标准模型超弱U(1)扩展的中微子和规范参数的实验约束

Experimental constraints on the neutrino and gauge parameters of the super-weak U(1) extension of the standard model

Timo J. Kärkkäinen, Zoltán Trócsányi

摘要:

超弱力是标准模型(SM)的最小的、无反常的U(1)扩展,旨在解释(i)中微子质量和混合矩阵元的起源,(ii)暗物质,(iii)宇宙暴胀,(iv)电弱真空的稳定性和(v)稀薄起源。我们详细讨论了该模型的中微子扇区,并研究了中微子Yukawa矩阵和混合矩阵元的允许参数空间。该模型产生非标准的中微子相互作用,其允许的实验极限被用来约束模型的参数空间。我们提供的基准点,在相关的参数空间内的SHiP和MATHUSLA实验的灵敏度范围内。

英文摘要:

The super-weak force is a minimal, anomaly-free U(1) extension of the standard model (SM), designed to explain the origin of (i) neutrino masses and mixing matrix elements, (ii) dark matter, (iii) cosmic inflation, (iv) stabilization of the electroweak vacuum and (v) leptogenesis. We discuss the neutrino sector of this model in detail and study the allowed parameter space of the neutrino Yukawa matrices and mixing matrix elements. The model generates nonstandard neutrino interactions, whose allowed experimental limits are used to constrain the parameter space of the model. We provide benchmark points in the relevant parameter space that fall within the sensitivity region of the SHiP and MATHUSLA experiments.
