B-Physics at the LHC

Abstract

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

Dawn or dusk? Flavour physics in the hadron collider era

“…7, where the RICH is used to distinguish between B → Dπ and B → DK decays. Already with a 1 fb −1 dataset it should prove possible to improve on many of the measurements performed at the B-factories [41].…”
