Standard Model fit: inclusive vs exclusive

exclusive only:
- rhobar-etabar planes with all the constraints: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/semilep/all_exclusive_postEPS11.eps
- sin2beta compatibility plot: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/semilep/pull_sin2bfit3_exclusive.eps
  - sin2beta from the rest of the fit: sin2beta = 0.706 +/- 0.041 corresponding to a difference of ~0.8 sigma with respect to the experimental value
inclusive only:
- rhobar-etabar planes with all the constraints: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/semilep/all_inclusive_postEPS11.eps
- sin2beta compatibility plot: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/semilep/pull_sin2bfit3_inclusive.eps
  - sin2beta from the rest of the fit: sin2beta = 0.791 +/- 0.041 corresponding to a difference of ~2.6 sigma with respect to the experimental value

sin2beta predictions: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/sin2beta_nosemileptonic.eps

inputs used	sin2beta value	sigmas from the experimental value
no semileptonic (no Vub or Vcb)	0.76 +/- 0.10	0.9
exclusive only	0.706 +/- 0.041	0.8
inclusive only	0.791 +/- 0.041	2.6

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
