The LHCb experiment at CERN's Large Hadron Collider will soon allow us to enter a new era in the exploration of B s decays. A particularly promising channel for the search of ''new physics'' is B 0 s ! þ À . The systematic key uncertainty affecting the measurement of this-and in fact all B s -decay branching ratios-is the ratio of fragmentation functions f d =f s . As the currently available methods for determining f d =f s are not sufficient to meet the high precision at LHCb, we propose a new strategy using " B 0 s ! D þ s À and " B 0 d ! D þ K À . It allows us to obtain a lower experimental bound on BRðB 0 s ! þ À Þ which offers a powerful probe for new physics. In order to go beyond this bound and to determine f d =f s with a theoretical precision matching the experimental one it is sufficient to know the SUð3Þ-breaking correction to a form-factor ratio from nonperturbative methods at the level of 20%. Thanks to our strategy, we can detect new physics in B 0 s ! þ À at LHCb with 5 for a branching ratio as small as twice the standard model value, which represents an improvement of the new-physics reach by about a factor of 2 with respect to the current LHCb expectation.

“…The LEP experiments have measured [30,31] and [32,33] 6 from partially reconstructed final states including a lepton, f baryon from protons identified in b events [35], and the production rate of charged b hadrons [36]. Ratios of b-hadron fractions have been measured at CDF using lepton+charm final states [37][38][39] 7 , double semileptonic decays with K * µµ and φµµ final states [40], and fully reconstructed B 0 s → J/ψ φ decays [41]. Measurements of the production of other heavy flavour baryons at the Tevatron are included in the determination of f baryon [42][43][44] 8 using the constraint…”

This article reports world averages of measurements of b-hadron, c-hadron, and τlepton properties obtained by the Heavy Flavor Averaging Group (HFAG) using results available through summer 2014. For the averaging, common input parameters used in the various analyses are adjusted (rescaled) to common values, and known correlations are taken into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, CP violation parameters, parameters of semileptonic decays and CKM matrix elements.

“…207 shows all determinations of the CKM matrix elements |V cd | and |V cs |. As can be seen, the most precise direct determinations of these CKM 42 We use the following values (taken from PDG 2014 edition [327]) for external parameters entering Eq. (266): m τ = (1.77686 ± 0.00012) GeV/c 2 , m Ds = (1.96830 ± 0.00010) GeV/c 2 and τ Ds = (500 ± 7) × 10 −15 s. 43 In the case of BaBar we use the covariance matrix from the errata of Ref.…”

This paper reports world averages of measurements of b-hadron, c-hadron, and τ -lepton properties obtained by the Heavy Flavour Averaging Group using results available before April 2021. In rare cases, significant results obtained several months later are also used. For the averaging, common input parameters used in the various analyses are adjusted (rescaled) to common values, and known correlations are taken into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, CP violation parameters, parameters of semileptonic decays, and Cabibbo-Kobayashi-Maskawa matrix elements.

[35]. The proportions of the various production channels for non-strange B mesons have also been measured [22]. 4.3 b-hadron production fractions at high energy At high energy, all species of weakly decaying b hadrons may be produced, either directly or in strong and electromagnetic decays of excited b hadrons. Before 2010, it was assumed that the fractions of different species in unbiased samples of high-p T b-hadron jets where independent of whether they originated from Z decays, pp collisions at the Tevatron, or pp collisions at the LHC. This hypothesis was plausible under the condition Q 2 Λ 2 QCD , namely, that the square of the momentum transfer to the produced b quarks is large compared with the square of the hadronization energy scale. This hypothesis is correct in the limit p T → ∞, in which the production mechanism of a b hadron is completely described by the fragmentation of the b quark. For finite p T , however, there are interference effects of the production mechanism of the b quark and its hadronization. While formally suppressed by inverse powers of p T , these effects may be sizable, especially when the fragmentation probabilities are small as, e.g., in the case of b baryons. In fact, the available data show that the fractions depend on the kinematics of the produced b hadron. Both CDF and LHCb reported a p T dependence of the fractions, with the fraction of Λ 0 b baryons observed at low p T being enhanced with respect to that seen at LEP at higher p T . In our previous publication [1], we presented two sets of averages, one including only measurements performed at LEP, and another including only measurements performed ...
