The energy spectra of deuterons recoiling from a deuterium gas target bombarded by transversely polarized 796-MeV protons have been measured to obtain the differential cross sections, dσdt, and analyzing powers, Ay(t), for p→-d elastic scattering over a range of laboratory angles from 4.53° to 13.02°, corresponding to a range of four-momentum transfer squared, |t|, from 0.013 to 0.108 GeV2/c2. Employing several sets of nucleon-nucleon, N-N, amplitudes obtained from N-N phase shift analyses, comparisons are made between the experimental data and the predictions of a multiple scattering theory. In this region of four-momentum transfer, Ay is shown to depend almost entirely on the spin-independent and spin-orbit N-N amplitudes. NUCLEAR REACTIONS d(p→, p)d, E=796 MeV; measured dσdt(θ) and Ay(θ); comparison with multiple-scattering theory using free N-N amplitudes, −t=0.013−0.108 GeV2/c2, Δt=1.88×10−3 GeV2/c2.

Evidence for Local Compensation of Baryon Number in $e^+ e^-$ Annihilation

We have studied at CM energies of 14, 22 and 30–36.7 GeV e + e − annihilation events in which the hadronic final state contains both a proton and an antiproton in the momentum range 1.0 < p < GeV/ c . We find that such pairs are produced predominantly in the same jet and conclude that baryon-antibaryon production is dominated by a mechanism involving local compensation of baryon number.

SMALL ANGLE CORRELATIONS OF IDENTICAL PARTICLES IN CARBON CARBON INTERACTIONS AT P = 4.2-GEV/C PER NUCLEON

Inspire Record 200208 DOI 10.17182/hepdata.39586

Two-particle small-angle correlations between negative pions and between protons in carbon-carbon collisions atP=4.2 GeV/c per nucleon have been studied, both for an unbiased sample and for “central” events. A comparison of experimental π− π− andpp correlation functions with theoretical predictions has been made. A possible evidence for the existence of two fireballs in C+C interactions atP=4.2 GeV/c per nucleon is presented.

ELECTROPRODUCTION OF ETA MESONS IN THE REGION OF THE RESONANCE S11 (1535) AT MOMENTUM TRANSFERS OF 2-GEV**2 AND 3-GEV**2

We report on results of η-electroproduction in the resonance region at momentum transfers ofQ2=2 GeV2 and 3 GeV2. The differential cross sections obtained in the region of the second nucleon resonance strongly support the dominance of theS11(1535) in this channel. The total transverse virtual photoproduction cross section of theS11(1535) shows a flatQ2-dependence ∼e−0.39·Q2. Comparison with the total resonant γvp cross section in the second resonance region aroundW=1.5 GeV shows that theD13(1520) production decreases much faster (∼e−1.6·Q2). The data are not compatible with the simple harmonic oscillator quark model with spin and orbit excitation of a quark only.
