The Standard Model has been highly successful in explaining the results of all laboratory experiments to date yet astrophysical evidence for dark matter and dark energy together strongly suggests that this model is not the complete story. Indeed, the Standard Model has theoretical problems when it is extrapolated to the TeV scale. Precision studies of the B-meson at B factories and collider experiments at the TEVatron at Fermilab and the Large Hadron Collider (LHC) at CERN represent two complimentary strategies to search for physics beyond the Standard Model. The precision study of B-meson decays can identify signals of new physics. In particular CP violation in B-meson decays is strongly constrained in the Standard Model so signals of new physics may be very evident in CP-odd observables. At the LHC, the particle content of new physics can potentially be directly observed. In this colloquium I will give some examples which illustrate the complementary nature of precision studies in B-decay and collider experiments at the LHC. This will give some insight into the relative strengths and weaknesses of the two approaches.
