| 2 | ! This file contains commands to be read in for a Pythia8 run. |
---|
| 3 | ! Lines not beginning with a letter or digit are comments. |
---|
| 4 | ! Names are case-insensitive - but spellings-sensitive! |
---|
| 5 | ! The changes here are illustrative, not always physics-motivated. |
---|
| 6 | |
---|
| 7 | ! 1) Settings that are used in the main program. |
---|
| 8 | Main:numberOfEvents = 1000 ! number of events to generate |
---|
| 9 | Main:timesAllowErrors = 10 ! abort run after this many flawed events |
---|
| 10 | |
---|
| 11 | ! 2) Settings related to output in init(), next() and stat(). |
---|
| 12 | Init:showChangedSettings = on ! list changed settings |
---|
| 13 | Init:showChangedParticleData = on ! list changed particle data |
---|
| 14 | #Init:showChangedResonanceData = on ! also print changed resonance data |
---|
| 15 | Init:showOneParticleData = 25 ! print data for this particular particle |
---|
| 16 | Next:numberCount = 100 ! print message every n events |
---|
| 17 | Next:numberShowInfo = 1 ! print event information n times |
---|
| 18 | Next:numberShowProcess = 1 ! print process record n times |
---|
| 19 | Next:numberShowEvent = 0 ! print event record n times |
---|
| 20 | Stat:showPartonLevel = on ! more statistics on MPI |
---|
| 21 | |
---|
| 22 | ! 3) Beam settings. |
---|
| 23 | Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212 |
---|
| 24 | Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212 |
---|
| 25 | Beams:eCM = 14000. ! CM energy of collision, LHC |
---|
| 26 | |
---|
| 27 | ! 4) Settings for hard-process generation internal to Pythia8. |
---|
| 28 | HiggsSM:gg2H = on ! Higgs production by gluon-gluon fusion |
---|
| 29 | 25:m0 = 123.5 ! Higgs mass |
---|
| 30 | |
---|
| 31 | ! 5) Switch off some key components of the simulation, for comparisons. |
---|
| 32 | #PartonLevel:all = off ! stop after hard process |
---|
| 33 | #PartonLevel:MPI = off ! no multiparton interactions |
---|
| 34 | #PartonLevel:ISR = off ! no initial-state radiation |
---|
| 35 | #PartonLevel:FSR = off ! no final-state radiation |
---|
| 36 | #HadronLevel:all = off ! stop after parton level |
---|
| 37 | #HadronLevel:Hadronize = off ! no hadronization |
---|
| 38 | #HadronLevel:Decay = off ! no decays |
---|
| 39 | |

| 40 | ! 6) Any other changes you desire. |
