在KM3NeT-ORCA用大气中微子探测新物理

Probing new physics with atmospheric neutrinos at KM3NeT-ORCA

Joao A. B. Coelho

摘要:

展望了ORCA利用大气中微子研究新物理现象的前景。重点是利用强物质效应对大气中微子振荡的影响,根据扩展的模型,如不育中微子和非标准相互作用。在存在与活跃中微子混合的轻无菌中微子时,可能会发生不同能量的额外共振和Supplement。人们也可以使用中微子振荡来探测相干前向散射的性质,这些性质可能会被标准模型之外的新相互作用所改变。初步研究表明,ORCA将能够探测这些模型的一些参数,其灵敏度比目前的限制高出一个数量级。

英文摘要:

We present the prospects of ORCA searches for new physics phenomena using atmospheric neutrinos. Focus is given to exploiting the impact of strong matter effects on the oscillation of atmospheric neutrinos in light of expanded models, such as sterile neutrinos and non-standard interactions. In the presence of light sterile neutrinos that mix with active neutrinos, additional resonances and suppressions may occur at different energies. One may also use neutrino oscillations to probe the properties of the coherent forward scattering which may be altered by new interactions beyond the Standard Model. Preliminary studies show that ORCA would be able to probe some parameters of these models with sensitivity up to one order of magnitude better than current constraints.
