## Abstract

Cross sections of reference trigger processes were obtained based on beam property measurements in dedicated luminosity calibration experiments (van der Meer scans). These cross-sections are essential for absolute cross section determinations of physics processes. The reference cross sections are presented for pp collisions at two center of mass energies; 2.76 TeV and 7 TeV, and for Pb-Pb collisions at 2.76 TeV together with a discussion of the systematic uncertainty originating from beam intensity and rate measurement uncertainties.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
