Detailed Description

Function Documentation

mT() [1/3]

double Rivet::mT ( const FourMomentum &  vis, const FourMomentum &  invis  )

inline

Calculate transverse mass of a visible and an invisible 4-vector

Note

This is implemented in terms of massless 3-vectors, ignoring actual masses in the 4-vectors.

mT() [2/3]

double Rivet::mT ( const FourMomentum &  vis, const Vector3 &  invis  )

inline

Calculate transverse mass of a visible 4-vector and an invisible 3-vector

Note

This is implemented in terms of massless 3-vectors, ignoring actual masses in the 4-vectors.
