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.
8 Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212
9 Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212
10 Beams:eCM = 14000. ! CM energy of collision, LHC
12 ! 2) Settings that are used in the main program.
13 Main:numberOfEvents = 1000 ! number of events to generate
14 Main:numberToList = 1 ! number of events to print
15 Main:timesToShow = 20 ! show how far along run is this many times
16 Main:timesAllowErrors = 10 ! abort run after this many flawed events
17 Main:showChangedSettings = on ! print changed flags/modes/parameters
18 #Main:showAllSettings = on ! print all flags/modes/parameters
19 Main:showOneParticleData = 32 ! print data for this particular particle
20 Main:showChangedParticleData = on ! print changed particle and decay data
21 #Main:showChangedResonanceData = on ! also print changed resonance data
22 #Main:showAllParticleData = on ! print all particle and decay data
23 #Main:showAllStatistics = on ! more statistics on multiple interactions
25 ! 3) Settings for hard-process generation internal to Pythia8.
26 NewGaugeBoson:ffbar2gmZZprime = on ! full gamma*/Z^0/Z'^0 production
27 32:m0 = 1000. ! Z' mass
28 32:mMin = 200. ! cut off gamma*/Z^0 peaks
30 ! 4) Switch off some key components of the simulation, for comparisons.
31 #PartonLevel:all = off ! stop after hard process
32 #PartonLevel:MI = off ! no multiple interactions
33 #PartonLevel:ISR = off ! no initial-state radiation
34 #PartonLevel:FSR = off ! no final-state radiation
35 HadronLevel:all = off ! stop after parton level
36 #HadronLevel:Hadronize = off ! no hadronization
37 #HadronLevel:Decay = off ! no decays
39 ! 5) Any other changes you desire.
