is there any reason why in the TLorentzVector Class the method et() is not implemented?

In CLHEP LorentzVector.h
pcitapiww.cern.ch/cgi-bin/clhep/ … web-markup

inline double et() const;
// Transverse energy.

Thanks

I’m using CLHEP 2.0.1.0 and HepMC::LorentzVector.et() works fine for me. Perhaps you need to recompile?

In the CVS version, I have implemented the following methods:

inline Double_t Et2() const;
// Transverse energy squared.

inline Double_t Et() const;
// Transverse energy.

inline Double_t Et2(const TVector3 &) const;
// Transverse energy w.r.t. given axis squared.

inline Double_t Et(const TVector3 &) const;
// Transverse energy w.r.t. given axis.
