Function Documentation

addDecay()

void addDecay ( MCParticleGraph::GraphParticle &  mother, MCParticleGraph::GraphParticle &  daughter  )

inline

Add decay information between two particles.

If the daughter has already a mother attached, an exception of type DaughterHasMotherError is thrown.

Parameters

mother	The mother particle which decays.
daughter	The daughter particle in which the mother particle decays.

Definition at line 302 of file MCParticleGraph.h.

  {
    if (this != mother.m_graph || this != daughter.m_graph) throw NotSameGraphError();
    //if (daughter.getMother() != NULL) throw DaughterHasMotherError();
    m_decays.insert(DecayLine(mother.m_vertexId, daughter.m_vertexId));
    daughter.m_primary = false;
  }

addParticle()

MCParticleGraph::GraphParticle & addParticle ( )

inline

Add new particle to the graph.

Set the values of the returned reference to determine the particle parameters.

Returns

A reference to the added particle.

Definition at line 294 of file MCParticleGraph.h.

  {
    unsigned int index = m_particles.size() + 1;
    MCParticleGraph::GraphParticle* p = new (m_particles.add()) MCParticleGraph::GraphParticle(this, index);
    return *p;
  }

clear()

void clear ( )

inline

Reset particles and decay information to make the class reusable.

New particles can be added again after a call to clear(), e.g. in the next event

Definition at line 287 of file MCParticleGraph.h.

  {
    m_particles.clear();
    m_decays.clear();
  }

getMother()

MCParticle * getMother ( ) const

inline

Returns a pointer to the mother particle.

NULL if the particle doesn't have a mother.

Returns

A pointer to the mother particle. NULL if no mother was defined for the particle.

Definition at line 600 of file MCParticle.h.

  {
    if (m_mother == 0)
      return nullptr;
    fixParticleList();
    return static_cast<MCParticle*>(m_plist->At(m_mother - 1));
  }

isInitial()

bool isInitial ( ) const

inline

Check if particle is an initial particle such as ISR.

Definition at line 590 of file MCParticle.h.

  {
    return hasStatus(c_Initial);
  }

isPrimaryParticle()

bool isPrimaryParticle ( ) const

inline

Check if particle is a primary particle which was created by the generator (and not, for example material interaction)

Definition at line 595 of file MCParticle.h.

  {
    return hasStatus(c_PrimaryParticle);
  }

isVirtual()

bool isVirtual ( ) const

inline

Check if particle is virtual.

Definition at line 575 of file MCParticle.h.

  {
    bool virtuality = hasStatus(c_IsVirtual);
    if (!virtuality) {
      double E2 = m_energy * m_energy;
      double m2 = m_mass * m_mass;
      double p2 = m_momentum_x * m_momentum_x;
      p2 += m_momentum_y * m_momentum_y;
      p2 += m_momentum_z * m_momentum_z;
 
      virtuality = (fabs(E2 - (p2 + m2)) > c_epsilon * E2);
    }
    return virtuality;
  }
