! This file contains commands to be read in for a Pythia8 run. ! Lines not beginning with a letter or digit are comments. ! 1) Settings parameters used in a main program !Main:numberOfEvents = 10000 ! number of events to generate Main:numberOfEvents = 10 ! number of events to generate Main:timesAllowErrors = 30 ! max number of allowed errors ! 2) Settings related to output in init(), next() and stat(). Init:showChangedSettings = on ! list changed settings Init:showAllSettings = off ! list all settings Init:showChangedParticleData = on ! list changed particle data Init:showAllParticleData = off ! list all particle data Next:numberCount = 1000 ! print message every n events Next:numberShowLHA = 1 ! print LHA information n times Next:numberShowInfo = 1 ! print event information n times Next:numberShowProcess = 1 ! print process record n times Next:numberShowEvent = 1 ! print event record n times Stat:showPartonLevel = on ! additional statistics on MPI ! 3) LHC beams parameter settings. Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212, e = 11 Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212 Beams:eCM = 100000 ! CM energy of collision ! 5) Settings for the hard-process generation SUSY:all = off ! Switches off ALL (~400) SUSY processes !SLHA:file = cards/split_stop.slha ! SLHA file SLHA:file = examples/Pythia8/split_stop.slha ! SLHA file SLHA:useDecayTable = on ! Read in SLHA DECAY tables [change for full scan] SLHA:readFrom = 2 SLHA:verbose = 0 ! verbosity # set process SUSY:gg2squarkantisquark = on ! stop pair production SUSY:qqbar2squarkantisquark = on ! stop pair production SUSY:qq2squarksquark = on ! stop pair production RHadrons:allow = on ! Allow stop-hadronization ! 5) Settings for the event generation process in the Pythia8 library. PartonLevel:MPI = on ! multiple interactions PartonLevel:ISR = on ! initial-state radiation PartonLevel:FSR = on ! final-state radiation HadronLevel:Hadronize = on ! hadronization ParticleDecays:xyMax = 129. ! radius of the cylinder in mm (CMS detector proportions) ParticleDecays:zMax = 300. ! half-high of the cylinder in mm ParticleDecays:limitCylinder = on !
