SUMMARY:Theory group seminar on "Testing the Standard Model with a Single
  Electron: A new g-factor measurement and limit on the dark photon"\, SP
 EAKER: Dr Xing Fan (Northwestern University).
TZID:Europe/London
UID:20230428-8a1785d88727a18401873e05347f5b12@warwick.ac.uk

DESCRIPTION:ABSTRACT: A single isolated electron in a Penning trap yields
  a new measurement of the electron magnetic moment g/2 = 1.001 159 652 1
 80 59 (13). A comparison of the measured g-factor and the predicted g-fa
 ctor using an independent measurement of the fine structure constant pro
 vides the most stringent test of the Standard Model. The newly construct
 ed system used for this measurement which resulted in increased stabilit
 y and a better understanding of systematic errors\, along with efforts t
 owards a further improved measurement using new techniques\, will be dis
 cussed. A new limit on dark photon dark matter at 0.6 meV is also obtain
 ed using the same system. The single trapped electron is used as a backg
 round-free detector at 0.6 meV. The search demonstrates the sensitivity 
 of the single electron to the dark photon in the 0.1–1 meV range.
