! main07.cmnd. ! This file contains commands to be read in for a Pythia8 run. ! Lines not beginning with a letter or digit are comments. ! 1) Settings used in the main program. Main:numberOfEvents = 1000 ! number of events to generate Main:timesAllowErrors = 5 ! allow a few failures before quitting ! 2) Settings related to output in init(), next() and stat(). Init:showChangedSettings = on ! list changed settings Init:showChangedParticleData = on ! list changed particle data Next:numberCount = 100 ! print message every n events Next:numberShowInfo = 1 ! print event information n times Next:numberShowProcess = 1 ! print process record n times Next:numberShowEvent = 1 ! print event record n times ! 3) Beam parameter settings. Incoming beams do not radiate. Beams:idA = -11 ! ficititious incoming e+ Beams:idB = 11 ! ficititious incoming e- PDF:lepton = off ! no radiation off ficititious e+e- Beams:eCM = 500. ! CM energy of collision ! 4) Set up properties of the GeneralResonance and its decay channels. ! id:all = name antiName spinType chargeType colType m0 mWidth mMin mMax tau0 999999:all = GeneralResonance void 1 0 0 500. 1. 0. 0. 0. ! id:addChannel = onMode bRatio meMode product1 product2 ... ! Note: sum of branching ratios automatically rescaled to 1. ! Current channels illustrative only; insert your own decay list. 999999:addChannel = 1 0.2 101 1 -1 ! -> d dbar 999999:addChannel = 1 0.2 101 6 -6 ! -> t tbar 999999:addChannel = 1 0.2 101 15 -15 ! -> tau- tau+ 999999:addChannel = 1 0.2 101 24 -24 ! -> W+ W- 999999:addChannel = 1 0.2 101 25 25 ! -> h0 h0 ! 5) Tell that also long-lived should decay. 13:mayDecay = true ! mu+- 211:mayDecay = true ! pi+- 321:mayDecay = true !
