A Topological vertex reconstruction algorithm for hadronic jets

Abstract The algorithm described reconstructs a set of topological vertices each associated with an independent subset of the charged tracks in a hadronic jet. Vertices are reconstructed by associating tracks with 3D spatial regions according to a vertex probability function which is based on the trajectories and position resolution of the tracks. SLD data is used to illustrate the performance of the algorithm with emphasis on the application to Z 0 → b b events.
