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 s 0 → μ + μ − and B d 0 → K ∗ 0 μ + μ − ; measurements of the CKM angle γ ; measurements of the B s 0 mixing phase ϕ s ; and measurements of radiative penguin decays B 0 → s γ .
