Public Functions Documentation

function Py8Collider

inline Py8Collider()

function ~Py8Collider

inline ~Py8Collider()

function clear

inline virtual void clear()

Reset this instance for reuse, avoiding the need for “new” or “delete”.

Reimplements: Gambit::ColliderBit::BaseCollider::clear

function addToSettings

inline void addToSettings(
    const std::string & command
)

Add a command to the list of settings used by “init”.

function banner

inline void banner(
    const std::string pythiaDocPath
)

Create a useless Pythia instance just to print the banner.

function init

inline virtual void init()

Initialize with no settings (error): override version.

Reimplements: Gambit::ColliderBit::BaseCollider::init

function init

inline virtual void init(
    const std::vector< std::string > & externalSettings
)

Note:

  • A string denoting the path to Pythia’s xmldoc directory is
  • assumed to be at the end of the settings vector:

Reimplements: Gambit::ColliderBit::BaseCollider::init

Initialize from some external settings: override version.

function init

inline void init(
    const std::string pythiaDocPath,
    const std::vector< std::string > & externalSettings,
    const SLHAea::Coll * slhaea =nullptr,
    std::ostream & os =std::cout
)

Note: This override is most commonly used in ColliderBit.

Initialize from some external settings.

function init_user_model

inline void init_user_model(

)

Initialize from some external settings. Special version of the init function for user defined models Needs to directly construct the new matrix elements (rather than use flags)

function init
