! File: main17.cmnd ! This file contains commands to be read in for a Pythia8 run. ! Lines not beginning with a letter or digit are comments. ! Names are case-insensitive - but spellings-sensitive! ! The changes here are illustrative, not always physics-motivated. ! 1) Beam settings. Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212 Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212 Beams:eCM = 14000. ! CM energy of collision, LHC ! 2) Settings that are used in the main program. Main:numberOfEvents = 1000 ! number of events to generate Main:numberToList = 1 ! number of events to print Main:timesToShow = 20 ! show how far along run is this many times Main:timesAllowErrors = 10 ! abort run after this many flawed events Main:showChangedSettings = on ! print changed flags/modes/parameters #Main:showAllSettings = on ! print all flags/modes/parameters Main:showOneParticleData = 32 ! print data for this particular particle Main:showChangedParticleData = on ! print changed particle and decay data #Main:showChangedResonanceData = on ! also print changed resonance data #Main:showAllParticleData = on ! print all particle and decay data #Main:showAllStatistics = on ! more statistics on multiple interactions ! 3) Settings for hard-process generation internal to Pythia8. NewGaugeBoson:ffbar2gmZZprime = on ! full gamma*/Z^0/Z'^0 production 32:m0 = 1000. ! Z' mass 32:mMin = 200. ! cut off gamma*/Z^0 peaks ! 4) Switch off some key components of the simulation, for comparisons. #PartonLevel:all = off ! stop after hard process #PartonLevel:MI = off ! no multiple interactions #PartonLevel:ISR = off ! no initial-state radiation #PartonLevel:FSR = off ! no final-state radiation HadronLevel:all = off ! stop after parton level #HadronLevel:Hadronize = off ! no hadronization #HadronLevel:Decay = off ! no decays ! 5) Any other changes you desire.
