public class VertexAnalysis extends Driver {
String vertexCollectionName = "TargetConstrainedV0Vertices";
protected void process(EventHeader event) {
List<Vertex> vertices = event.get(Vertex.class, vertexCollectionName);
for (Vertex v : vertices) {
Map<String, Double> vals = v.getParameters();
System.out.println(vals);
}
}
}
My questions is how do I know which (e- or e+) corresponds to particle 1 and particle 2 of the vertexed pair? Is there a pointer or do I need to write some software to make a sophisticated guess?
