The meter is the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second. At Q2 = 0. At Q2 m2W the value is 1/128.

Absolute lab measurements of GN have been made only on scales of about 1 cm to 1 m. See the discussion in Sec. 10, Electroweak model and constraints on new physics. The corresponding sin2 for the effective angle is 0.23146(12).

NOTES

In this Summary Table:

When a quantity has \(S = . . .)" to its right, the error on the quantity has been

enlarged by the \sale fator" S, dened as S =

2/(N 1), where N is the

number of measurements used in alulating the quantity. We do this when S > 1,whih often indiates that the measurements are inonsistent. When S > 1.25,we also show in the Partile Listings an ideogram of the measurements. For more

about S, see the Introdution.

A deay momentum p is given for eah deay mode. For a 2-body deay, p is the

momentum of eah deay produt in the rest frame of the deaying partile. For a

3-or-more-body deay, p is the largest momentum any of the produts an have in

this frame.

[a Theoretial value. A mass as large as a few MeV may not be preluded.

[b indiates eah type of lepton (e, , and ), not sum over them.

[ This represents the width for the deay of the W boson into a harged

partile with momentum below detetability, p< 200 MeV.

[d The Z -boson mass listed here orresponds to a Breit-Wigner resonane

parameter. It lies approximately 34 MeV above the real part of the posi-

tion of the pole (in the energy-squared plane) in the Z -boson propagator.

[e This partial width takes into a

ount Z deays into and any otherpossible undeteted modes.

[f This ratio has not been orreted for the mass.

[h The value is for the sum of the harge states or partile/antipartile

states indiated.

[i This value is updated using the produt of (i) the Z bbfration from this listing and (ii) the b-hadron fration in an

unbiased sample of weakly deaying b-hadrons produed in Z -

deays provided by the Heavy Flavor Averaging Group (HFAG,

http://www.sla.stanford.edu/xorg/hfag/os/PDG 2009/#FRACZ).

[j See the Z Partile Listings in the Full Review of Partile Physis for the

energy range used in this measurement.

[k For m = (60 5) GeV.

NOTES

In this Summary Table:

When a quantity has \(S = . . .)" to its right, the error on the quantity has been

enlarged by the \sale fator" S, dened as S =

2/(N 1), where N is the

number of measurements used in alulating the quantity. We do this when S > 1,whih often indiates that the measurements are inonsistent. When S > 1.25,we also show in the Partile Listings an ideogram of the measurements. For more

about S, see the Introdution.

A deay momentum p is given for eah deay mode. For a 2-body deay, p is the

momentum of eah deay produt in the rest frame of the deaying partile. For a

3-or-more-body deay, p is the largest momentum any of the produts an have in

this frame.

[a This is the best limit for the mode e

. The best limit for \eletrondisappearane" is 6.4 1024 yr.

[b See the \Note on Muon Deay Parameters" in the Partile Listings inthe Full Review of Partile Physis for denitions and details.

[ P is the longitudinal polarization of the muon from pion deay. In

standard VA theory, P = 1 and = = 3/4.

[d This only inludes events with the energy> 10 MeV. Sine the ee
