private |
c++ translation of subroutine of same name from alpsho.f.
Label all particles with status between ISTLO and ISTHI (until a particle with status ISTOP is found) as final-state, call calsim_m and then put labels back to normal. This version keeps only all IST=1 particles rejected by caldel as daughters of vetoed heavy-quark mothers: jets complementary to those reconstructed by caldel.
|
private |
Deletes particles from partonsToMatch_ and particlesToCluster_ vectors so that these contain only the partons to match to the jets and the particles used to build jets respectively.
By and large the candidates for deletion are: vector bosons and their decay products, Higgs bosons, photons as well as primary, i.e. present in the lowest multiplicity process, heavy quarks and any related decay products.
|
private |
Deletes particles from partonsToMatch_ and particlesToCluster_ vectors so that these contain only the partons to match to the jets and the particles used to build jets respectively.
The candidates are chosen according to the information passed from madgraph.
|
protectedvirtual |
Make a simple clone of this object.
Reimplemented from Herwig::QTildeShowerHandler.
|
protectedvirtual |
Initialize this object after the setup phase before saving an EventGenerator to disk.
InitException | if object could not be initialized properly. |
Reimplemented from Herwig::QTildeShowerHandler.
|
protectedvirtual |
Initialize this object.
Called in the run phase just before a run begins.
Reimplemented from Herwig::QTildeShowerHandler.
|
private |
Allows printing of debug output and sanity checks like total momentum consrvation to be carried out.
debugLevel = -1, 0, ...5 = no debugging, minimal debugging, ... verbose.
|
protectedvirtual |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from Herwig::QTildeShowerHandler.
|
private |
Get the particles from eventHandler()->currentEvent()->...
filling the particle pairs showeredISHs_, showeredISPs_, showeredRems_ and the particle pointer vector showeredFSPs_.
|
static |
The standard Init function used to initialize the interfaces.
Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.
|
privatedelete |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
void Herwig::FxFxHandler::persistentInput | ( | PersistentIStream & | is, |
int | version | ||
) |
Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
void Herwig::FxFxHandler::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
|
virtual |
Hook to allow vetoing of event after showering hard sub-process as in e.g.
MLM merging.
Reimplemented from Herwig::QTildeShowerHandler.
|
staticprivate |
The static object used to initialize the description of this class.
Indicates that this is a concrete class with persistent data.

Final-state outgoing partICLEs prior to showering (i.e.
from lastXCombPtr).

This same list is the starting point for determining partonsToMatch_ for the case of merging in heavy quark production.

Initial-state incoming partons prior to showering (i.e.
from lastXCombPtr).
