摘要:

在本文中,我们研究非标准中微子相互作用的物理学超越标准模型的一个例子,在超级神冈I(1996-2001)和II(2003-2005)期间收集的大气中微子数据。我们专注于口味变化的中性电流(FCNC),它允许中微子口味通过中性电流相互作用的转变,和影响违反轻子非普适性(NU),并引起不同的中性电流相互作用的振幅为不同的中微子口味。我们得到了FCNC耦合参数varepsilon_{mu tau}的极限,|varepsilon_{mu tau}| <1.1 x 10^{-2}(90% C.L.)以及对作为NU耦合varepsilon_{e e}的函数的其它FCNC参数的各种约束。我们在Super-Kamiokande大气数据中没有发现非标准中微子相互作用的证据。

英文摘要:

In this paper we study non-standard neutrino interactions as an example of physics beyond the standard model using atmospheric neutrino data collected during the Super-Kamiokande I(1996-2001) and II(2003-2005) periods. We focus on flavor-changing-neutral-currents (FCNC), which allow neutrino flavor transitions via neutral current interactions, and effects which violate lepton non-universality (NU) and give rise to different neutral-current interaction-amplitudes for different neutrino flavors. We obtain a limit on the FCNC coupling parameter, varepsilon_{mu tau}, |varepsilon_{mu tau}|<1.1 x 10^{-2} at 90%C.L. and various constraints on other FCNC parameters as a function of the NU coupling, varepsilon_{e e}. We find no evidence of non-standard neutrino interactions in the Super-Kamiokande atmospheric data.
