HFAG averages

B factories: Afs measurement using Bd

Tevatron: Afs measurement using Bs and/or Bd

  • CDF, Note 9015
  • method: dilepton sample
  • measured Ab {~(Afs(s)+Afs(d))/2}: +0.0080 +/- 0.0090(stat) +/- 0.0068(syst)

  • , arXiv:0904.3907v2 PRD 82, 012003 (2010)
  • method: time-dependent, using tagging and partially reconstructed (like we want to do in LHCb)
  • measured Afs(s): -0.0017 +/- 0.0091(stat) +/- 0.0015(syst)

  • , hep-ex 1106.6308 Phys. Rev. D 84, 052007 (2011)
  • Measurement of the anomalous like-sign dimuon charge asymmetry with 9  fb-1 of pp collisions
  • method: use two samples of very loosely selected events which have a lot of background components in common and subtracted both measurements
  • measured Ab {~(Afs(s)+Afs(d))/2}: (-0.787±0.172(stat)±0.093(syst))%
  • comprehensive overview of method

  • , arXiv:1207.1769
  • 10fb-1, method: time-dependent, partially reconstructed
  • measured Afs(s): -0.0108 +/- 0.0072(stat) +/- 0.0017(syst)

  • , arXiv:1208.5813
  • 10fb-1, method: time-dependent, partially reconstructed
  • measured Afs(d): +0.0068 +/- 0.0045(stat) +/- 0.0014(syst)
