/CollTools [ Modules ]

[ Top ] [ Modules ]

PURPOSE

This module contains routines needed by the modules DoColl_...

CollTools/ConvertToAnti [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine ConvertToAnti(part)

subroutine ConvertToAnti(part, partNEW)

subroutine ConvertToAnti(parts)

PURPOSE

Convert particle(s) to anti-particle(s).

INPUTS

OUTPUT

This depends on input/output combinations:

Case 1:

Case 2:

  • type(particle) :: partNEW (The input values are not modified; all information is transfered to a new copy and this copy is modified)

Case 3:

NOTES

This function is overloaded.

CollTools/SetSomeDefaults_PY [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine SetSomeDefaults_PY

PURPOSE

Set some default values for (new) PYTHIA/JETSET.

CollTools/SetSomeDefaults_PY_Hermes [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine SetSomeDefaults_PY_Hermes

PURPOSE

Set some default values for (new) PYTHIA/JETSET as tuned by the HERMES collab. Meant to be called after a call to SetSomeDefaults_PY.

NOTES

To use this, this routine has to be called immediately before a call to InitPythia (when used for "Virtual Photons").

Parameters-setting for own calculation are not set here, but in "InitPythia". Some "useless" paramtere changings are excluded or marked with "(???)". No support for MSTP(199)=1 ("use of radgen")!!!

CollTools/SetSomeDefaults_FR [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine SetSomeDefaults_FR

PURPOSE

Set some default values for FRITIOF and (old) PYTHIA/JETSET.

CollTools/SetVectorFromPYJETS [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine SetVectorFromPYJETS(Part, HardScaleQ2)

PURPOSE

Take the information from the PYJETS common block and set the output particle array Part accordingly.

INPUTS

OUTPUT

  • integer, OPTIONAL :: iDiffrRho -- if given and a diffractive rho was generated, this returns the index
  • "Part" chaged

CollTools/ConvertInPartPythia [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine ConvertInPartPythia(ID,IDc)

PURPOSE

Reduce variety of incoming mesons to some simpler manyfold (special for Pythia).

CollTools/ConvertInPartFritiof [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine ConvertInPartPythia(ID,IDc)

PURPOSE

Reduce variety of incoming mesons to some simpler manyfold (special for Fritiof).

CollTools/ReduceCharge [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine ReduceCharge(ID,IZ,IZc)

PURPOSE

Reduce charge of incoming particle, if it is N, N* or Delta (e.g. Delta++ is mapped onto a Delta+).

CollTools/CorrectChargeVector [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine CorrectChargeVector(Part,DeltaQ)

PURPOSE

Correct the Charge of the outgoing particles of the whole event. If deltaQ>0 one has to add positive charges. This is necessary, if ReduceCharge changed the charge of an incoming particle.

CollTools/SetSomeDefaults_PY_Job [ Subroutines ]

[ Top ] [ CollTools ] [ Subroutines ]

NAME

subroutine SetSomeDefaults_PY_Job

PURPOSE

Read in the namelist "pythia" from the jobcard.

NOTES

  • only at the first call, the namelist is actually read in, in further calls the stored modifications are "replayed"
  • in order to keep the names in the namelist as usual, the arrays used in the common blocks are renamed.
  • not ALL Pythia parameters can be set, please see NAMELIST /pythia/
