The LHCb experiment, operating at the CERN Large Hadron Collider, has been
designed to perform high-precision measurements of CP violation and searches for
New Physics using the huge flux of beauty and charmed hadrons produced in
proton-proton collisions at 13TeV collision energy. The LHCb detector is a single-arm
forward spectrometer and shows excellent tracking system and particle
identification capabilities. The detector has operated very smoothly and with
impressive performances during Run1 and is currently taking data during Run2. LHCb
has, and continues to, perform very interesting measurements in the heavy flavor
sector. However, the limit of a few fb−1 of data per year cannot be overcome without
increasing the readout limitation of the detector, which today cannot exceed 1MHz.
The upgraded spectrometer, featuring a 40MHz readout and a much more flexible
fully software-based trigger system, will allow increasing the data rate as well as the
efficiency in particular for hadronic channels, allowing a widening of our physics
scope. In this talk I will present the status of the upgrade work for the various
subsystems, including trigger and DAQ, and I will discuss the discovery potential of
LHCb for Run3 and beyond.
