CMS Z (mumu) yields for comparisons with ATLAS using 2012 data

For the purpose of checking and monitoring the luminosity delivered to experiments CMS and ATLAS agree(d) on common criteria and datasets (Fills) to measure the yields of standard model processes, in particular Z boson decays to muons. This document contains the information about the final deliverable, efficiency corrected Z(mumu) yield, which is proportional to the integrated luminosity in each of 17 common samples chosen for 2012 data. The achieved precision per Fill is better than 1.5 per cent.
