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 | ||
5 | ! 1) Settings used in the main program. | |
6 | Main:numberOfEvents = 1000 ! number of events to generate | |
7 | ||
8 | ! 2) Settings related to output in init(), next() and stat(). | |
9 | Init:showChangedSettings = on ! list changed settings | |
10 | Init:showChangedParticleData = off ! list changed particle data | |
11 | Next:numberCount = 100 ! print message every n events | |
12 | Next:numberShowInfo = 2 ! print event information n times | |
13 | Next:numberShowProcess = 2 ! print process record n times | |
14 | Next:numberShowEvent = 1 ! print event record n times | |
15 | ||
16 | ! 3) Include photon-in-proton: use MRST2004qed set | |
17 | PDF:useLHAPDF = on | |
18 | PDF:LHAPDFset = MRST2004qed.LHgrid | |
19 | ||
20 | ! 4 Two options to select hard process to generate. | |
21 | ! A) Read in external event with incoming photon in the ME, | |
22 | ! from pre-generated .lhe file (thanks to SANC and R. Sadykov). | |
23 | #Beams:frameType = 4 ! read in LHE file | |
24 | #Beams:LHEF = photoninproton.lhe ! name of LHE file | |
25 | ! B) Select internal Pythia processes. | |
26 | ! Use that default is 14 TeV pp,so don't set beams. | |
27 | WeakBosonAndParton:fgm2Wf = on ! fermion gamma -> W+- fermion' | |
28 | ||
29 | ! 5) Test flags to simplify generation | |
30 | PartonLevel:MPI = off ! no multiparton interactions | |
31 | #PartonLevel:ISR = off ! initial-state radiation | |
32 | #PartonLevel:FSR = off ! no final-state radiation | |
33 | HadronLevel:Hadronize = off ! no hadronization |
