A Study of the Reactions $K^0_L p \to K^0_S p$, $\Lambda \pi^+$, $\Sigma^0 \pi^+$ and $\Lambda \pi^+ \pi^0$ Near 550-{MeV}/$c$

Engler, A. ; Keyes, G. ; Kraemer, R.W. ; et al.

Phys.Rev.D 18 (1978) 3061, 1978.

Inspire Record 6591 DOI 10.17182/hepdata.24324

We present measurements of the differential and polarization cross sections for the reactions KL0p→Ks0p, Λπ+, Σ0π+, and Λπ+π0 made in a hydrogen bubble chamber exposed to a beam of KL0 with incident momentum 550±35 MeV/c. The quasielastic data imposes additional constraints on the partial-wave analyses of the KN and K¯N systems. Our data show no strong energy-dependent effects in the region of the reported Σ(1580), JP=32− state. The phase of the forward regeneration amplitude was found to be about - 160° independent of KL0 momentum.

K0(L) p Interactions at 550-MeV/c

Cho, Y. ; Derrick, M. ; Miller, R.J. ; et al.

Phys.Lett.B 60 (1976) 293-296, 1976.

Inspire Record 2899 DOI 10.17182/hepdata.27718

Differential and channel cross sections and hyperon polarizations are presented for the reactions K L o p → K S o p, π + Λ o , and π + Σ o at an average beam momentum of 550 MeV/ c . These data provide constraints on KN and K N amplitudes obtained from charged kaon reactions and reject one of the S = +1, I = 0 and one of the S = -1, I = 1 phase shift solutions.

A Search for Delta I = 2 Electromagnetic Currents in Pion Photoproduction

Inspire Record 90951 DOI 10.17182/hepdata.21245

Differential cross sections for the reactions γp→π0p, π+n and γn→π−p, π0n were measured in a single experiment using tagged photons in the energy region 240-450 MeV incident on H21 and H22 targets. Results of the measurements of the ratios π0nπ0p and π−pπ+n are presented. The ratio of isotensor to isovector amplitude is found to be 0.00±0.02.

Measurements of d p backward elastic scattering at 3.43, 4.50, 5.75, and 6.60 gev/c incident deuteron momentum

Dubal, L. ; Hargrove, C.K. ; Hincks, E.P. ; et al.

Phys.Rev.D 9 (1974) 597-603, 1974.

Inspire Record 93110 DOI 10.17182/hepdata.21938

Differential cross sections for dp elastic scattering from 60° to 175° center of momentum (c.m.) were measured at 3.43, 4.50, 5.75, and 6.60 GeVc incident deuteron momentum. The measurements were made with a two-arm magnetic spectrometer, making use of multiwire proportional chamber detectors. The deuterons were accelerated at the Bevatron of the Lawrence Berkeley Laboratory. Data are compared with predictions of the baryon-pickup model and the one-pion-exchange model. The backward dip at 180° c.m. for 4.5 GeVc, predicted by Craigie and Wilkin using the one-pion-exchange model, is not observed, but reasonable fits to the momentum variation and angular distributions are found. When the data are plotted against the variable Δ of the baryon-pickup model, the s dependence is greatly reduced.
