c6b60c38 | 1 | ! main62.cmnd. |
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 settings here are illustrative, not always physics-motivated. | |
6 | ||
7 | ! 1) Settings used in the main program. | |
8 | Main:timesAllowErrors = 3 ! how many aborts before run stops | |
9 | ||
10 | ! 2) Settings related to output in init(), next() and stat(). | |
11 | Init:showChangedSettings = on ! list changed settings | |
12 | Init:showAllSettings = off ! list all settings | |
13 | Init:showChangedParticleData = on ! list changed particle data | |
14 | Init:showAllParticleData = off ! list all particle data | |
15 | Next:numberCount = 1000 ! print message every n events | |
16 | Next:numberShowLHA = 1 ! print LHA information n times | |
17 | Next:numberShowInfo = 1 ! print event information n times | |
18 | Next:numberShowProcess = 1 ! print process record n times | |
19 | Next:numberShowEvent = 1 ! print event record n times | |
20 | Stat:showPartonLevel = off ! additional statistics on MPI | |
21 | ||
22 | ! 3) PDF settings. Default is to use internal PDFs | |
23 | PDF:useLHAPDF = on | |
24 | ! some pdf sets examples: cteq61.LHpdf cteq61.LHgrid MRST2004nlo.LHgrid | |
25 | PDF:LHAPDFset = MRST2001lo.LHgrid | |
26 | ! Allow extrapolation of PDF's beyond x and Q2 boundaries, at own risk. | |
27 | ! Default behaviour is to freeze PDF's at boundaries. | |
28 | PDF:extrapolateLHAPDF = on | |
29 | ||
30 | ! 4) Other common settings. | |
31 | 6:m0 = 175. ! same m_t as Pythia 6.4 to compare | |
32 | #ParticleDecays:limitTau0 = on ! set long-lived particle stable ... | |
33 | #ParticleDecays:tau0Max = 10 ! ... if c*tau0 > 10 mm | |

35 | ! 5) The number of subruns to execute. | |
36 | Main:numberOfSubruns = 2 | |
37 | ||
38 | ! 6) Information specific to the first subrun | |
39 | Main:subrun = 1 ! matches readFile( ..., 1) | |
40 | Beams:frameType = 4 ! use LHEF input | |
41 | Beams:LHEF = ttbar.lhe ! first LHEF event file | |
42 | ||
43 | ! 7) Information specific to the second subrun | |
44 | Main:subrun = 2 ! matches readFile( ..., 2) | |
45 | Beams:newLHEFsameInit = on ! no reinitialization needed/wanted | |
46 | Beams:LHEF = ttbar2.lhe ! second LHEF event file |
