The absolute cross sections for the production of 11 C by 1.59 GeV and 4.19 GeV α-particles incident on natural carbon have been measured to be 46.4 ± 1.3 mb and 42.5 ± 1.1 mb respectively. These results, together with data reported at other energies, indicate that the C(α, X) 11 C cross section becomes approximately constant at a value of about 43 mb for energies above 3 GeV (750 MeV/n). A similar energy dependence is exhibited by the C(p, X) 11 C reaction whose cross section has been measured previously over an extensive energy range. The C(α, X) 11 C cross sections are found to be in good agreement with predictions of a semi-empirical model developed to describe nuclear fragmentation.

Correlations Between High Momentum Secondaries in $p p$ Collisions at $\sqrt{s}=44$.7-{GeV} and 62.3-{GeV}

In pp collisions at √ s = 44.7 and 62.3 GeV, where each proton fragments into at least one low- p T, high- x meson or baryon, no correlations between the particle momenta are found for ππ , π K, KK, and p π pairs. The ππ data show a preference for the formation of electrically neutral ππ systems. The KK data show the influence of strangeness conservation. For pp and pΛ final states, the momentum dependence of the correlation ratio R can be described by the scaling variable z = (1 − x 1 )(1 − x 2 ). Small deviations from factorization are discussed.

The measurement of the nonelectromagnetic forward-backward charge asymmetry in the reaction e+e−→μ+μ− at s∼34.6 GeV and in the angular region 0<|cosθ|<0.8 is reported. With a systematic error less than 1%, we observe an asymmetry of (-8.1±2.1)%. This is in agreement with the standard electroweak theory prediction of (-7.6±0.6)%. The weak-current coupling constants are also reported.
