Detailed Description

Final state particles boosted to the hadronic center of mass system.

NB. The DIS scattered lepton is not included in the final state particles.

Constructor & Destructor Documentation

◆ DISFinalState() [1/2]

Rivet::DISFinalState::DISFinalState ( const Cut &  c,
DISFrame  boosttype 
)
inline

Constructor with explicit cuts to define final-state particles.

Note
The cuts will be applied before the boost, e.g. to express detector acceptance.
Todo:
Add a second optional Cut argument for post-boost cuts.

◆ DISFinalState() [2/2]

Rivet::DISFinalState::DISFinalState ( DISFrame  boosttype,
const Cut &  c 
)
inline

Constructor with explicit cuts to define final-state particles.

Note
The cuts will be applied before the boost, e.g. to express detector acceptance.
Todo:
Add a second optional Cut argument for post-boost cuts.
Deprecated:
The DISKinematics has no parameters, hence explicitly passing it as an arg shouldn't be necessary.

◆ accept()

virtual bool Rivet::FinalState::accept ( const Particle p) const
virtualinherited

Decide if a particle is to be accepted or not.

Todo:
Rename to _accept or acceptFinal?

Reimplemented in Rivet::FinalPartons.

◆ apply()

◆ before()

bool Rivet::Projection::before ( const Projection p) const
inherited

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.
