The LHCb upgrade detector

The LHCb experiment has been designed to perform precision measurements of CP asymmetries and to investigate potential effects of physics beyond the Standard Model. Results obtained from data collected in 2010 and 2011 show that the detector is robust and functioning well. While LHCb will be able to measure a host of interesting channels in heavy flavour decays in the coming years, a limit of about 1-2 fb−1 of data per year can only be overcome by upgrading the detector. With a detector read out at 40 MHz, a much more flexible software-based triggering strategy will allow a large increase not only in the data rate, as the detector will collect 5 fb−1 per year, but also in the ability to increase trigger efficiencies especially in decays to hadronic final states. In addition, it will be possible to modify trigger algorithms in order to explore different physics as LHC discoveries point to the most interesting channels. Here a short description of the physics motivations and proposed detector changes for exploring new phenomena in proton-proton collisions near 14 TeV centre-of-mass energy are presented.
