Modules
Here is a list of all modules:
oHadronization ClassesThese classes are used for the Hadronization
oHelicity classesThese classes are used to include spin correlation effects
oInterfaces classesThese classes are used to interface to external tools, like matrix element generators, jet finder algorithms, etc
oMatrixElement classesThese classes are used for the hard process generation
oMatchbox classesHard process generation at NLO using Catani-Seymour subtraction and NLO matching
oModels classesThese classes are used for specific models, like the Standard Model
oPDF classesThese classes are used for particle density functions
oShower classesThese classes are used for the Showering
oDipoleShower classesClasses implementing the coherent dipole shower algorithm
oAnalysis classesThese classes are used to perform analysis of the events generated by Herwig
oUnderlyingEvent classesThese classes are used for the underlying event
oUtilities classesThese classes provide general utilities
oDecay classesThese classes perform the decays
oParticle Data classParticle properties classses
