Luminosity Precision Measurements for Hadron Colliders (FCC / LHC-Lumi)
Model and study the impact of beam-beam effect on the luminosity precision measurements. Simulations of multiple interaction points and cross talk between experiments should be explored. Estimate the luminosity uncertainties and benchmark to available data (LHC van der Meer scans). Extend the understanding of luminosity uncertainties to bunch trains for a possible monitoring of the detector performance during operation. Commission and exploit beam monitoring instrumentation at CMS for precision luminosity measurement and for benchmarking of the luminosity models. Contribute to the Run-3 precision luminosity analysis at CMS and detector performance studies on new Fast Beams Conditions Monitor using silicon sensors.
