AI总结:

本文评估 FPF 多个中微子实验通过中性流和带电流 νN 散射探测矢量轻子夸克 U1 的质量覆盖,发现 FLArE(100 吨)灵敏度最佳。

摘要:

在本研究中,我们利用中微子–核子散射(νN → νN′ 和 νN → lN′),计算了 Forward Physics Facility(FPF)拟建实验对矢量轻子夸克(LQ)U1 的灵敏度覆盖范围,这些实验包括 FASERν、FASERν2、FLArE(10 吨)和 FLArE(100 吨)。我们覆盖了 10^-3 GeV ≤ M_LQ ≤ 10^4 GeV 的宽质量范围。新结果表明,FLArE(100 吨)对该 LQ 模型提供最佳灵敏度。所有实验的灵敏度曲线遵循相似模式:随着 LQ 质量增加,灵敏度减弱。我们结合了从中微子中性流和带电流相互作用获得的灵敏度。

英文摘要:

In this study, we calculate the sensitivity reach on the vector leptoquark (LQ) $U_1$ at the experiments proposed in Forward Physics Facility (FPF), including FASER$ν$, FASER$\nu2$, FLArE (10 tons), and FLArE (100 tons) using the neutrino-nucleon scattering ($νN \rightarrow νN'$ and $νN \rightarrow l N'$). We cover a wide mass range of $10^{-3}$ GeV $\leq M_{LQ}\leq 10^4$ GeV. The new result shows that the FLArE (100 tons) offers the best sensitivity to the LQ model. The sensitivity curves for all the experiments follow a similar pattern with weakened sensitivities with the increment of the LQ mass. We combine the sensitivities obtained from the neutral- and charged-current interactions of the neutrinos.
