论文摘要

在超新星中产生的新的光颗粒会导致额外的能量损失,并导致中微子产生与超级新星1987a(SN1987A)相冲突的中微子产生的不足。与以前的SN1987A研究中的大多数相反,我们研究了$ z'$玻色子,轴和类似轴的颗粒(阿尔普斯)与SN1987A中产生的MUON相互作用的影响。我们第一次发现对耦合MUON的通用$ z'U骨的限制,并将我们的结果应用于粒子模型,包括尺寸$l_μ-l_τ$,$ u(1)_ {l_μ-l_τ} $,以及$ b-l $ $ u(b-l $ u(1)_ {b-u(1)_ {b-l-l} $。我们将质量约为250-500 mev的$ z'$玻色子限制,然后在$ z'$ - muon耦合中降低至$ 10^{ - 9} $。我们还通过检查环路级相互作用的重要性以及在更广泛的轴突质量范围内执行计算,从而扩展了对轴突耦合的先前工作。我们将MUON耦合的轴从任意低质量限制为约200-500 MEV,范围延伸到轴线耦合,约为$ 10^{ - 8} $ GEV $^{ - 1} $。我们得出的结论是,超新星广泛地提供了与MUON相互作用的新的轻耦合颗粒的敏感探针。

New light particles produced in supernovae can lead to additional energy loss and a consequent deficit in neutrino production in conflict with the neutrinos observed from Supernova 1987A (SN1987A). Contrary to the majority of previous SN1987A studies, we examine the impact of $Z'$ bosons, axions, and axion-like particles (ALPs) interacting with the muons produced in SN1987A. For the first time, we find constraints on generic $Z'$ bosons coupled to muons, and apply our results to particle models including gauged $L_μ-L_τ$ number, $U(1)_{L_μ-L_τ}$, and gauged $B-L$ number, $U(1)_{B-L}$. We constrain $Z'$ bosons with masses up to about 250-500 MeV, and down to about $10^{-9}$ in $Z'$-muon coupling. We also extend previous work on axion-muon couplings by examining the importance of loop-level interactions, as well as performing calculations over a wider range of axion masses. We constrain muon-coupled axions from arbitrarily low masses up to about 200-500 MeV, with bounds extending down to axion-muon couplings of approximately $10^{-8}$ GeV$^{-1}$. We conclude that supernovae broadly provide a sensitive probe of new lightly-coupled particles interacting with muons.
