Methods of Finding Asymmetry

• Asymmetry estimates.
  • This link is the top thread for the discussion of asymmetry measurements in TWIST analysis.
  • The three methods are:
    • Difference over sum of integrating upstream and downstream counts. (PmuXi ~ 6*Asym).
    • Fit for slope and intercept of cos(theta), then PmuXi ~ 3.*m/b
    • Fit for normalized endpoint ratio (r) in bins of cos(theta), then PmuXiDelta/rho ~ 1-r(1)
