长基线中微子实验中非标准相互作用参数的约束

Constraining the non-standard interaction parameters in long baseline neutrino experiments

Katri Huitu, Timo J. Kärkkäinen, Jukka Maalampi, Sampsa Vihonen

摘要:

本文研究了在长基线中微子振荡实验中探测可能的非标准中微子相互作用强度的前景。我们发现,这些实验是敏感的NSI耦合下降到0.01-0.1的水平取决于振荡通道和基线长度,以及对探测器的基准质量。我们还研究了轻子CP角$δ_{CP}$对NSI耦合约束的干扰。发现在$ν_{e}\leftrightarrowν_μ$和$ν_{e}\leftrightarrowν_τ$跃迁的情况下干扰很强,而在其它跃迁中干扰不明显。在我们的数值分析中,我们应用GLoBES软件,并使用LBNO设置作为我们的基准。

英文摘要:

In this article we investigate the prospects for probing the strength of the possible non-standard neutrino interactions (NSI) in long baseline neutrino oscillation experiments. We find that these experiments are sensitive to NSI couplings down to the level of 0.01-0.1 depending on the oscillation channel and the baseline length, as well as on the detector's fiducial mass. We also investigate the interference of the leptonic CP angle $δ_{CP}$ with the constraining of the NSI couplings. It is found that the interference is strong in the case of the $ν_{e}\leftrightarrowν_μ$ and $ν_{e}\leftrightarrowν_τ$ transitions but not significant in other transitions. In our numerical analysis we apply the GLoBES software and use the LBNO setup as our benchmark.
