Beschreibungen/Notizen

• The branching fractions of the Υ ( 1S ) inclusive decays into final states with a J / ψ or a ψ ( 2S ) are measured with higher precision to be B ( Υ ( 1S ) → J / ψ+anything ) = ( 5.25±0.13 ( stat ) ±0.25 ( syst ) ) ×10-4 and B ( Υ ( 1S ) → ψ ( 2S ) +anything ) = ( 1.23±0.17 ( stat ) ±0.11 ( syst ) ) ×10-4 . The first search for Υ ( 1S ) decays into XYZ states that decay into a J / ψ or a ψ ( 2S ) plus one or two charged tracks yields no significant signals for XYZ states in any of the examined decay modes, and upper limits on their production rates in Υ ( 1S ) inclusive decays are determined.
