DecayNode describes the decay of a particle identified by its pdg code, into list of daughters.
Definition: DecayNode.h:23
std::vector< DecayNode > daughters
daughter decay nodes
Definition: DecayNode.h:48
DecayNode(int _pdg=0, const std::vector< DecayNode > &_daughters={})
Create new Decay node.
Definition: DecayNode.h:31
int pdg
pdg code of the particle
Definition: DecayNode.h:47
std::string print_node(unsigned int indent=0) const
Output a single node.
Definition: DecayNode.cc:30
bool operator==(const DecayNode &node1, const DecayNode &node2)
Compare two Decay Nodes: They are equal if All daughter decay nodes are equal or one of the daughter ...
Definition: DecayNode.cc:48
bool operator!=(const DecayNode &node1, const DecayNode &node2)
Not equal: See operator==.
Definition: DecayNode.cc:65
bool find_decay(const DecayNode &to_find) const
Check if the decay node contains the given decay tree.
Definition: DecayNode.cc:19
Abstract base class for different kinds of events.
