For the inclusive case, the final state jets are now fully defined,
and the jets can be recovered using the methods described below. In
the exclusive case, the final state jets are defined by setting either
the stopping parameter
:
void findJetsD(float dcut);
or by forcing the final state to decompose into jets:
void findJetsN(int N);
The value at which the final state changes from to
jets can be recovered using the method
float getDMerge(int N) const;
In the case of an analysis, the variable
may be
used. The final state jets are defined by the method
void findJetsY(float yCut);
and the
value at which the final state changes from
to jets can be recovered using the method
float getYMerge(int N) const;
By default,
is defined as in equation 4, where
is
taken to be the total energy in the event. The
value can be
set by the user if required:
void setECut(float ECut);
The KtEvent object has the following methods for recovering its final state jets:
std::vector<KtLorentzVector> getJets() const;
Returns jets without sorting.
std::vector<KtLorentzVector> getJetsE() const;
Returns jets in order of decreasing energy.
std::vector<KtLorentzVector> getJetsEt() const;
Returns jets in order of decreasing transverse energy.
std::vector<KtLorentzVector> getJetsPt() const;
Returns jets in order of decreasing transverse momentum.
std::vector<KtLorentzVector> getJetsRapidity() const;
Returns jets in order of decreasing rapidity.
std::vector<KtLorentzVector> getJetsEta() const;
Returns jets in order of decreasing pseudorapidity.
KtLorentzVector getJet(const KtLorentzVector &) const;
Returns the final state jet which contained the input particle
KtLorentzVector. Note that this method is only available if
KtLorentzVectors were used as input in the KtEvent
constructor.
std::vector<const KtLorentzVector*> & getConstituents() const;
Returns a vector of pointers to all the input objects in the KtEvent.
std::vector<KtLorentzVector> copyConstituents() const;
Returns a vector of copies of the input objects in the KtEvent.
int getNConstituents() const;
Returns the number of objects in the KtEvent.
The parameters of a particular KtEvent can be retrieved using the methods
float getETot() const;
int getType() const;
int getAngle() const;
int getRecom() const;
float getECut() const;
bool isInclusive() const;
