Illustrative Key to the Particle Listings

Name of particle. "Old" name used before 1986 renaming scheme also given if different. See the section "Naming Scheme for Hadrons" for details.

$a_0(1200)$

OMITTED FROM SUMMARY TABLE

Evidence not compelling, may be a kinematic effect.

$I^G(JPC) = 1^{-}(0^{++})$

Particle quantum numbers (where known).

Indicates particle omitted from Particle Physics Summary Table, implying particle's existence is not confirmed.

Quantity tabulated below.

Top line gives our best value (and error) of quantity tabulated here, based on weighted average of measurements used. Could also be from fit, best limit, estimate, or other evaluation. See next page for details.

Footnote number linking measurement to text of footnote.

Number of events above background.

Measured value used in averages, fits, limits, etc.

Error in measured value (often statistical only; followed by systematic if separately known; the two are combined in quadrature for averaging and fitting.)

Measured value *not used* in averages, fits, limits, etc. See the Introductory Text for explanations.

Arrow points to weighted average.

Shaded pattern extends ±1σ (scaled by "scale factor" S) from weighted average.

Value and error for each experiment.

Indicator of Procedure Used to Obtain Our Result

OUR AVERAGE From a weighted average of selected data.

OUR FIT From a constrained or overdetermined multiparameter fit of selected data.

OUR EVALUATION Not from a direct measurement, but evaluated from measurements of other quantities.

OUR ESTIMATE Based on the observed range of the data. Not from a formal statistical procedure.

OUR LIMIT For special cases where the limit is evaluated by us from measured ratios or other data. Not from a direct measurement.
