Resumen:
The LEP and SLD experimental measurements of the bottom-quark forward-backward asymmetry suggest deviations from the Standard Model in the Zbbarb couplings. Recently, Tevatron has observed a deviation in the forward-backward asymmetry of the top-quark pair production. I will present a two-site composite Higgs model and I will discuss its capability to improve the agreement with those experimental results as well as its predictions and constraints from LHC.
