Decay rate and lifetime of Z Boson

Click For Summary
SUMMARY

The Z boson has an accepted half-life of approximately 3×10-25 seconds. The decay rate can be computed if a significant number of Z bosons are present, but it is important to note that lifetime is a fundamental property of the particle itself, not dependent on specific decay channels such as Z → μ⁺μ⁻ or Z → e⁺e⁻. For detailed values and references, the Particle Data Group (PDG) is the standard source for particle data.

PREREQUISITES
  • Understanding of particle physics concepts
  • Familiarity with decay rates and lifetimes of subatomic particles
  • Knowledge of the Z boson and its decay channels
  • Access to the Particle Data Group (PDG) database
NEXT STEPS
  • Research the decay channels of the Z boson, specifically Z → μ⁺μ⁻ and Z → e⁺e⁻
  • Explore the Particle Data Group (PDG) database for comprehensive particle data
  • Study the implications of decay rates in particle physics experiments
  • Learn about the role of half-life in understanding particle stability
USEFUL FOR

Particle physicists, researchers in high-energy physics, and students studying subatomic particles will benefit from this discussion.

What are the accepted numbers for the decay rate and lifetime of Z-> mu+mu- and Z-> e+e- decays? also what is the unit for the decay rate? thank you!

Welcome to PF;
The Z boson has an accepted half-life about 3×10-25 s

If you happen to have a lot of them, then the decay rate can be computed from that.
 
Lifetime is a property of a particle, not a property of a decay channel.

See the values given by the http://pdglive.lbl.gov/Rsummary-wait.brl?fsizein=1&nodein=S044 , it is the usual reference for any particle data.
