Non factorisation in ATLAS and ALICE vdM scans: experience in Run 2, impact on luminosity calibration

The original vdM formalism assumes that the particle densities in each bunch can be factorised into independent horizontal and vertical components. The effect of violations of this assumption (non-factorisation) can be quantified by performing dedicated measurements during Run 2 vdM scan sessions of...

description The original vdM formalism assumes that the particle densities in each bunch can be factorised into independent horizontal and vertical components. The effect of violations of this assumption (non-factorisation) can be quantified by performing dedicated measurements during Run 2 vdM scan sessions of the ATLAS and the ALICE detectors. In both experiments, this is done by observing and modelling the evolution of various beamspot phenomena during the scans.
