Optimal search reach for heavy neutral leptons at a muon collider

Krzysztof Mękała, Jürgen Reuter, Aleksander Filip Żarnecki

AI总结:

本文比较未来高能μ子与电子对撞机对重惰性中微子的探测能力,证明μ子对撞机在 $Z$ 极点以上至数TeV质量范围具有最远搜索覆盖,并指出二者在味空间的互补性。

摘要:

中微子是已知最难以捉摸的粒子。与标准中微子混合的更重惰性中微子,或许能够解开宇宙重子不对称之谜。在这篇快报中,我们表明,在所有未来的能量前沿加速器中,对于质量范围位于 $Z$ 极点以上并进入多 TeV 区间的此类中微子,μ子对撞机将提供最远的搜索覆盖范围。我们比较了相同机器能量下μ子对撞机与电子对撞机的性能,并简要讨论了两类加速器在味空间中的互补性。

英文摘要:

Neutrinos are the most elusive particles known. Heavier sterile neutrinos mixing with the standard neutrinos might solve the mystery of the baryon asymmetry of the universe. In this letter, we show that among all future energy frontier accelerators, muon colliders will provide the farthest search reach for such neutrinos for mass ranges above the $Z$ pole into the multi-TeV regime. We compare the performance of muon with electron colliders of the same machine energy and briefly discuss the complementarity in flavor space between the two types of accelerators.
