Interfaces defined for the Pythia7::LundFragHandler class.
- Brief class description:
- This is the main handler class for Lund string fragmentation.
See also Pythia7::LundFragHandler
Name:
MinAngleType: Parameter
- Description:
- The effective angular cut-off in radians for recombination of partons, used in conjunction with M2Min.
Default value: 0.01
Minimum value: 0
Maximum value: 1
Name:
M2MinType: Parameter
- Description:
- The effective cut-off in squared mass, below which partons may be recombined to simplify (machine precision limited) kinematics of string fragmentation. (Default chosen to be of the order of a light quark mass, or half a typical light meson mass.)
Default value: 0.09
Minimum value: 0
Maximum value: 10
Name:
maxLoopType: Integer parameter
- Description:
- Number of maximun try alowed for a String Fragmentation [noUnit].The hadronization of a given string will be tried 8*maxLoop times and the M2Min and MinAngel will be increased every maxLoop attempts.
Default value: 100
Minimum value: 0
Maximum value: 1000
Name:
d_0Type: Parameter
- Description:
- Refers to the probability for reverse rapidity ordering of the final two hadrons in the standard Lund symmetric fragmentation scheme [GeV^-4].
Default value: 2.5
Minimum value: 0
Maximum value: 5
Name:
m_0Type: Parameter
- Description:
- Is with quark masses added, used to define the minimum allowableenergy of a colour-singlet jet system [GeV].
Default value: 1
Minimum value: 0
Maximum value: 5
Name:
deltaType: Parameter
- Description:
- Relative width of the smearing of the stopping point energy [noUnit].
Default value: 0.2
Minimum value: 0
Maximum value: 1
Name:
kType: Parameter
- Description:
- Represents the dependence on the mass of the final quark pair for defining the stopping point of the fragmentation [noUnit].Is strongly correlated to the choice of
Default value: 2
Minimum value: 0
Maximum value: 5
Name:
Wmin0Type: Parameter
- Description:
- Used to define, together with quark masses, the remaining energy below which the fragmentation of a jet system is stopped and two final hadrons formed. For the Standard Lund symmetric fragmentation scheme [in GeV]
Default value: 0.8
Minimum value: 0
Maximum value: 10
Name:
FlavourGeneratorType: Reference to objects of class Pythia7::LundFlavourGenerator
- Description:
- Pointer to the FlavourGenerator object used by the fragmentation handler. Should derive from Pythia7::LundFlavourGenerator.
Name:
ClusterCollapserType: Reference to objects of class ThePEG::ClusterCollapser
- Description:
- Pointer to a ThePEG::ClusterCollapser object used by the Lund fragmentation handler to avoid too small strings in the fragmentation.
Name:
ZGeneratorType: Reference to objects of class ThePEG::ZGenerator
- Description:
- Pointer to the ZGenerator object used by the fragmentation handler. Should derive from Pythia7::LundZGenerator.
Name:
PtGeneratorType: Reference to objects of class ThePEG::PtGenerator
- Description:
- The PtGenerator object used by the Lund fragmentation handler. Should derive from Pythia7::LundPtGenerator.
There may be interfaces inherited from the ThePEG::HadronizationHandler class.
