Search for invisible decays of a dark photon produced in e+e- collisions at BaBar

J. P. Lees, +234 more
TL;DR: 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.

Illuminating dark photons with high-energy colliders

TL;DR: In this paper, the authors show that the 14 TeV LHC and a 100 TeV proton-proton collider provide powerful probes of both exotic Higgs decay channels.

New Exclusion Limits on Dark Gauge Forces from Proton Bremsstrahlung in Beam-Dump Data

TL;DR: In this article, the authors re-analyze published proton beam dump data taken at the U70 accelerator at IHEP Serpukhov with the ν-calorimeter I experiment in 1989 to set mass-coupling limits for dark gauge forces.

Search for the dark photon in π0 decays

J. R. Batley, +120 more
- 18 Mar 2016 - 
TL;DR: In this paper, a sample of 1.69 × 10 7 fully reconstructed π 0 → γ e + e − decay candidates collected by the NA48/2 experiment at CERN in 2003-2004 is analyzed to search for the dark photon (A ′ ) production in the π − 0 → − γ A ′ decay followed by the prompt A − → e + − decay.

Review of Particle Physics: Particle data group

Kaoru Hagiwara, +142 more
- 20 Jul 2012 - 
TL;DR: The Particle Data Group's biennial review as mentioned in this paper summarizes much of particle physics, using data from previous editions, plus 2658 new measurements from 644 papers, and lists, evaluates, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons.

Asymptotic formulae for likelihood-based tests of new physics

TL;DR: In this paper, the authors describe likelihood-based statistical tests for use in high energy physics for the discovery of new phenomena and for construction of confidence intervals on model parameters, focusing on the properties of the test procedures that allow one to account for systematic uncertainties.

Final report of the E821 muon anomalous magnetic moment measurement at BNL

TL;DR: In this article, the authors presented the final report from a series of precision measurements of the muon anomalous magnetic moment, a(mu)=(g-2)/2.54 ppm, which represents a 14-fold improvement compared to previous measurements at CERN.

Two U(1)'s and Epsilon Charge Shifts

TL;DR: If new particles are gauged by a new U(1) then their electromagnetic charges may be shifted by a calculable amount as mentioned in this paper, which is the case in the case of the current article.
