We report on inclusive K0 production in the region of the upsilon resonances (9.4–10.6 GeV). The K0 yield for the resonances and continuum below the BB threshold is found to be constant at 0.82 ± 0.10 K0 per observed hadronic event. At the ϒ(4S), however, the K0 yield is significantly higher, 1.58 ± 0.35. This increase in K0 production and the differential cross section dσ/dp of kaons are consistent with BB decay of the ϒ(4S) resonance with the bottom quarks subsequently decaying primarily into charmed quarks.

Abstract We have searched for an almost stable, charged particle produced in 400 GeV proton-nucleus collisions. A total of 5 × 10 10 light secondary particles were sampled in a secondary beam of 70 GeV/ c momentum. If a 4.5 to 6.0 GeV mass particle is produced with a cross section comparable with the production cross section of the upsilon then this experiment places an upper limit on the lifetime of such a particle of about 5 × 10 −8 s.

A new type of hadron calorimeter is described which measures the energy of ahadronby detecting the Cherenkov light produced by the hadronic shower it initiates in a large tank of water. The device features large aperture with good uniformity, good energy containment, andmodest resolution at modest cost. The response was studied as a function of particle type and momentum. Resolution of 40% (RMS) has been achieved at 20 GeV.
