New Measurement of the Electron Magnetic Moment and the Fine Structure Constant
read the original abstract
A measurement using a one-electron quantum cyclotron gives the electron magnetic moment in Bohr magnetons, g/2 = 1.001 159 652 180 73 (28) [0.28 ppt], with an uncertainty 2.7 and 15 times smaller than for previous measurements in 2006 and 1987. The electron is used as a magnetometer to allow lineshape statistics to accumulate, and its spontaneous emission rate determines the correction for its interaction with a cylindrical trap cavity. The new measurement and QED theory determine the fine structure constant, with alpha^{-1} = 137.035 999 084 (51) [0.37 ppb], and an uncertainty 20 times smaller than for any independent determination of alpha.

LFV decays in a 3-4-1 model with minimal inverse seesaw neutrinos
In a 3-4-1 model with minimal inverse seesaw, strong correlations are predicted between (g-2) anomalies and LFV decay rates, with the tau to muon gamma decay bound limiting the muon anomaly deviation to 10^{-9}.

Doubly charged Higgs production within the Higgs triplet model at future electron-positron colliders
CLIC offers superior discovery potential for doubly charged Higgs bosons in the Higgs triplet model compared to HL-LHC, reaching masses up to 1.2 TeV in gauge-like scenarios and high significance in Yukawa-like region...
