Status and Prospects for Heavy Flavour Physics at LHC

The Large Hadron Collider will be a unique place to find new physics in the next decade. A huge production of b and c quarks will allow a rich programme of Heavy Flavour Physics to be carried out either by the multipurpose experiments ATLAS and CMS or by LHCb, the experiment designed for such physics. An overview of the LHC machine and experiments’ performances will be given with the first 201 data. The start-up is very bright and some first LHCb heavy flavour results will be presented. The b physics program at LHC will be illustrated with three examples: the searches for rare decays such as $B_s \rightarrow \mu\mu$, the CP measurements from $B_s \rightarrow /\psi\phi$ and CP measurements of the Cabibbo Kobayashi Maskawa (CKM) angle $\gamma$. Some prospects for an upgrade of the LHCb detector will also be given.
