标题： Probing new physics with atmospheric neutrinos at KM3NeT-ORCA

摘要： 我们介绍了利用大气中微子进行ORCA搜索新物理现象的前景。 重点是考虑扩展模型（如惰性中微子和非标准相互作用）对大气中微子振荡的强物质效应的影响。 在存在与活性中微子混合的轻惰性中微子的情况下，不同能量下可能会出现额外的共振和抑制。 还可以利用中微子振荡来探测相干前向散射的特性，这些特性可能因超出标准模型的新相互作用而改变。 初步研究表明，ORCA能够以比当前限制高一个数量级的灵敏度探测这些模型的一些参数。 显示英文摘要

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.
