“…The SM prediction (A s SL ) SM = (1.9 ± 0.3) • 10 −5 [10], which is often named a s sl or a s fs in the literature, agrees with the direct measurement (A s SL ) exp = −0.0017 ± 0.0092 [50] within the (large) error. However, recent measurements of the like-sign dimuon charge asymmetry A b SL [51], which connects A s SL to its counterpart A d SL of the B 0 d -meson sector [52], imply a deviation of almost 2σ.…”

“…The RS result is shown in Figure 3, where we have sketched the experimental favored values S ψφ = 0.56 ± 0.22 [54] and A s SL = −0.0085 ± 0.0058 [50]. The latter number combines the direct measurement with the results derived from the measurement of A b SL in semileptonic B-decays together with the average A d SL = −0.0047 ± 0.0046 from B-factories.…”

We study the impact of the Randall-Sundrum setup on the width difference ∆Γs and the CPviolating phase φs in theB 0 s -B 0 s system. Our calculations are performed in the general framework of an effective theory, based on operator product expansion. The result can thus be used for many new physics models. We find that the correction to the magnitude of the decay amplitude Γ s 12 is below 4% for a realistic choice of input parameters. The main modification in the ∆Γs/βs-plane is caused by a new CP-violating phase in the mixing amplitude, which allows for a better agreement with the experimental results of CDF and DØ from B 0 s → J/ψφ decays. The best-fit value of the CP asymmetry S ψφ can be reproduced, while simultaneously the theoretical prediction for the semileptonic CP asymmetry A s SL can enter the 1σ range.

“…As far as global fit inputs are concerned, this is the case for the inclusive and exclusive determinations of |V ub | and |V cb |, which involve non-perturbative inputs of different nature. We use the latest HFAG results [10] for each of these determinations and combine inclusive and exclusive determinations following the same scheme as for the combination of lattice quantities. We refer the reader to refs.…”

Predictions of selected flavor observables within the standard model

This letter gathers a selection of Standard Model predictions issued from the metrology of the CKM parameters performed by the CKMfitter group. The selection includes purely leptonic decays of neutral and charged B, D and K mesons. In the light of the expected measurements from the LHCb experiment, a special attention is given to the radiative decay modes of B mesons as well as to the B-meson mixing observables, in particular the semileptonic charge asymmetries a d,s SL which have been recently investigated by the DØ experiment at Tevatron. Constraints arising from rare kaon decays are addressed, in light of both current results and expected performances of future rare kaon experiments. All results have been obtained with the CKMfitter analysis package, featuring the frequentist statistical approach and using Rfit to handle theoretical uncertainties.

“…These toy experiments also reproduce the quoted 95% CL limits, giving some support to this approximate treatment. The Tevatron results were afterwards recomputed using the latest world average f d /f s = 3.71 ± 0.47 [50], for consistency with the LHCb analysis. The results of the three experiments were combined using the CL s method, treating the error on f d /f s and the branching ratio of B + → J/ψ(µ + µ − )K + as systematic errors common to the three experiments.…”

Supersymmetry and dark matter in light of LHC 2010 and XENON100 data

et al. 2011

View full text Add to dashboard Cite

We make frequentist analyses of the CMSSM, NUHM1, VCMSSM and mSUGRA parameter spaces taking into account all the public results of searches for supersymmetry using data from the 2010 LHC run and the Xenon100 direct search for dark matter scattering. The LHC data set includes ATLAS and CMS searches for jets + / ET events (with or without leptons) and for the heavier MSSM Higgs bosons, and the upper limit on BR(Bs → µ + µ − ) including data from LHCb as well as CDF and DØ. The absences of signals in the LHC data favour somewhat heavier mass spectra than in our previous analyses of the CMSSM, NUHM1 and VCMSSM, and somewhat smaller dark matter scattering cross sections, all close to or within the pre-LHC 68% CL ranges, but do not impact significantly the favoured regions of the mSUGRA parameter space. We also discuss the impact of the Xenon100 constraint on spin-independent dark matter scattering, stressing the importance of taking into account the uncertainty in the π-nucleon σ term ΣπN , that affects the spin-independent scattering matrix element, and we make predictions for spin-dependent dark matter scattering. Finally, we discuss briefly the potential impact of the updated predictions for sparticle masses in the CMSSM, NUHM1, VCMSSM and mSUGRA on future e + e − colliders.
