We discuss how the spatial intermittency of energy dissipation in 3D fully developed turbulence affects the small-scale statistics of passive scalars. We relate the passive-scalar behaviour to the diffusion properties of particle pairs in turbulent fluids. We thus find the intermittency correction to the -5/3 Obukhov-Corrsin law for the power spectrum of a passive scalar at wavenumber k where molecular diffusion and viscosity play a negligible role (inertial convective subrange). This correction is positive at difference with the negative correction to the -5/3 Kolmogorov law for the energy spectrum. We finally show that the structure functions of passive scalars have scaling exponents linear in the moment order, even in the framework of multifractal models.

The ratio of the real to the imaginary part of the pp forward elastic-scattering amplitude ϱ has been measured at 550, 757, and 1077 MeV/ c at LEAR, using the Coulomb-nuclear interference method. The results obtained for ρ and b , the nuclear slope, are ϱ = 0.084 ± 0.051 and b = 20.9 ± 2.1 (GeV/ c ) −2 at 550 MeV/ c , ϱ = 0.102 ± 0.043 and b = 18.0 ± 0.5 (GeV/ c ) −2 = at 757 MeV/ c , and ϱ = 0.059 ± 0.035 and b = 15.2 ± 0.3 (GeV/ c ) −2 at 1077 MeV/ c .

Measurements have been made of the differential cross section and asymmetry A on for p p elastic scattering at 15 incident momenta between 497 MeV/ c and 1550 MeV/ c . The angular range where both particles have enough energy to traverse target and setup has been covered. The results are compared with predictions of various N N potential models. None of these models fully explains the present results, although the general trend of the data is predicted correctly.

We discuss a measurement of the differential cross section for the reaction KLp→KSp for incident momenta between 5 and 10 GeV/c and the |t| region 0.025 to 0.5 (GeV/c)2, carried out using the SLAC 15-in. rapid-cycling hydrogen bubble chamber triggered by the K0 spectrometer facility. This hybrid detector allowed measurement of the KL beam momentum, measurement of the recoil-proton momentum, and measurement of the decay position and momentum of the KS. Over this momentum region the ratio of the real to imaginary part of the forward-scattering amplitude was determined to be 0.93±0.24 and the phase of the forward-scattering amplitude was determined to be -(138±7)°. A fit to the forward differential cross section of the form dσdt∝p2α(t)−2 to our data together with previous measurements of the KLp→KSp differential cross section at this and lower momenta yielded an α(0)=0.39±0.10 for the dominant ω Regge trajectory. The value of α(0) as determined from the phase φ=−π[α(0)+1]2 is 0.54±0.11.
