“…They have been presented at the ICHEP 2014 conference and are preliminary. Belle [834], BABAR [835] and CLEO-c [836,837] collaborations have previously reported results. The Belle collaboration fully reconstructs the D events from the continuum under the Υ (4S) resonance, achieving a very good q 2 resolution (∆q 2 = 15 MeV 2 ) and low background level, but having a low efficiency.…”

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.

“…The z-expansion formalism has been used by BaBar [1168,1172], BES III [1186] and CLEO-c [1173], [1174]. Their fits use the first three terms of the expansion, and the results for the ratios r 1 ≡ a 1 /a 0 and r 2 ≡ a 2 /a 0 are listed in Tables 273 and 274.…”

“…With the entire CLEO-c data sample, 818 pb −1 , 14,123 and 1374 signal events are reconstructed for the D 0 → K − e + ν and D 0 → π − e + ν channels, and 8467 and 838 for the D + → K 0 e + ν and D + → π 0 e + ν decays, respectively. Another technique without tagging the D meson in a hadronic mode ("untagged" in the following) has been also used by CLEO-c [1174]. In this method, the entire missing energy and momentum in an event are associated with the neutrino four momentum, with the penalty of larger background as compared to the tagged method.…”

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 ...

Lattice Gauge Theory and the Origin of Mass

Most of the mass of everyday objects resides in atomic nuclei; the total of the electrons' mass adds up to less than one part in a thousand. The nuclei are composed of nucleons-protons and neutrons-whose nuclear binding energy, though tremendous on a human scale, is small compared to their rest energy. The nucleons are, in turn, composites of massless gluons and nearly massless quarks. It is the energy of these confined objects, via M = E/c 2 , that is responsible for everyday mass. This article discusses the physics of this mechanism and the role of lattice gauge theory in establishing its connection to quantum chromodynamics.
