大型对撞机上新的中微子相互作用

New neutrino interactions at large colliders

Francisco del Aguila, Juan Antonio Aguilar-Saavedra, Jorge de Blas

摘要:

本文更新了μ介子衰变中产生的中微子螺旋度的现有界限,包括e+ e-> fbar f LEP 2数据.这大大降低了从所有其他电弱精度数据得出的极限。在标准模型的扩展中,为了在这样的衰变中最大化RH中微子的产生,最终在中微子工厂的近距离探测器中可观察到的中微子赤字可以达到5%的数量级。出于目前的大型强子对撞机运行在7 TeV,我们还更新了以前的工作,提供发现限制在这个中心的质量能量的跷跷板介质。可以发现能量为200 GeV的轻子三重态,其亮度为1 ~ 1.5 fb^-1。在0.75 - 3 fb^-1的情况下,可以看到相同质量的标量三重态。是什么让他们的搜索在第一次LHC分析中也很有吸引力。

英文摘要:

We update present bounds on the helicity of the neutrinos produced in muon decay, including e+ e- -> fbar f LEP 2 data. These significantly reduce the limits derived from all the other electroweak precision data. In Standard Model extensions designed to maximize the RH neutrino production in such a decay the neutrino deficit eventually observable in a near detector at a neutrino factory can be of the order of 5 %. Motivated by the current LHC run at 7 TeV, we also update previous work providing discovery limits on see-saw mediators at this centre of mass energy. Lepton triplets with 200 GeV could be discovered with luminosities of 1 - 1.5 fb^-1. Scalar triplets of the same mass might be seen with 0.75 - 3 fb^-1. What makes their search also attractive in the first LHC analyses.
