Analisis y reconstruccion del decaimiento hadronico J/psi meson va kaon(+)kaon(-)pion(+)pion(-)pion(0).

摘要

The Branching Ratio of production for the hadronic decay J/psi→ K+K-pi+pi -pi0 was determined and a comparison was made with previously obtained values for a sample of 3 million events of psi(2 S) for the exclusive mode psi(2S) → J/psi→ K+K -pi+pi-pi0, finding that the precision of this measurement improved.;The current analysis is based on a sample of 24.45 million events of psi(2 S registered by the CLEO-c detector, corresponding to dataset 42. In addition, we present the analysis corresponding to the associated states J/psi → eta&phis; and J/psi → o K+K- the value for their branching ratio.
