Standard Model updates and new physics analysis with the Unitarity Triangle fit
Adrian Bevan, Marcella Bona, Marco Ciuchini +12
We present here the update of the Unitarity Triangle (UT) analysis performed by the UTfit Collaboration within the Standard Model (SM) and beyond. Continuously updated flavour resu…
The UTfit Collaboration Average of meson mixing data: Winter 2014
UTfit Collaboration, A. J. Bevan, M. Bona +13
We update the analysis of meson mixing including the latest experimental results as of January 2014. We derive constraints on the parameters , and tha…
The UTfit Collaboration Average of D meson mixing data: Spring 2012
UTfit Collaboration, A. J. Bevan, M. Bona +13
We derive constraints on the parameters , and that describe meson mixing using all available data, allowing for CP violation. We also provide posterio…
Status of the Unitarity Triangle Analysis
M. Bona, M. Ciuchini, E. Franco +10
We present an update of the Unitarity Triangle (UT) analysis, within the Standard Model (SM) and beyond. Within the SM the main novelties are the inclusion in epsilon_K of the cont…
An Improved Standard Model Prediction Of BR(B -> tau nu) And Its Implications For New Physics
UTfit Collaboration, M. Bona, M. Ciuchini +11
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 o…
Update of the Unitarity Triangle Analysis
Cecilia Tarantino
We present the update of the Unitarity Triangle (UT) analysis within the Standard Model (SM) and beyond. Within the SM, combining the direct measurements on sides and angles, the U…
First Evidence of New Physics in b <--> s Transitions
The UTfit Collaboration, M. Bona, M. Ciuchini +10
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…
Model-independent constraints on Delta F=2 operators and the scale of New Physics
UTfit Collaboration, M. Bona, M. Ciuchini +11
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.…
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)
UTfit Collaboration, M. Bona, M. Ciuchini +10
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 Tria…
The UTfit Collaboration Report on the Status of the Unitarity Triangle beyond the Standard Model I. Model-independent Analysis and Minimal Flavour Violation
UTfit Collaboration, M. Bona, M. Ciuchini +10
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…
The 2004 UTfit Collaboration Report on the Status of the Unitarity Triangle in the Standard Model
UTfit Collaboration, M. Bona, M. Ciuchini +9
Using the latest determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constrai…
