${{\mathit \mu}}/{{\mathit p}}$ MAGNETIC MOMENT RATIO

INSPIRE   PDGID:
S004MPR
This ratio is used to obtain a precise value of the muon mass and to reduce experimental muon Larmor frequency measurements to the muon magnetic moment anomaly. Measurements with an error $>$ $0.00001$ have been omitted. By convention, the minus sign on this ratio is omitted. CODATA values were fitted using their selection of data, plus other data from multiparameter fits.
