Measurement of Forward-backward Asymmetry with Muon Pairs via Z/gamma* at 7 TeV in CMS

We present the first measurement of the forward-backward asymmetry AFB for muon pairs produced via an intermediate Z/gamma* at 7 TeV in the CMS experiment. Our results are based on an integrated luminosity of 198 1/nb. The uncorrected forward-backward asymmetry is measured to be -0.50+/-0.40 in the...

description We present the first measurement of the forward-backward asymmetry AFB for muon pairs produced via an intermediate Z/gamma* at 7 TeV in the CMS experiment. Our results are based on an integrated luminosity of 198 1/nb. The uncorrected forward-backward asymmetry is measured to be -0.50+/-0.40 in the mass range 40-70 GeV, and 0.14+/-0.11 in the mass range 70-110 GeV. The measured values are consistent with POWHEG + PYTHIA + full CMS simulation predictions of -0.03 and 0.01 in these two mass bins.
