Tracking of charged particles in the central region of the BGO-OD experiment using a cylindrical MWPC* — •Patrick Bauer for the BGO-OD collaboration — Physikalisches Institut, Bonn, Nußallee 1
The BGO-OD experiment at the ELSA accelerator facility at Bonn investigates the mechanisms of photoproduction of mesons from nucleons.
One focus is associated strangeness production, i.e. γ p → (K Y)+ or γ n → (K Y)0. Generally the strange-particle
decays yield multiple charged particles in the final state, as for example Λ K0 → (p π−) (π+ π−).
The capability to reconstruct precise tracks and vertices of reactions and decays is therefore crucial.
At BGO-OD, the charged particle trajectories are reconstructed using a cylindrical MWPC, which is surrounding the target
cell inside the BGO calorimeter. The reconstruction procedure, as well as its impact on the identification of reaction channels will be presented.
