希格斯现象学作为无菌中微子的探测器

Higgs phenomenology as a probe of sterile neutrinos

Jonathan M. Butterworth, Mikael Chala, Christoph Englert, Michael Spannowsky, Arsenii Titov

摘要:

超越标准模型的物理学可以表现为新的轻态和重自由度。在本文中,我们假设前者只包含一个不育中微子,$N$。因此,对新物理学最不可知的描述是建立在标准模型场和$N$基础上的有效场论。我们表明,希格斯现象学提供了一个敏感的和潜在的关键工具,以限制有效的规范相互作用的不育中微子,目前的实验尚未探测。与此同时,这激发了一系列新的希格斯衰变通道,这些通道具有干净的签名,作为下一次大型强子对撞机运行的候选者,包括$h\to γ+p_T^\text{miss}$和$h\to γγ+p_T^\text{miss}$。

英文摘要:

Physics beyond the Standard Model can manifest itself as both new light states and heavy degrees of freedom. In this paper, we assume that the former comprise only a sterile neutrino, $N$. Therefore, the most agnostic description of the new physics is given by an effective field theory built upon the Standard Model fields as well as $N$. We show that Higgs phenomenology provides a sensitive and potentially crucial tool to constrain effective gauge interactions of sterile neutrinos, not yet probed by current experiments. In parallel, this motivates a range of new Higgs decay channels with clean signatures as candidates for the next LHC runs, including $h\to γ+p_T^\text{miss}$ and $h\to γγ+p_T^\text{miss}$.
