Sumario:The LHC luminosity model developed to describe and follow the evolution of the machine luminosity is presented and compared to 2017 data. The model is based on the main mechanisms of luminosity degradation, such as intrabeam scattering, synchrotron radiation, elastic scattering and luminosity burn-off. It was initially introduced for the 2016 run. For the 2017 run, the model estimates are compared with data at the Flat Bottom (450 GeV) and Flat Top (6.5 TeV) energies. The evolution of the emittance and beam lifetime are presented for the entire 2017 run, and the results are compared to the 2016 observations.
