Some new physics models, such as “beautiful mirrors” scenario, predict the existence of the bottom partner B′. Considering the constraints from the data for the Z→bb¯ branching ratio Rband the FB asymmetry AFBbon the relevant free parameters, we calculate the contributions of B′to the cross section σ(Zb) and the Z polarization asymmetry AZfor Zb production at the LHC. We find that the bottom partner B′can generate significant corrections to σ(Zb) and AZ, which might be detected in near future.
