We explore the Beautiful Mirrors model, which aims to explain the measured value of Ab FB, discrepant at the 2.9 sigma level. This scenario introduces vector-like quarks which mix with the bottom, subtly affecting its coupling to the Z. The spectrum of the new particles consists of two bottom-like quarks and a charge -4/3 quark, all of which have electroweak interactions with the third generation. We explore the phenomenology and discovery reach for these new particles at the LHC, exploring single mirror quark production modes whose rates are proportional to the same mixing parameters which resolve the A(FB)(b) anomaly. We find that for mirror quark masses less than or similar to 500 GeV, a 14 TeV LHC with 300 fb(-1) is required to reasonably establish the scenario and extract the relevant mixing parameters.
