概要	The Van der Meer scan is a precision measurement technique for determining the absolute luminosity at particle colliders by mechanically separating the colliding beams and measuring the collision rate as a function of beam separation. This fundamental calibration is essential for all cross-section measurements and physics analyses at the LHC and other hadron colliders.	Track reconstruction is the process of identifying and measuring the trajectories of charged particles through a detector, providing momentum and impact parameter information essential for particle identification, vertex reconstruction, and physics analysis in high-energy physics experiments.
