HARD-PHOTON EMISSION IN e+e - REACTIONS

TL;DR: In this paper, the authors reevaluate the hadronic contributions to the muon magnetic anomaly, and to the running of the electromagnetic coupling constant at the Z-boson mass, and find that the reduced electromagnetic coupling strength at M ✓ Z ≥ 2 leads to an increase by 12 ǫ in the central value of the Higgs boson mass obtained by the standard Gfitter fit to electroweak precision data.

TL;DR: In this paper, the authors evaluated the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the Z-boson mass.

TL;DR: The physics of the SLAC and KEK B Factories are described in this paper, with a brief description of the detectors, BaBar and Belle, and data taking related issues.

TL;DR: The phenomenological constraints on extra neutral gauge bosons at present and at future colliders are reviewed in this paper, where special attention is paid to the influence of radiative corrections, systematic errors, and kinematic cuts on the Z′ constraints.

TL;DR: In this article, the authors apply the principles of the $S$-matrix theory to electrodynamics by using an approximation scheme different from that in the strong interactions.

TL;DR: In this article, a theorem was proved which showed the possibility of separating experimentally the contribution of the δ-n pion vertex from the contribution δ n pion node.

TL;DR: In this article, the radiative corrections to lowest order for the reaction e−+e+→μ−+μ+ are calculated, taking into account the contribution from high-energy photons emitted by the electrons.
