Presentation Transcript

  1. Life beyond A_FB

  2. Possible Extensions • Deviations from SM will appear in several different ways. • Measurement of Q_T is classic and solid physics. The issue is still alive and the LHC will have to contribute to it. • Unparticle signal in Z->ffU will manifest in differential cross section and asymmetry(?) • In Z+jets (Z+n*jets, n=1,2,3,…), the Z decay asymmetry is an indication of new physics. New calculations in W+n*j suggest strong BSM features
