Detailed Description

Function Documentation

oppCharge()

bool Rivet::oppCharge ( const Particle & a, const Particle & b )

inline

Return true if Particles a and b have the exactly opposite charge

Note

Two neutrals returns false

References Rivet::Particle::charge3().

oppSign()

bool Rivet::oppSign ( const Particle & a, const Particle & b )

inline

Return true if Particles a and b have the opposite charge sign.

Note

Two neutrals returns false

References Rivet::Particle::charge3(), and sign().

sameCharge()

bool Rivet::sameCharge ( const Particle & a, const Particle & b )

inline

Return true if Particles a and b have the same charge (including neutral)

Note

Two neutrals returns true

References Rivet::Particle::charge3().

sameSign()

bool Rivet::sameSign ( const Particle & a, const Particle & b )

inline

Return true if Particles a and b have the same charge sign

Note

Two neutrals returns true
