Constructor & Destructor Documentation

recocert::V0::V0 ( )

Default constructor.

recocert::V0::V0 ( const vertex::KVertex & vertex, const vertex::ChargedParticle * p1, const vertex::ChargedParticle * p2, const vertex::Vertex * primary )

Construct a V0 given a decay vertex and a primary vertex. Input parameters: vertex: the decay vertex p1: one of the decay particles p2: the other decay particle primary: the primary vertex (to be phased out)

Member Function Documentation

void recocert::V0::getData ( V0Data & data ) const

Fill structure with internal V0 data (to be phased out).

double recocert::V0::mass ( double mass ) const

Calculate the invariant mass of the V0 given individual masses of the decay particles. Returns invariant mass of V0 given input masses, assuming positive and negative particles have same mass. Input parameters: mass: mass of particles

double recocert::V0::mass ( double posMass, double negMass ) const

Calculate the invariant mass of the V0 given individual masses of the decay particles. Returns invariant mass of V0 given input masses. Input parameters: posMass: mass of positive particle negMass: mass of negative particle

const vertex::ChargedParticle * recocert::V0::neg ( ) const [inline]

Return pointer to the negative particle.

const vertex::ChargedParticle * recocert::V0::pos ( ) const [inline]

Return pointer to the positive particle.

const vertex::KVertex & recocert::V0::vertex ( ) const [inline]

Return a reference to the V0 vertex.
