class Gambit::ColliderBit::Py8Collider;

A specializable, recyclable class interfacing ColliderBit and Pythia.

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

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 #

inline void init(
    const std::string pythiaDocPath,
    const std::vector< std::string > & externalSettings,
    std::ostream & os
)

Initialize from some external settings, assuming no given SLHAea instance.

function init_user_model #

inline void init_user_model(
    const std::string pythiaDocPath,
    const std::vector< std::string > & externalSettings,
    std::ostream & os
)

Initialize from some external settings, assuming no given SLHAea instance.

function nextEvent #

inline void nextEvent(
    EventT & event
) const

Event generation for any Pythia interface to Gambit.

function xsec_fb #

inline virtual double xsec_fb() const

Report the total or process-specific cross section (in fb or pb).

Reimplements: Gambit::ColliderBit::BaseCollider::xsec_fb

function xsec_fb #

inline virtual double xsec_fb(
    int process_code
) const

Reimplements: Gambit::ColliderBit::BaseCollider::xsec_fb

function xsec_pb #

inline virtual double xsec_pb() const

Reimplements: Gambit::ColliderBit::BaseCollider::xsec_pb

function xsec_pb #

inline virtual double xsec_pb(
    int process_code
) const

Reimplements: Gambit::ColliderBit::BaseCollider::xsec_pb

function xsecErr_fb #

inline virtual double xsecErr_fb() const

Report the uncertainty in the total or process-specific cross section (in fb or pb).

Reimplements: Gambit::ColliderBit::BaseCollider::xsecErr_fb

function xsecErr_fb #

inline virtual double xsecErr_fb(
    int process_code
) const

Reimplements: Gambit::ColliderBit::BaseCollider::xsecErr_fb

function xsecErr_pb #

inline virtual double xsecErr_pb() const

Reimplements: Gambit::ColliderBit::BaseCollider::xsecErr_pb

function xsecErr_pb #

inline virtual double xsecErr_pb(
    int process_code
) const

Reimplements: Gambit::ColliderBit::BaseCollider::xsecErr_pb

function process_code #

inline virtual int process_code() const

Report an integer process code for the last generated event.

Reimplements: Gambit::ColliderBit::BaseCollider::process_code

function all_active_process_codes #

inline virtual std::vector< int > all_active_process_codes() const

Report the list of all active process codes.

Reimplements: Gambit::ColliderBit::BaseCollider::all_active_process_codes

function pythia #

inline const PythiaT * pythia() const

Get the Pythia instance.

function SetupMatchingUserHook #

inline bool SetupMatchingUserHook()
