Abstract
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 Rb and the FB asymmetry AFBb on the relevant free parameters, we calculate the contributions of B′ to the cross section σ(Zb) and the Z polarization asymmetry AZ for 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.
