Numerical results:

A brief document that provides the collection of up-to-date inputs to the global CKM analysis and the numerical results obtained from it. The results include: Wolfenstein parameters, UT angles, (combinations of) CKM elements, theory parameters and rare branching fractions. Detailed background information on the methodology and the treatment of experimental and theoretical uncertainties is provided in hep-ph/0406184.

ΔMs Results

	α,β,γ convention:
Constraints in the (ρ-bar,η-bar) plane with FPCP06 inputs and experimental measurements except ΔMs as of Summer 2005	eps gif
Constraints in the (ρ-bar,η-bar) plane with FPCP06 inputs and experimental measurements except ΔMs as of Moriond 2006 (with D0 result but not CDF result).	eps gif
Constraints in the (ρ-bar,η-bar) plane with FPCP06 inputs and experimental measurements (with D0 and CDF ΔMs results)	eps gif
Comparison between CDF ΔMs measurement and CKM fit w/o ΔMs	eps gif
|Vtd/Vts| from the global fit, the CDF ΔMs measurement and the ratio of the branching fractions (B→ρ0γ / B→K*0 γ) (average of BABAR and Belle)	eps gif

Constraint from the B⁺→τ⁺ ν branching fraction:

	α,β,γ convention:	φ1,φ2,φ3 convention:
Constraint in the (ρ-bar,η-bar) plane from the simultaneous use of the the B+→τ+ν branching fraction and Δmd.	eps gif	eps gif
Constraint in the (ρ-bar,η-bar) plane from the simultaneous use of the the B+→τ+ν branching fraction and Δmd with improved staggered fermions (see hep-lat/0510113).	eps gif
Constraint in the (ρ-bar,η-bar) plane from the simultaneous use of the limit on the B+→τ+ν branching fraction and Δmd. Also shown is the constraint one would obtain by a precise measurement of BR(B+→τ+ν). It illustrates the gain in accuracy obtained from the simultaneous use of the two constraints ( B+→τ+ν and Δmd), where the uncertainty from fB is reduced (it cancels in the ratio).	eps gif	eps gif

Constraints on the angle α/Φ₂ from charmless B decays:

Constraint on α/Φ2 from B→ρρ.	eps gif
Constraints on α/Φ2 from B→ππ, ρπ, ρρ, compared to the prediction from the CKM fit (not including these measurements). α[combined] = 100.2 +15.0/–8.8 deg.	eps gif
The numerical results for these quantities are given in the summary paper

Constraints on the angle γ/Φ₃ from B decays to charm :

Constraints on |sin(2β+γ)|:

Constraints on |sin(2β+γ)| from the measurement of time-dependent CP asymmetries in D(*) π (ρ). Moriond06 HFAG average is used as input. The extraction of the UT angles relies on SU(3) symmetry for the estimates of the suppressed-to-leading amplitude ratios. We use r = 0.013 ± 0.0023 and r* = 0.019 ± 0.0029, and apply an additional theoretical uncertainty in form of a 15% error range to these.	eps gif
