LHCb Upgrade Plans
Abstract
The LHCb experiment will operate for about five years at a luminosity of 2x1032 cm-2 s-1 and plans are to accumulate a data sample of ~10 fb-1. Here we present the physics programme and detector design for a future high luminosity phase of the LHCb experiment. An upgraded LHCb experiment would operate at ten times the design luminosity, i.e. at ~2x1033 cm-2 s-1 and aims to collect a data sample of ~100 fb-1 over five years. This programme would allow the probe of new physics at an unprecedented level. Key measurements include the B0s mixing phase phis in B0s -> J/ phi and B0s -> phi phi decays with a significant sensitivity to the small Standard Model prediction and a very precise measurement of the CKM angle gamma in tree diagram decays. Initial studies of the modified LHCb trigger and detectors are presented. The upgraded LHCb experiment can run with or without an LHC luminosity upgrade.
