Impact of ∆mBs on the determination of the unitary triangle and bounds on physics beyond the Standard Model
نویسنده
چکیده
In this note we study the impact of the recent ∆mBs results, obtained at the Tevatron Run II by the CDF and DØ collaborations, on the analysis of the Unitary Triangle (UT) in the Standard Model (SM) and in particular show how these measurements futher constrain the compatibility between the experimental value of sin 2β = (0.623, 0.751) at 95% C.L. and the value obtained by the fit of the UT parameters considering just CP conserving experimental observables: sin 2β = (0.751, 0.841) at 95% C.L. We also obtain new bounds on certain classes of processes beyond the SM.

The g-factor of the charged leptons has always been considered by many physicists, both experimentaly as well as theoretically. In fact the electron and muon g-factor play the main role in testing the QED as well as the standard model. Meanwhile, there is a discrepancy between the standard model prediction of the muon anomalies magnetic moment and its experimental determination as large as (25...
متن کاملSome bounds on unitary duals of classical groups - non-archimeden case
We first give bounds for domains where the unitarizabile subquotients can show up in the parabolically induced representations of classical $p$-adic groups. Roughly, they can show up only if the central character of the inducing irreducible cuspidal representation is dominated by the square root of the modular character of the minimal parabolic subgroup. For unitarizable subquotients...
متن کاملSome Prospects for the Determination of the Unitarity Triangle before the LHC Era*
Anticipating improved determinations of mt, |Vcb|, |Vub/Vcb|, BK and FB √ BB in the next five years we make an excursion into the future in order to find a possible picture of the unitarity triangle, of quark mixing and of CP violation around the year 2000. We then analyse what impact on this picture will result from the measurements of the four possibly cleanest quantities: BR(K → πνν̄), xd/xs,...
متن کاملImpacts of Premium Bounds on the Operation of Put Option and Day-ahead Electricity Markets
In this paper, the impacts of premium bounds of put option contracts on the operation of put option and day-ahead electricity markets are studied. To this end, first a comprehensive equilibrium model for a joint put option and day-ahead markets is presented. Interaction between put option and day-ahead markets, uncertainty in fuel price, impact of premium bounds, and elasticity of con...
متن کاملSelection of LHCb results from Run I
At the eve of the second LHC data taking run, some of the most recent results obtained by the LHCb collaboration with Run I data are reviewed. Improved measurements on CP violation, unitary triangle and mixing parameters are shown. Recent progress on physics in the forward region is illustrated by examples picked up in the electroweak physics and beyond Standard Model searches.
