SUMMARY

The branching fraction of the B0 -> K* mu mu decay is approximately 8 x 10^-7, as referenced in the Particle Data Group's 2008 tables. This decay process is complicated by the presence of intermediate states such as J/Psi and Psi(2S), necessitating a subtraction mechanism for accurate measurement. Consequently, a single well-defined value for the branching fraction does not exist, and the provided figure serves as a rough estimate. For further details, consult the Particle Data Group's website.

PREREQUISITES
  • Understanding of particle physics and decay processes
  • Familiarity with branching fractions in particle decays
  • Knowledge of intermediate resonances like J/Psi and Psi(2S)
  • Access to the Particle Data Group (PDG) resources
NEXT STEPS
  • Research the Particle Data Group's latest tables for updated decay information
  • Study the mechanisms of subtraction in particle decay measurements
  • Explore the significance of intermediate states in B meson decays
  • Learn about the experimental methods used to measure branching fractions
USEFUL FOR

This discussion is beneficial for undergraduate students in particle physics, researchers studying B meson decays, and anyone interested in the complexities of measuring branching fractions in high-energy physics.

hi can anyone tell me what the branching fraction of B0 -> K* mu mu decay is and/or tell me a webpage i can find info on this decay which is accessible to ppl that doesn't have a huge knowledge in this field (i am an undergraduate)

thanks

It's not simple, as mu+mu- includes the J/Psi and the Psi(2S), so some mechanism of subtraction is required. That means there isn't a single number that is well-defined.
