! This file contains commands to be read in for a Pythia8 run.

! Example file for producing long-lived particles or dark matter companions
! Models include (1) scalar -> lepton + DM (2) SU(2) n-plets with mixing
! Small couplings or large suppression scale result in long-lived particles.

! 1) Settings used in the main program.
Main:numberOfEvents = 1000        ! 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 = 2            ! print event information n times
Next:numberShowProcess = 2         ! print process record n times
Next:numberShowEvent = 2           ! 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 = 13000.                 ! CM energy of collision

! 4) Masses and couplings
! Masses
56:m0 = 500.0    ! Scalar lepton
52:m0 = 100.0    ! Dark matter

! Couplings
DM:yuk1 = 1.0e-7  ! Yukawa coupling to electron
DM:yuk2 = 0.0     ! to muon
DM:yuk3 = 0.0     ! to tau

DM:Nplet = 3      ! Nplet = 1:doublet; 2: triplet; 3: quintuplet
DM:M1 = 350.0     ! Mass of Singlet
DM:M2 = 200.0     ! Mass of Nplet
DM:Lambda = 1000. ! Suppression scale

! 5) Process selection
DM:qqbar2DY = on  ! Drell-Yan production of
DM:DYtype = 1     ! 1: scalar; 2: singly charged partner
                  ! 3: doubly charged partner; 4: neutral + charged partner

! 6) Lifetimes
56:tauCalc = false ! turn off automatic lifetime calculation
56:tau0 = 100      ! specify the lifetime to use

! 7) Settings for the event generation process in the Pythia8 library.
PartonLevel:MPI = off              ! no multiparton interactions
PartonLevel:ISR = off              ! no initial-state radiation
PartonLevel:FSR = off              ! no final-state radiation
HadronLevel:Hadronize = off        ! no hadronization
