUNE实验的启发,我们还分析了LBNF光束线中额外的液态氩近探测器的潜力。将这样的近检测器添加到DUNE设置将大大提高电流对非么正性的灵敏度。这将有助于消除由于中微子混合矩阵中存在新的复杂相而导致的CP简并。我们还研究了我们提出的设置的灵敏度,以轻不育中微子的各种配置。

英文摘要:

We study the capabilities of the short baseline neutrino program at Fermilab to probe the unitarity of the lepton mixing matrix. We find the sensitivity to be slightly better than the current one. Motivated by the future DUNE experiment, we have also analyzed the potential of an extra liquid Argon near detector in the LBNF beamline. Adding such a near detector to the DUNE setup will substantially improve the current sensitivity on non-unitarity. This would help to remove CP degeneracies due to the new complex phase present in the neutrino mixing matrix. We also study the sensitivity of our proposed setup to light sterile neutrinos for various configurations.
