Description
Accurate luminosity calibration is essential for precise cross-section measurements and reliable machine performance optimization. In colliders with several interaction points, the cumulative beam–beam effects depend on the number of collision partners of individual bunches, which can bias luminosity calibration if not properly accounted for. To investigate this experimentally, a dedicated beam–beam experiment was performed at the LHC using tune scaling to mimic configurations with multiple collision partners within a single interaction region. By adjusting the fractional tunes, while preserving comparable beam–beam parameters, the dependence of luminosity calibration corrections on the effective number of collisions was systematically studied. The results are compared with expectations from numerical simulations, supporting the use of tune scaling as a valid strategy to reproduce multi-collision conditions for luminosity calibration corrections.
