Abstract: The LHCb experiment, a single-arm forward spectrometer designed for the study of beauty and charm decays, operated successfully through the end of the Large Hadron Collider (LHC) Run 2. During this period, it collected data that resulted in numerous discoveries, challenging the boundaries of the Standard Model (SM) of particle physics and providing opportunities to explore potential new physics beyond it. During Run 3, the detector has been upgraded to run at higher instantaneous luminosity and collect large datasets, since most of the current measurements are statistically limited. Most of the LHCb subdetectors had increased the radiation hardness, the readout speed and their granularity. To fully exploit the higher luminosity delivered by the LHC, the hardware trigger has been replaced by a software trigger operating online and allowing for more flexible and complete trigger decisions. This document discusses the key features and first performances of the newly installed detector. A perspective about the future upgrades beyond Run 4, known as Upgrade II, will be provided.
