Experimental prospects for B physics and discrete symmetries at LHC and future projects

The experimental prospects for B physics (with brief mentions of charm and τ physics) at the Large Hadron Collider experiments are reviewed, with particular attention to the LHCb experiment. The main focus is on CP (a)symmetry, though the usefulness of rare decays to probe the symmetries of nature is also discussed. The need for upgrades and new facilities to continue the investigations beyond the first few years of LHC operations is emphasised.
