KAON SCATTERING AND CHARGED SIGMA HYPERON PRODUCTION IN K- P INTERACTIONS BELOW 300-MEV/C

Ciborowski, J. ; Gwizdz, J. ; Kielczewska, D. ; et al.
J.Phys.G 8 (1982) 13-32, 1982.
Inspire Record 179889 DOI 10.17182/hepdata.38531

In an experiment on K--proton interactions in a hydrogen bubble chamber, the cross sections and angular distributions have been studied for elastic and charge-exchange scattering, and charged sigma hyperon production in the momentum range 90-300 MeV/c. Good agreement is found with previous cross sections except for the charge-exchange channel where the new values are 60% larger. The production distributions of the charged sigma hyperons and the polarisation of the Sigma + hyperon clearly indicate that P waves are present down to about 150 MeV/c, much lower than previously reported.

Additional data in the reaction pi+ p ---> sigma+ k+ at 1.28 and 1.41 gev/c and a test of charge independence in the center-of-mass energy range 1.820 to 2.090 gev

Inspire Record 67769 DOI 10.17182/hepdata.23075

Data at two additional π+ momenta (1.28 and 1.41 GeVc) in the reaction π+p→Σ+K+ are presented. Charge independence is tested over the c.m. energy range 1.820 to 2.090 GeV; we used our data for the Σ+K+ channel and published data for the π−p→Σ0K0 and Σ−K+ channels.

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.

Energy Dependence of the Reactions K0(L) p --> K0(s) p, pi+ Lambda, pi+ Sigma0 from 1540-MeV to 1610-MeV

Engler, A. ; Keyes, G. ; Kraemer, R.W. ; et al.
Phys.Lett.B 63 (1976) 231-234, 1976.
Inspire Record 3809 DOI 10.17182/hepdata.27639

The reactions K L o p→K S o p, π + Λ , π + Σ o have been measured for center-of-mass energies from 1540 to 1610 MeV. Channel cross sections and coefficients of the Legendre polynomial expansion of the differential cross sections and hyperon polarizations are presented. We see no evidence in the πΛ channel for the suggested 3 2 − resonance at 1580 MeV. The cross section for the K S o p channel shows an energy dependence which is not predicted by the existing phase shift solutions based on charged kaon data.

A Study of the Reactions K0(L) p --> Lambda pi+, Lambda pi+ pi0 and Sigma0 pi+ in the Center-Of-Mass Energy Range 1490-MeV-1700-MeV

Nucl.Phys.B 110 (1976) 1-24, 1976.
Inspire Record 108723 DOI 10.17182/hepdata.35768

K L 0 p interactions were studied in the CERN 2m H 2 bubble chamber in the c.m. energy range 1490–1700 MeV. The experimental details are described. Results are presented on the final states Λπ + , Σ 0 π + and Λπ + π 0 . The effect of these data on a recent partial-wave analysis of the two-body states is examined.

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 in the Center-Of-Mass Energy Range 1.54-GeV to 1.71-GeV

Nucl.Phys.B 132 (1978) 189-211, 1978.
Inspire Record 121297 DOI 10.17182/hepdata.35162

New experimental results on the reactions K L 0 p→K S 0 p, Λπ + , Σ 0 π + andΛπ + π 0 at c.m. energies between 1.54 and 1.71 GeV are presented. This experiment has a statistical accuracy comparable with or greater than corresponding K − p and K − d experiments in the same energy range and a comparison with the data from these different types of experiments has been made. A search has been made for narrow states with masses in the region of 1.58 GeV.

Nucl.Phys.B 90 (1975) 1-19, 1975.
Inspire Record 91427 DOI 10.17182/hepdata.32062

We present the results of a formation experiment for the reaction K − p → Λπ 0 in the cms energy between 2200 and 2436 MeV with a total statistics of 10 eV/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in the P 3 , D 5 and G 9 (or H 11 ) states in this mass region.
