B-Physics at the LHC

Data which will be taken at the Large Hadron Collider (LHC) will allow a rich programme of B-physics studies to be carried out, both at LHCb, LHC's dedicated heavy flavour experiment, and at ATLAS and CMS. The aim of these studies is to over-constrain the CKM matrix in order to search for New Physics in the flavour sector. This contribution gives an overview of the B-physics programme at the LHC. The detectors are introduced in the context of the LHC's likely 2009 running conditions, and certain outstanding issues in B-physics are reviewed. Four areas of the LHC's B-physics programme are looked at in more detail: measurements of rare decay processes $B^0_s \rightarrow \mu^+\mu^-$ and $B^0_d\rightarrow K^{*0} \mu^+\mu^-$; measurements of the CKM angle $\gamma$; measurements of the $B^0_s$ mixing phase $\phi_s$; and measurements of radiative penguin decays $B^0\rightarrow s\gamma$.
