论文摘要
我们研究了中微子与新的轻中性量表玻色子的耦合，$ z^\ prime $，在Faser $ν$实验中的质量小于500 {\ rm MeV}。在许多情况下，旨在解释粒子物理学和宇宙学中各种异常的情况，将轻量表玻色子耦合到中微子的场景是在许多情况下进行的。 This interaction leads to a new decay mode for charged mesons to a light lepton plus neutrino and $Z^{\prime}$, ($π^+(K^+)\to e^+ νZ^\prime$) followed by the subsequent decay of $Z^\prime$ into the pair of neutrino and anti-neutrino, ($Z^\prime \to ν\barν$). LHC的前向搜索实验Faser $ν$有可能首次检测对撞机中微子。特别是，Faser $ν$乳液检测器将为检测$τ$ -Neutrinos和测量其能量提供机会。利用Faser $ν$乳液检测器的这种能力，我们研究了Faser $ν$实验的潜力以及该实验的升级版本Faser2 $ν$的升级版本，以限制中微子与轻量表玻色子的耦合。
We study the impact of the coupling of neutrinos with a new light neutral gauge boson, $Z^\prime$, with a mass of less than 500 {\rm MeV} in FASER$ν$ experiment. Scenarios in which a light gauge boson is coupled to neutrinos are motivated within numerous contexts which are designed to explain various anomalies in particle physics and cosmology. This interaction leads to a new decay mode for charged mesons to a light lepton plus neutrino and $Z^{\prime}$, ($π^+(K^+)\to e^+ νZ^\prime$) followed by the subsequent decay of $Z^\prime$ into the pair of neutrino and anti-neutrino, ($Z^\prime \to ν\barν$). FASER$ν$, the Forward Search Experiment at the LHC, has the potential to detect collider neutrinos for the first time. In particular, the FASER$ν$ emulsion detector will provide the opportunity to detect $τ$-neutrinos and to measure their energies. Using this ability of FASER$ν$ emulsion detector, we investigate the potential of FASER$ν$ experiment and the proposed upgraded version of this experiment, FASER2$ν$, to constrain the coupling of a neutrino with the light gauge boson.
