This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2658 new measurements from 644 papers, we list, evaluate, and average measured properties of gauge
Review of Particle Physics, 2016-2017
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 papers, we list, evaluate, and average measured properties of
Evidence for an excess of B→D*τ(-)ν(τ) decays.
Improved measurements of the ratios R(D(*))=B(B[over ¯]→D(*)τ(-)ν[ over ¯](τ))/B( B[over¯]→B(*)ℓ(ℑ)(-)ν [over ¯](ℒ)), where ℓ is either e or μ, are reported, which are sensitive to new physics contributions in the form of a charged Higgs boson.
Test of lepton universality using b+ → K+ℓ+ℓ- decays.
The value of the ratio of branching fractions for the dilepton invariant mass squared range 1 < q(2) < 6 GeV(2)/c(4) is measured to be 0.745(-0.074)(+0.090)(stat) ± 0.036(syst).
Search for a dark photon in e(+)e(-) collisions at BABAR.
A search for a dark photon in the reaction e+e-→γA^{'}, A^{'}→e^{+}e-, μ+}μ- using 514  fb^{-1} of data collected with the BABAR detector shows no statistically significant deviations from the standard model predictions.
Search for Invisible Decays of a Dark Photon Produced in e^{+}e^{-} Collisions at BaBar.
Limits on the coupling strength of A^{'} to e^{+}e^{-} in the mass range m_{A^{'}}≤8  GeV are set, which exclude the values of the A^' coupling suggested by thedark-photon interpretation of the muon (g-2)_{μ} anomaly, as well as a broad range of parameters for the dark-sector models.
Angular analysis of the B0 → K*0μ+μ− decay using 3 fb−1 of integrated luminosity
A bstractAn angular analysis of the B0 → K*0(→ K+π−)μ+μ− decay is presented. The dataset corresponds to an integrated luminosity of 3.0 fb−1 of pp collision data collected at the LHCb experiment. The
Observation of J/ψp Resonances Consistent with Pentaquark States in Λ_{b}^{0}→J/ψK^{-}p Decays.
To obtain a satisfactory fit of the structures seen in the J/ψp mass spectrum, it is necessary to include two Breit-Wigner amplitudes that each describe a resonant state.
Differential branching fractions and isospin asymmetries of B → K(*)μ+μ− decays
A bstractThe isospin asymmetries of B → Kμ+μ− and B → K*μ+μ− decays and the partial branching fractions of the B0 → K0μ+μ−, B+ → K+μ+μ− and B+ → K*+μ+μ− decays are measured as functions of the dimuon
Measurement of form-factor-independent observables in the decay B0→K(*0)μ(+)μ(-).
A measurement of form-factor-independent angular observables in the decay B(0)→K*(892)(0)μ(+)μ(-) is presented, based on a data sample collected by the LHCb experiment in pp collisions at a center-of-mass energy of 7 TeV.
