33. Theory of the $g$ factor of few-electron ions

Zoltan Harman (Max Planck Institute for Nuclear Physics)

11/06/2019, 16:30

Quantum electrodynamic (QED) effects in strong Coulomb fields have been scrutinized recently in high-precision Penning trap $g$ factor experiments. The uncertainty of the atomic mass of the electron has been largely decreased via ...

28. The ALPHATRAP g-factor experiment

Alexander Egl (Max-Planck-Institut für Kernphysik)

11/06/2019, 17:15

The ALPHATRAP experiment [1] at the Max-Planck-Institut für Kernphysik is a cryogenic Penning-trap setup to perform high-precision $g$-factor measurements on highly charged ions (HCI) up to hydrogenlike $^{208}\textrm{Pb}^{81+}$, to test bound-state quantum electrodynamics (BS-QED) [2]. In the vicinity of the nucleus, the electrons bound in HCI experience the strongest electric and magnetic...

56. Many-body study of g factor of boron-like argon

Daniel E. Maison (Saint Petersburg State University)

11/06/2019, 17:35

Experiments on few-electron ions of heavy atoms are of great importance to test bound-state QED. In particular, the most accurate value of the electron mass (almost by two orders of magnitude more precise than the value from the independent measurements) has been obtained in the study of g factor of highly charged ion. An independent determination of the fine-structure constant α is expected...

76. The muon g-2 and the MuonE project

Fulvio Piccinini (Universita and INFN (IT))

11/06/2019, 17:55

After reviewing the theoretical status and the sources of uncertainties of the muon anomalous magnetic moment, I will present the idea of the experiment proposal MUonE aimed at a new determination of the Hadronic Leading Order contribution to the muon g-2. In particular the theoretical challenges related to the proposal will be discussed.

52. Measurement of muon's g-2 and EDM

Tsutomu Mibe (IPNS/KEK)

11/06/2019, 18:15

Anomalous magnetic moment (g-2) and electric dipole moment (EDM) of muon are sensitive tools to study the existence of physics beyond the standard model of particle physics. The Fermilab g-2 experiment is currently running to measure g-2 of positive muon with the muon beam at the magic momentum 3.1GeV/c in a 14 m-diameter storage ring.
The J-PARC g-2/EDM experiment aims to measure g-2 and EDM...

77. e+e- annihilation into hadrons and muon g-2

Simon Eydelman (Budker Institute of Nuclear Physics (RU))

11/06/2019, 18:40

We discuss precise measurements of exclusive and inclusive cross sections performed at various e+e- colliders in the BaBar, BESIII, CMD-3, KEDR, KLOE and SND experiments. Results of these measurements are used for the calculation of hadronic vacuum polarization - an important ingredient of the theoretical prediction for the muon $g-2$ and running fine structure constant in the Standard Model.
