A partial wave analysis of theK\(\bar K\) system produced by 8.25 GeV/cK− mesons in the reaction\(K^ -p \to K\bar K\Lambda ^{ 0} \) has been performed, taking into account the information provided by the Λ0 decay. Thef′ region is dominated byD0(−) andD1(+) waves. We see no evidence for the production of new 0++ states in the mass region 1.05 to 1.75 GeV.

DIFFERENCES BETWEEN ANTI-P P AND P P INTERACTIONS AT 8.8-GeV/c AND THEIR RELATIONSHIP TO ANTI-P P ANNIHILATIONS

We report on an experiment in which the SLAC 40-in. hybrid facility was exposed to an 8.8-GeV/c antiproton beam. Using external detectors we have identified a large fraction of nonannihilation events and thus obtained a clean sample of annihilation data. Using proton interactions taken in the same detector at the same energy we have made a detailed study of (p¯p−pp) differences and explored their relationship to p¯p annihilations.

High-Energy Quasielastic $\nu_{\mu} n \to \mu^- p$ Scattering in Deuterium

We have studied the quasielastic reaction νμn→μ−p in an exposure of the Fermilab deuterium-filled 15-foot bubble chamber to a high-energy wide-band neutrino beam. From an analysis of the Q2 distribution based on the standard V−A theory, the axial-vector mass in a dipole parametrization of the axial-vector form factor is determined to be MA=1.05−0.16+0.12 GeV, consistent with the values previously reported from low-energy experiments.

Differential cross sections for π − p and pp elastic scattering have been measured at incident momenta ranging from 30 to 345 GeV and in the t range 0.002 (GeV/ c ) 2 ⩽ | t | ⩽ 0.04 (GeV/ c ) 2 . From the analysis of the data, the ratio ϱ ( t = 0) of the real to the imaginary parts of the forward scattering amplitude was determined together with the logarithmic slope b of the diffraction cone.

In a high statistics (180 events/μb) bubble chamber study of the reaction fx K − p → K 0 π − p at 8.25 GeV c , we observe a K 0 π − state at 2088±20 MeV with a width 170 +100 −50 MeV, produced with a cross section of 3.6±1.2 μ b. In addition we observe this state in the channels K ∗ (890)ππ , ϱ K π , ω K π with a combined cross section of 7.1±2.6 μ b, and possibly K ∗ (890)πππ .

A PARTIAL WAVE ANALYSIS OF THE K PI PI SYSTEM PRODUCED IN THE REACTION K- P ---> ANTI-K0 PI+ PI- N AT 8.25-GeV/c

A partial-wave analysis of the K 0 π + π − system from the reaction K − p → K 0 π + π − n has been carried out using data obtained at 8.25 GeV/ c in a high-statistics experiment. A strong signal appears in the 1 + SO + (K ∗ π) wave at the Q 2 mass (≈ 1.4 GeV). The 1 + S0 + (ϱK) wave behaves rather like a background and does not exhibit the characteristics of a resonance. A prominent signal also appears in the 2 + D wave (via K ∗ π and ϱK); it is interpreted as the K ∗ (1430). In the L region (1.6–2.1) GeV, there is evidence for the 3 − K ∗ (1780) while the 2 − wave also gives some contribution.
