! main30.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 settings here are illustrative, not always physics-motivated. ! 1) Settings used in the main program. Main:numberOfEvents = 100 ! number of events to generate Main:timesAllowErrors = 3 ! how many aborts before run stops ! 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 = 0 ! print event information n times Next:numberShowProcess = 0 ! print process record n times Next:numberShowEvent = 5 ! print event record n times ! 3) Beam parameter settings. Values below agree with default ones. Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212 Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212 Beams:eCM = 8000. ! CM energy of collision ! BeamRemnants:primordialKT = off ! 4) Settings for the hard-process generation. SLHA:file = slha1-example.spc ! Sample SLHA1 spectrum SUSY:all = on ! Switches on ALL (~400) SUSY processes ! 5) Switch on/off the key event generation steps. HadronLevel:all = on ! no decays PartonLevel:ISR = on PartonLevel:FSR = on PartonLevel:MPI = on ! Optionally select only specific sparticle codes in the final state SUSY:idA = 1000021 ! 0: all SUSY:idB = 1000004 ! 0: all ! 6) Other settings. Can be expanded as desired. Tune:pp = 6 ! use Tune 4Cx ParticleDecays:limitTau0 = on ! set long-lived particle stable ... ParticleDecays:tau0Max = 10 ! ... if c*tau0 > 10 mm
