Vertex reconstruction at the BGO-OD experiment* — •Patrick Bauer — Physikalisches Institut, Nussallee 12, D-53115 Bonn
The BGO-OD experiment at the ELSA accelerator facility in Bonn investigates the mechanisms of photoproduction of mesons from nucleons.
One focus is the associated strangeness production, i.e. γ p → (KY)+ or γ n → (KY)0. In order to identify such events,
the displacement of decay vertex of involved strange particles, relative to the primary vertex can be used.
Therefore a key feature of the experiment is the capability to reconstruct the decay vertices of particles decaying into multiple charged final state particles.
To achieve this the experiment uses the tracks of charged child particles, measured by the newly commissioned cylindrical MWPC, to determine the decay vertices of the mother-particles.
In this Talk the reconstruction procedure for the vertices and preliminary results will be presented.
