! 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:numberToList = 1              ! number of events to print
Main:timesToShow = 20              ! show how far along run is
Main:showChangedSettings = on      ! print changed flags/modes/parameters
Main:showChangedParticleData = on  ! print changed particle and decay data

! 2) 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 = 14000.                 ! CM energy of collision

! 3) Settings for the hard-process generation.
HardQCD:all = on                   ! switch on all QCD jet + jet processes
PromptPhoton:all = on              ! swich on gamma + jet and gamma + gamma 
PhaseSpace:pTHatMin = 50.          ! minimal pT sacale in process 

! 4) Settings for the event generation process in the Pythia8 library.
#PartonLevel:MI = off               ! no multiple interactions
#PartonLevel:ISR = off              ! no initial-state radiation 
#PartonLevel:FSR = off              ! no final-state radiation
#HadronLevel:Hadronize = off        ! no hadronization
SpaceShower:pT0Ref = 2.0           ! dampening of pT -> 0 divergence
MultipleInteractions:pTmin = 3.0   ! lower pT cutoff for interactions
