论文摘要
我们提出了标准模型的简单扩展,该模型导致可重新分配的远程矢量介导的中微子自我互动。该模型可以通过在重组过程中延迟中微子自由流的发作来解决哈勃张力,而不会与其他测量值冲突。扩展的量规,标量和中微子扇区导致可观察到的签名,包括无形的希格斯和$ z $衰减,从而将哈勃张力与LHC和未来颜色的精确度量联系起来。该型号具有新的中性粒细节仪,带有$ M_ {Z'} \ sim \ Mathcal {O}(10〜 \ Mathrm {ev})$,并以几美元的higgses向希格斯(Higgses)支付了几美元〜\ mathrm {gev} $。它需要隐藏的中微子,具有大于$ 5 \ times10^{ - 4} $的活动中的混合角度,以及$ 1 \ div300 \ div300 \ mathrm {ev} $的群众,这也可能对短台中性中微子振荡异常起作用。
We present a simple extension of the Standard Model that leads to renormalizable long-range vector-mediated neutrino self-interactions. This model can resolve the Hubble tension by delaying the onset of neutrino free-streaming during recombination, without conflicting with other measurements. The extended gauge, scalar and neutrino sectors lead to observable signatures, including invisible Higgs and $Z$ decays, thereby relating the Hubble tension to precision measurements at the LHC and future colliders. The model has a new neutrinophilic gauge boson with $m_{Z'}\sim\mathcal{O}(10~\mathrm{eV})$ and charged Higgses at a few $100~\mathrm{GeV}$. It requires hidden neutrinos with active-hidden mixing angles larger than $5\times10^{-4}$ and masses in the range $1\div300\mathrm{eV}$, which could also play a role for short baseline neutrino oscillation anomalies.
