A calculator for confidence intervals

  • Roger Barlow (Contributor)



    A calculator program has been written to give confidence intervals on branching ratios for rare decay modes (or similar quantities) calculated from the number of events observed, the acceptance factor, the background estimate and the associated errors. Results from different experiments (or different channels from the same experiment) can be combined. The calculator is available in http://www.slac.stanford.edu/~barlow/limits.html.

    Title of program: syslimit
    Catalogue Id: ADQN_v1_0

    Nature of problem
    Calculating confidence intervals for a Poisson mean based on observed data, with uncertainties in efficiencies and backgrounds.
