! File: main16.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) Settings that are used in the main program.
Main:numberOfEvents = 1000         ! number of events to generate
Main:timesAllowErrors = 10         ! abort run after this many flawed events

! 2) Settings related to output in init(), next() and stat().
Init:showChangedSettings = on      ! list changed settings
Init:showChangedParticleData = on  ! list changed particle data
#Init:showChangedResonanceData = on ! also print changed resonance data
Init:showOneParticleData = 25      ! print data for this particular particle
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 = 0           ! print event record n times
Stat:showPartonLevel = on          ! more statistics on MPI  

! 3) 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

! 4) Settings for hard-process generation internal to Pythia8.
HiggsSM:gg2H = on                  ! Higgs production by gluon-gluon fusion
25:m0 = 123.5                      ! Higgs mass

! 5) Switch off some key components of the simulation, for comparisons.
#PartonLevel:all = off              ! stop after hard process 
#PartonLevel:MPI = off              ! no multiparton 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
