An Improved Standard Model Prediction Of BR(B -> tau nu) And Its Implications For New Physics (2009)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

The recently measured B -> tau nu branching ratio allows to test the Standard Model by probing virtual effects of new heavy particles, such as a charged Higgs boson. The accuracy of the test is...

First Evidence of New Physics in b s Transitions (2008)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

We combine all the available experimental information on Bs mixing, including the very recent tagged analyses of Bs to J/Psi phi by the CDF and D0 collaborations. We find that the phase of the Bs...

Model-independent constraints on Delta F=2 operators and the scale of New Physics (2007)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

We update the constraints on new-physics contributions to Delta F=2 processes from the generalized unitarity triangle analysis, including the most recent experimental developments. Based on these...

Improved Determination of the CKM Angle alpha from B to pi pi decays (2007)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

Motivated by a recent paper that compares the results of the analysis of the CKM angle alpha in the frequentist and in the Bayesian approaches, we have reconsidered the information on the hadronic...

The Unitarity Triangle Fit in the Standard Model and Hadronic Parameters from Lattice QCD: A Reappraisal after the Measurements of Delta m_s and BR(B to tau nu) (2006)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

The recent measurements of the B_s meson mixing amplitude by CDF and of the leptonic branching fraction BR(B to tau nu) by Belle call for an upgraded analysis of the Unitarity Triangle in the...

Constraints on new physics from the quark mixing unitarity triangle (2006)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

The status of the Unitarity Triangle beyond the Standard Model including the most recent results on Delta m_s, on dilepton asymmetries and on width differences is presented. Even allowing for general...

The UTfit Collaboration Report on the Status of the Unitarity Triangle beyond the Standard Model I. Model-independent Analysis and Minimal Flavour Violation (2005)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

Starting from a (new physics independent) tree level determination of rhobar and etabar, we perform the Unitarity Triangle analysis in general extensions of the Standard Model with arbitrary new...

The 2004 UTfit Collaboration Report on the Status of the Unitarity Triangle in the Standard Model (2005)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

Using the latest determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from the...

CKM-Triangle analysis: Updates and Novelties for Summer 2004 (2004)

Bona, UTfit Collaboration: M., Ciuchini, M., Franco, E., Lubicz, V., Martinelli, G., Parodi, F., ...

Using the most recent determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from...
