Abstract

Measurement of the energy of neutrons in coincidence with the production of free Ξ^- hyperons can be used to determine the masses of ¹²_ΛΛB hypernuclear states and branching ratios of their formation from (Ξ^-, ¹²C)_atom→¹²_ΛΛB+n. The E885 Collaboration utilized the Alternating Gradient Synchrotron 1.8 GeV/c K^- beam incident on a diamond target to accumulate the largest-to-date data sample of (K^-,K⁺) events. A total of about 3 × 10⁵ (K^-,K⁺) events have been collected and analyzed. The neutron spectrum shows no apparent peaks from the neutron-emission channel of double-Λ hypernuclear formation from (Ξ^-, ¹²C)_atom decay. The upper limit on the branching ratio of the above process has been set to be at or below 4% in the region of expected neutron energies.
