Study of the Reconstruction Methods in Searching for the Pentaquark at the Hermes

  • Four different reconstruction methods are used to prove that the existence of a narrow baryon state in the quasi-real photo-production on a deuterium target through the decay channel pK0s→pπ+π- is independent of the reconstruction method, in which a peak is found around 1530MeV.

Abstract: Four different reconstruction methods are used to prove that the existence of a narrow baryon state in the quasi-real photo-production on a deuterium target through the decay channel pK0s→pπ+π- is independent of the reconstruction method, in which a peak is found around 1530MeV.
