论文摘要
我们使用右手中微子$ n $（smneft）扩展了一般的狄拉克中微子相互作用，使用深度非弹性和相干的弹性中微子散射，核β衰变和梅森衰减数据以及高能量电子和高能量电子电子和Proton-proton-Proton collider数据扩展。我们计算低能量有效场理论（左）的单循环异常尺寸（左）低于电动量表，而Smneft的smneft则高于电动量表。左和SMNEFT之间的树级匹配是在Electroweak量表上进行的。当前，标量和张量相互作用的最严格限制是由伪级介子腐烂和每米尔级的LHC测量结果产生的。将来，即将到来的高光度LHC（HL-LHC）有可能达到$ 10^{ - 4} $级别，而LHEC在某些理论假设下可以发挥重要作用。
We constrain general Dirac neutrino interactions based on the Standard Model Effective Field Theory framework extended with right-handed neutrinos $N$ (SMNEFT) using deep inelastic and coherent elastic neutrino scattering, nuclear beta decay, and meson decay data, and high energy electron-proton and proton-proton collider data. We compute the one-loop anomalous dimensions of the low-energy effective field theory (LEFT) below the electroweak scale and of SMNEFT above the electroweak scale. The tree-level matching between LEFT and SMNEFT is performed at the electroweak scale. Currently, the most stringent limits on scalar and tensor interactions arise from pseudoscalar meson decays and the LHC measurements at the per mille level. In the future, the upcoming High-Luminosity LHC (HL-LHC) has the potential to reach the $10^{-4}$ level and LHeC can play an important role under certain theoretical assumptions.
