The Michel parameters, usually denoted by and, are four parameters used in describing the phase space distribution of leptonic decays of charged leptons, . They are named after the physicist Louis Michel. Sometimes instead of, the product is quoted. Within the Standard Model of electroweak interactions, these parameters are expected to be
Precise measurements of energy and angular distributions of the daughter leptons in decays of polarized muons and tau leptons are so far in good agreement with these predictions of the Standard Model.

Famous quotes containing the word parameters:
“Men have defined the parameters of every subject. All feminist arguments, however radical in intent or consequence, are with or against assertions or premises implicit in the male system, which is made credible or authentic by the power of men to name.”
—Andrea Dworkin (b. 1946)
