! File: main32.cmnd ! This file contains commands to be read in for a Pythia8 run. ! Lines not beginning with a letter or digit are comments. ! Names are case-insensitive - but spellings-sensitive! ! The changes here are illustrative, not always physics-motivated. ! 1) Settings that will be used in a main program. Main:numberOfEvents = 100 ! number of events to generate Main:timesToShow = 10 ! show how far along run is this many times Main:timesAllowErrors = 3 ! abort run after this many flawed events Main:showChangedSettings = on ! print changed flags/modes/parameters #Main:showAllSettings = on ! print all flags/modes/parameters Main:showChangedParticleData = on ! print changed particle and decay data #Main:showAllParticleData = on ! print all particle and decay data ! 2) Beam parameter settings. Values below agree with default ones. Beams:idA = 2212 ! first beam, p = 2212, pbar = -2212 Beams:idB = 2212 ! second beam, p = 2212, pbar = -2212 Beams:eCM = 14000. ! CM energy of collision ! 3) Pick processes and kinematics cuts. Charmonium:gg2QQbar[3S1(1)]g = on ! colour singlet charmonium production Charmonium:gg2QQbar[3P0(1)]g = on ! " Charmonium:gg2QQbar[3P1(1)]g = on ! " Charmonium:gg2QQbar[3P2(1)]g = on ! " PhaseSpace:pTHatMin = 20. ! minimum pT of hard process
