The LHCb Upgrade

Future flavour physics experiments will be required in the second half of the next decade to either elucidate the flavour structure of new particles discovered at the LHC or to probe new physics at the multi-TeV scale. The planned upgrade of the LHCb detector involves at least five year of operating at ten times the current design luminosity, i.e. at about 2x10$^33$cm$^{-2}$s$^{-1}$. The aim is to collect a data sample of ~100 fb$^{-1}$ as well as to increase the trigger efficiency for hadronic decays by at least a factor of two. The present paper describes briefly the physics motivation for an LHCb upgrade and the required technologies for the detector working at high luminosity.
