Energy dependence of the analyzing power for the p p ---> pi+ d reaction in the energy region 500-MeV - 800-MeV

Yoshida, H.Y. ; Shimizu, H. ; Ohnuma, H. ; et al.
Nucl.Phys.A 541 (1992) 443-452, 1992.
Inspire Record 320645 DOI 10.17182/hepdata.36702

The energy dependence of the analyzing power A y for the pp → π + d reaction was measured during polarized beam acceleration from 500 to 800 MeV, using an internal target inserted into the beam every acceleration cycle. The measurements were made with the pion laboratory angle fixed at 68° and with incident proton energy bins varying from 10 to 30 MeV in width. The statistical accuracy per bin is ΔA y ⋍ 0.06 .

Measurement of the Spin Correlation Parameters A(ll) and A(sl) for the Reaction $P P \to D \pi^+$ in the Energy Region 500-{MeV} - 800-{MeV}

Barlow, D.B. ; Saha, A. ; Seth, K.K. ; et al.

Angular distributions of the spin-correlation parameters Asl and All for the reaction pp→π+d have been measured at pion center-of-mass angles 40°≤θπ+*≤130° at incident energies of 500, 650, and 800 MeV. Additional measurements of All were made at 600, 700, and 750 MeV. The results of the experiment are compared with the predictions of several unified coupled-channel calculations and partial-wave analyses. While the latest partial-wave analyses were found to fit the data reasonably well, all except one of the various model predictions not only do not fit the data well, but also tend to be in disagreement with each other. The data show no clear sign of a need for proposed dibaryon resonances.

Measurements of $p p \to \pi^+ d$ between 398-MeV and 572-MeV

Aebischer, D. ; Favier, B. ; Greeniaus, L.G. ; et al.
Nucl.Phys.B 108 (1976) 214-238, 1976.
Inspire Record 114332 DOI 10.17182/hepdata.35777

The reaction pp→ π + d was studied at incident proton energies of 398, 455, 497, 530 and 572 MeV. Measurements of dσ/dΩ at 455 and 572 MeV show the presence of pion d-waves in the pion-deuteron system. Asymmetry measurements yield similar conclusions. Total cross-section measurements agree with recent fits to earlier data.

The reaction p p ---> pi+ d between 1.0 and 1.5 gev/c

Albrow, M.G. ; Andersson-Almehed, S. ; Bosnjakovic, B. ; et al.
Phys.Lett.B 34 (1971) 337-342, 1971.
Inspire Record 69312 DOI 10.17182/hepdata.28688

Polarizationdata for the reaction pp → π + d on polarized protons at 1.04, 1.13, 1.21, 1.37 and 1.45 GeV/ c are presented. The coefficient characterizing the angular distribution of the polarization show an energy dependence similar to that of the total cross-section and are consistent with the view that N ∗ ( 3 2 , 3 2 ) production dominates the reaction mechanism.
