2 ! This file contains commands to be read in for a Pythia8 run.
3 ! Lines not beginning with a letter or digit are comments.
5 ! 1) Settings used in the main program.
6 Main:numberOfEvents = 1000 ! number of events to generate
7 Main:numberToList = 1 ! number of events to print
8 Main:timesToShow = 20 ! show how far along run is
9 Main:timesAllowErrors = 5 ! allow a few failures before quitting
10 Main:showChangedSettings = on ! print changed flags/modes/parameters
11 Main:showChangedParticleData = on ! print changed particle and decay data
13 ! 2) Beam parameter settings. Incoming beams do not radiate.
14 Beams:idA = -11 ! ficititious incoming e+
15 Beams:idB = 11 ! ficititious incoming e-
16 PDF:lepton = off ! no radiation off ficititious e+e-
17 Beams:eCM = 500. ! CM energy of collision
19 ! 3) Set up properties of the GeneralResonance and its decay channels.
20 ! id:all = name antiName spinType chargeType colType m0 mWidth mMin mMax tau0
21 999999:all = GeneralResonance void 1 0 0 500. 1. 0. 0. 0.
22 ! id:addChannel = onMode bRatio meMode product1 product2 ...
23 ! Note: sum of branching ratios automatically rescaled to 1.
24 ! Current channels illustrative only; insert your own decay list.
25 999999:addChannel = 1 0.2 101 1 -1 ! -> d dbar
26 999999:addChannel = 1 0.2 101 6 -6 ! -> t tbar
27 999999:addChannel = 1 0.2 101 15 -15 ! -> tau- tau+
28 999999:addChannel = 1 0.2 101 24 -24 ! -> W+ W-
29 999999:addChannel = 1 0.2 101 25 25 ! -> h0 h0
31 ! 4) Tell that also long-lived should decay.
32 13:mayDecay = true ! mu+-
33 211:mayDecay = true ! pi+-
34 321:mayDecay = true ! K+-
35 130:mayDecay = true ! K0_L
36 2112:mayDecay = true ! n
