STUDY OF THE RELATIVE LHC BUNCH POPULATIONS FOR LUMINOSITY CALIBRATION

An important aspect of luminosity calibration measurements is the bunch population product normalization. In the case of the LHC, the treatment of this normalization can be split into three subjects: the total current measurement, the corrections from the non-perfect longitudinal distribution and th...

Sumario:An important aspect of luminosity calibration measurements is the bunch population product normalization. In the case of the LHC, the treatment of this normalization can be split into three subjects: the total current measurement, the corrections from the non-perfect longitudinal distribution and the relative amplitude of the individual bunch populations. In this note, the last item is discussed in detail and in the context of the 2010 and 2011 luminosity calibration measurements performed for each LHC Interaction Point. The various measurement methods of the relative bunch populations are reviewed and the impact of their uncertainties on the cross section normalization are analyzed.
