Decay rate and lifetime of Z Boson

In summary, the accepted numbers for the decay rate and lifetime of Z-> mu+mu- and Z-> e+e- decays are approximately 3×10-25 seconds and can be computed from the number of Z bosons present. The unit for the decay rate is typically given in inverse seconds. These values can be found on the Particle Data Group website.

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.

FAQ: Decay rate and lifetime of Z Boson

What is the decay rate of a Z boson?

The decay rate of a Z boson is approximately 2.5 x 10^-25 seconds, which means that it can decay and transform into other particles in that amount of time.

How is the decay rate of a Z boson measured?

The decay rate of a Z boson is typically measured using high-energy particle colliders, such as the Large Hadron Collider (LHC) at CERN. By analyzing the data from particle collisions, scientists can determine the decay rate and lifetime of the Z boson.

What factors affect the decay rate of a Z boson?

The decay rate of a Z boson can be affected by several factors, including the Z boson's energy, the mass of the particles it decays into, and the quantum state of the particles involved.

What is the lifetime of a Z boson?

The lifetime of a Z boson is approximately 3 x 10^-25 seconds. This is the average amount of time that a Z boson exists before decaying into other particles.

How does the decay rate of a Z boson compare to other particles?

The decay rate of a Z boson is relatively slow compared to other particles. For example, the decay rate of a pion is about 2.6 x 10^-8 seconds, which is about a billion times faster than a Z boson.
