“…Oscillations have been observed in the K 0 À " [2], and B 0 s À " B 0 s [3] systems, all with rates in agreement with SM expectations. Evidence of D 0 À " D 0 oscillations has been reported by three experiments using different D 0 decay channels [4][5][6][7][8]. Only the combination of these measurements provides confirmation of D 0 À " D 0 oscillations, also referred to as charm mixing, with more than 5 significance [9].…”

“…192 and 193, respectively. The D 0 → K + π − measurements used are from Belle [1066,1067], BaBar [1049], CDF [1068], and more recently LHCb [1051,1069]; earlier measurements have much less precision and are not used. The observables from D 0 → K 0 S π + π − decays are measured in two ways: assuming CP conservation (D 0 andD 0 decays combined), and allowing for CP violation (D 0 andD 0 decays fitted separately).…”

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.

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 ...

“…44) This implies that the weak eigenstates are not exact CP eigenstates, and that there is a small fraction of indirect CP violation in this system. system has only recently been observed by the BaBar [36] and CDF [37] collaborations. This is a very small effect, and its observation relies on the highly accurate flavour tagging of the initial state which is achievable from knowledge of the D 0 meson production process.…”
