f_B and f_Bs with maximally twisted Wilson fermions
ETM Collaboration, B. Blossier, P. Dimopoulos +13
We present a lattice QCD calculation of the heavy-light decay constants f_B and f_Bs performed with Nf=2 maximally twisted Wilson fermions, at four values of the lattice spacing. T…
Vector and scalar form factors for K- and D-meson semileptonic decays from twisted mass fermions with Nf = 2
S. Di Vita, B. Haas, F. Mescia +3
We present lattice results for the form factors relevant in the K -> pion and D -> pion semileptonic decays, obtained from simulations with two flavors of dynamical twisted-mass fe…
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…
FCNC Processes in the LHT Model: a 2009 Look
Cecilia Tarantino
We present a summary of our recent analysis update of flavour changing neutral current (FCNC) processes in the Littlest Higgs model with T-parity (LHT). The essential novelties of…
A proposal for B-physics on current lattices
ETM collaboration, B. Blossier, P. Dimopoulos +11
A method to extract B-physics parameters (b-quark mass and fB, fBs decay constants) from currently available lattice data is presented and tested. The approach is based on the idea…
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…
