SUMMARY

The discussion focuses on modeling a four-body decay for a PDF, specifically addressing the "particle mass dependency" in the equations. The user references the Particle Data Group's 2009 review, particularly equations 38.16, 38.20a, and 38.20b, which outline the mass dependency for two and three-body decays. The user seeks assistance from someone with a theoretical background to navigate the complexities of a four-body integral. A peer offers to share relevant research papers privately to aid in the user's understanding.

PREREQUISITES
  • Understanding of particle decay processes
  • Familiarity with kinematic equations in particle physics

Research Problem -- 4-body Decay

Hello,
I am trying to model a four body decay for a PDF I am creating, but I am having some trouble coming up with the "particle mass dependency" part of the equation - see http://pdg.lbl.gov/2009/reviews/rpp2009-rev-kinematics.pdf page 3 under 'two body decays' for an idea of what I am talking about - equation 38.16. If you look on page four, equation (38.20a) and ((38.20b)) this gives the mass dependency part of the equation (multiply them together) for three body decays, and I was hoping someone with a bit of a theoretical background could help me work through a four body integral.

Thanks!

Craig

I actually found such paper yesterday, I can send it to you if you send me your personal e-mail as a personal message to me. Dont post it here in the public forum!
