Calculating Cross Sections in Supersymmetry: A Comprehensive Guide

Click For Summary
SUMMARY

This discussion focuses on calculating cross sections in supersymmetry, highlighting essential resources for mastering the topic. Key references include "Theory and Phenomenology of Sparticles" by M. Drees, R.M. Godbole, and P. Roy, particularly Chapter 6, which covers relevant calculations and vertices. The discussion also emphasizes the importance of context, such as using velocity expansions for WIMPs and neutralinos to derive partial wave amplitudes and cross sections. The provided arXiv paper by M. Drees and M.M. Nojiri serves as an additional resource for understanding these calculations.

PREREQUISITES
  • Familiarity with quantum field theory concepts, particularly matrix element amplitudes.
  • Understanding of supersymmetry and its associated processes.
  • Knowledge of calculating cross sections in particle physics.
  • Experience with WIMPs and neutralinos in the context of supersymmetric models.
NEXT STEPS
  • Study "Theory and Phenomenology of Sparticles" by M. Drees, R.M. Godbole, and P. Roy for detailed calculations.
  • Read the arXiv paper by M. Drees and M.M. Nojiri on WIMPs and neutralinos.
  • Explore advanced techniques for calculating partial wave amplitudes in supersymmetry.
  • Investigate the role of helicity states in supersymmetric cross section calculations.
USEFUL FOR

This discussion is beneficial for particle physicists, researchers in supersymmetry, and students seeking to deepen their understanding of cross section calculations in the context of supersymmetric processes.

Hi there,

In particle physics there is famous books as Peskin's book " To Quantum Field Theory (Frontiers in Physics) " to learn matrix element amplitude and cross section calculations, like ee -> mu mu.

Are there similar references for supersymmetry to learn how to calculate the cross section of prototype supersymetric processes ?

Bests.

The ideas don't change much... you may just have more diagrams to add up and different vertices...
One book which has some calculations is : M.Drees, R.M. Godbole and P.Roy - Theory and Phenomenology of Sparticles (eg. ch.6 and I think it has the vertices in appendices A,B).

Also it depends on the context, eg for WIMPs neutralinos you can use the expansion in velocities and work with helicity states to deduce the partial wave amplitudes and cross sections from them.
