CO D EX SYMBOL

loopOutput

loopOutput["modelname",LBSM,fieldList]
calculates Wilson Coefficients generated from 1 loop level processes.

DetailsDetails

  • BSM Lagrangian and fieldList are taken as second and third arguments respectively.
  • fieldlist (third argument) : It is a list which has information about the heavy multiplet. The generic structure of the fieldList is : {heavy multiplet name, total number of field components (count each spin 0 , spin 1/2 and spin 1 field), SU(3)C quantum number, SU(2)L quantum number, U(1)Y charge, spin of heavy multiplet, mass of heavy multiplet}
  • Use initializeLoop["modelname",fieldList] to define the matrix representations of respective the symmetries respected by the heavy multiplet in context. Use this "modelname" as the first argument of the 'loopOutput' function.
  • Default dimension six operator basis of 'loopOutput' function is "Warsaw".
  • CoDEx also provides dimension six operators in "SILH" basis. See Examples.
  • Options for loopOutput are:
  • monitorTrueShows an animation while computing
    appearance"Percolate"
    (for Version ≥11.0)    		Appearence of the animation.
    operBasis"Warsaw"Choice of basis of the Dim.-6 operators
    format"List"The output format.
    styleLargeThe fontsize of the output.
    ibpTrueTurns the 'Integration by Parts' option on. Detail available on the loopOutput page.

    • loopOutput also takes all options available to the formatting function 'formPick'

You can see that this takes the model name used by initializeLoop function above (here: "ewrss") to correctly identify the symmetry generators, in addition to the Lagrangian and the list of heavy field definitions. This functionality lets you define multiple models, Lagrangians, and heavy field definitions in the same Notebook and run them without mixing the definitions.

The OptionValue selecting the basis of dimension six operators (operBasis) has its default value set to "Warsaw". We can also choose the "SILH" operator basis. Details of these bases are listed in the guide "CoDExParafernalia".
