Absolute Calibration of the Luminosity Measurement at CMS: Winter 2012 Update

A method for determination of offline luminosity based on pixel cluster counting is described. The method starts with the determination of the pixel cluster cross section, $\sigma_{\mathrm{pixel}}$, using a Van der Meer scan.

Sumario:A method for determination of offline luminosity based on pixel cluster counting is described. The method starts with the determination of the pixel cluster cross section, $\sigma_{\mathrm{pixel}}$, using a Van der Meer scan. Having thus established a value for $\sigma_{\mathrm{pixel}}$, the luminosity for a given luminosity section can be determined by counting the number of pixel clusters per zero-bias trigger.
