| 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. | Calorimeter calibration establishes the relationship between the measured energy deposited in a detector and the true energy of incident particles. Precise calibration is essential for physics measurements, Higgs boson properties, and new physics searches at colliders, requiring careful control of systematic uncertainties. |
