SM update

• Standard Model fit updates:

  • rhobar-etabar plane with all the constraints: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/all_postEPS11.eps

    • numerical results:

      parameter	fit output
      rhobar	0.132 +/- 0.020
      etabar	0.353 +/- 0.014
      alpha	88 +/- 3
      beta	22 +/- 1
      gamma	69 +/- 3

  • rhobar-etabar plane using angles only: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/angles_postEPS11.eps

    • parameter	fit output
      rhobar	0.129 +/- 0.027
      etabar	0.340 +/- 0.016

  • rhobar-etabar plane not using angles (sides and epsk): http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/sides_postEPS11.eps

    • parameter	fit output
      rhobar	0.155 +/- 0.038

  • compatibility plots: .to “measure” the agreement of a single measurement with the indirect determination from the fit using all the other inputs:
    • Color code: agreement between the predicted values and the measurements at better than 1, 2, ...nsigma.//
      • The cross has the coordinates (x,y)=(central value, error) of the direct measurement
