To resolve the long-standing discrepancy between the precision measurement of bottom quark forward-backward asymmetry at LEP/SLC and the Standard Model prediction, we propose a novel method to probe the $Zb\bar{b}$ coupling by measuring the single-spin asymmetry $A_e^b$ of the polarized lepton cross section in neutral current DIS processes with a $b$-tagged jet at HERA and EIC. Depending on the tagging efficiency of the final state $b$-jet, the measurement of $A_e^b$ at HERA can already partially break the degeneracy found in the anomalous $Zb\bar{b}$ coupling, as implied by the LEP and SLC precision electroweak data. In the first year run of the EIC, the measurement of $A_e^b$ can already break the degeneracy, due to its much larger luminosity and higher electron beam polarization. With enough integrated luminosity collected at the EIC, it is possible to either verify or exclude the LEP data and resolve the $A_{\rm FB}^b$ puzzle. We also discuss the complementary roles between the proposed $A_e^b$ measurement at EIC and the measurement of $gg \to Zh$ cross section at the HL-LHC in constraining the anomalous $Zb\bar{b}$ coupling.

我们利用螺旋度抑制反应$e_R p \rightarrow νX $研究HERA对新物理的敏感性，其中最终中微子可以是标准模型中微子或重中微子。该方法是模型无关的，是基于一个有效的拉格朗日参数化。它表明，HERA将把新物理的规模显着的界限，虽然，在一般情况下，这些都比以前认为的更温和。如果在上述过程中观察到与标准模型的偏差，那么未来的对撞机（例如SSC和LHC）将能够直接探测造成这些偏差的物理原因}

HERA high $Q^2$ events as indications of excited leptons with weak isotopic spin 3/2
H1和ZEUS反常事件被解释为激发态轻子$E$的产生和衰变，它对应于第一代轻子二重态（$ν_e, e$）与W三重态的自旋1/2共振。这一假设通过考虑阶梯近似下的Bethe-Salpeter方程得到了支持。对于零质量态，存在弱同位旋$I = 3/2$解，即M_E $ is small in comparison with TeV mass scale. The coupling of $ E $ with leptons and $ W $ is defined by the normalization condition. Calculation of the $ E $ width and the production cross-sections agrees with HERA data for value of the triple $ W $ coupling constant $ λ \simeq 0.5$.不同渠道的同位素关系作为一种工具，检查解释。
