Angular dependence of p p spin correlation and rescattering observables between 1.80-GeV and 2.10-GeV.

Allgower, C.E. ; Ball, J. ; Barabash, L.S. ; et al.

Inspire Record 465999 DOI 10.17182/hepdata.43398

A polarized proton beam extracted from SATURNE II and the Saclay polarized proton target were used to determine the spin correlation parameter Aoosk and the rescattering observablesKos″ so; Dos″ok, Nos″sn, andNonsk at 1.80 and 2.10 GeV. The beam polarization was oriented perpendicular to the beam direction in the horizontal scattering plane and the target polarization was directed either along the vertical axis or longitudinally. Left-right and up-down asymmetries in the second scattering were measured. A check for the beam optimization with the beam and target polarizations oriented vertically provided other observables, of which results forDonon andKonno at 1.80, 1.85, 2.04, and 2.10 GeV are listed here. The new data at 2.10 GeV suggest a smooth energy dependence of spin triplet scattering amplitudes at fixed angles in the vicinity of this energy.

Study of Phi and f2'(1525) meson production in anti-p p annihilation at rest.

The OBELIX collaboration Alberico, A. ; Bertin, A. ; Bruschi, M. ; et al.
Phys.Lett.B 438 (1998) 430-440, 1998.
Inspire Record 481232 DOI 10.17182/hepdata.28160

The reaction p ̄ p→K + K − π 0 was analysed for antiproton annihilations at rest at three hydrogen target densities. A strong dependence of the p ̄ p→φπ 0 yield on the quantum numbers of the initial state is observed. The branching ratio of the φπ 0 channel from the 3 S 1 initial state is more than 15 times larger than the one from the 1 P 1 state. A large apparent violation of the OZI rule for tensor meson production from p ̄ p -annihilations from the P -waves (1 ++ +2 ++ ) is observed: R exp ( f ′ 2 π 0 / f 2 π 0 )=(149±20)·10 −3 , significantly exceeding the OZI-rule prediction R =16·10 −3 .
