论文摘要

类似Modaron的玻色子将通过中微子合并从超新星(Sn)核心出现,形式为$νν\ toϕ $和$ \barν\barν\ tox $,带有100 mev范围的能量。随后的所有口味的(抗)中微子的腐烂提供了一个磁通成分,其能量远大于“中微子球”的通常通量。 SN 1987a的Kamiokande-II和Irvine-Michigan-Brookhaven信号中没有100个MEV范围事件,这意味着,少于总能量的不到1%被发出,并提供了对Modaron-Neutrino的最大限制,对$ G \ g \ limesssim sime simssim simsim sims 10^{ - 9}} $ _ $ _ $ 100〜 {\ rm ev} \ sillsim m_ϕ \ sillesim 100〜 {\ rm mev} $。将我们的新论点扩展到其他假设有虚弱的相互作用粒子是很简单的。

Majoron-like bosons would emerge from a supernova (SN) core by neutrino coalescence of the form $νν\toϕ$ and $\barν\barν\toϕ$ with 100 MeV-range energies. Subsequent decays to (anti)neutrinos of all flavors provide a flux component with energies much larger than the usual flux from the "neutrino sphere." The absence of 100 MeV-range events in the Kamiokande-II and Irvine-Michigan-Brookhaven signal of SN 1987A implies that less than 1% of the total energy was thus emitted and provides the strongest constraint on the Majoron-neutrino coupling of $g\lesssim 10^{-9}\,{\rm MeV}/m_ϕ$ for $100~{\rm eV}\lesssim m_ϕ\lesssim 100~{\rm MeV}$. It is straightforward to extend our new argument to other hypothetical feebly interacting particles.
