Decay time of different types of bosons, hadrons and fermions

Click For Summary
SUMMARY

This discussion focuses on the decay times of various bosons, hadrons, and fermions, emphasizing the importance of the Particle Data Group (PDG) as a primary resource for public information on particle lifetimes. The formula for calculating the lifetime of hadron resonances, t_X = \hbar / \Gamma_X, is highlighted, with a specific example provided for the \Delta(1232) resonance, where its width \Gamma_\Delta is approximately 117 MeV. The calculated lifetime of the \Delta(1232) is approximately 1.7 fm/c, demonstrating the practical application of the formula in particle physics.

PREREQUISITES
  • Understanding of particle physics concepts, including bosons, hadrons, and fermions
  • Familiarity with the Particle Data Group (PDG) resources
  • Knowledge of quantum mechanics, specifically the relationship between width and lifetime
  • Basic proficiency in using scientific notation and units in particle physics
NEXT STEPS
  • Research the Particle Data Group (PDG) database for comprehensive particle information
  • Study the implications of decay widths on particle lifetimes in quantum mechanics
  • Explore additional examples of hadron resonances and their decay times
  • Learn about the significance of the \hbar constant in particle physics calculations
USEFUL FOR

Physicists, students of particle physics, and researchers interested in the decay properties of subatomic particles will benefit from this discussion.

I'm interested in knowing where can i find the information on decay time of (possibly every?) different type of bosons, hadrons and fermions, which is available to the public (tiletles of books, articles, ...). Any suggestions or ideas?
 
Physics news on Phys.org
And for some hadron resonances X, in case you can't find their lifetime, t_X, you can use their width, \Gamma_X:
t_X = \frac{\hbar}{\Gamma_X}
-------------
e.g. such is the case of \Delta(1232) from what I saw...
pdgLive (lbl.gov)
with \Gamma_\Delta \approx 117 \text{ MeV} (from pdg)
and \hbar c \approx 197.327 \text{ MeV fm} (just a conversion constant)
you get:
t_\Delta = \frac{\hbar}{\Gamma_X}= \frac{\hbar c}{\Gamma_X ~c}=\frac{197.327}{117} \text{ fm/c} \approx 1.7 \text{ fm/c}
which is the lifetime of the \Delta(1232) at its pole mass (Fig.2 1507.03279.pdf (arxiv.org) ).
