Description
It is well know that the Zbb anomalous couplings have a long-standing discrepancy between the precision measurement of the electroweak data at the LEP/SLC and the Standard Model prediction, and the Zbb couplings can not be fully determined by the global analysis of the LEP and SLC data. It has been shown that there are two possible solutions for the Zbb couplings after combing the Ab, Rb and AFB measurements at the Z-pole and off Z-pole. Breaking the degeneracy and as well as confirming or excluding the anomaly of AFB measurement at LEP is one of the major tasks of the particle physics. In this talk, I will discuss the recent development of deteriming the Zbb anomalous couplings at the LHC and EIC. It shows that the apparent degeneracy of the Zbb couplings and AFB puzzle could be resolved by those new measurements.
