Current status of the Standard Model CKM fit and constraints on New Physics
J. Charles, O. Deschamps, S. Descotes-Genon +12
This letter summarises the status of the global fit of the CKM parameters within the Standard Model performed by the CKMfitter group. Special attention is paid to the inputs for th…
Dispersive evaluation of the second-class amplitude in the standard model
S. Descotes-Genon, E. Kou, B. Moussallam
We reevaluate the two form factors relevant for the second-class decay mode, making systematic use of analyticity, unitarity, combined with updated inputs to the NLO chira…
Implications of LHCb measurements and future prospects
LHCb collaboration, A. Bharucha, I. I. Bigi +763
During 2011 the LHCb experiment at CERN collected 1.0 fb-1 of sqrt{s} = 7 TeV pp collisions. Due to the large heavy quark production cross-sections, these data provide unprecedente…
New Physics in B-Bbar mixing in the light of recent LHCb data
A. Lenz, U. Nierste, J. Charles +5
We perform model-independent statistical analyses of three scenarios accommodating New Physics (NP) in Delta F=2 flavour-changing neutral current amplitudes. In a scenario in which…
Exploring New Physics in C_7-C_7'
S. Descotes-Genon, D. Ghosh, J. Matias +1
We discuss the model dependence in the determination of the Wilson coefficient C_7 that governs the radiative electromagnetic decays of B mesons in the Standard Model, by consideri…
A note on renormalon models for the determination of alpha_s(M_tau)
S. Descotes-Genon, B. Malaescu
The tau hadronic width provides a determination of the strong coupling constant alpha_s at low energies, since it can be related to a weighted integral of the Adler function in the…
