Coherent $K$(s) Regeneration on Protons From 30-{GeV}/$c$ to 130-{GeV}/$c$

Bock, G.J. ; Aronson, S.H. ; Freudenreich, K. ; et al.
Phys.Rev.Lett. 42 (1979) 350, 1979.
Inspire Record 7461 DOI 10.17182/hepdata.20779

Precise measurements att=0 of the KLp→KSp amplitude (modulus and phase) were made. Over 50000 Kπ2 decays along with normalizing Kμ3 events were detected behind a 7.2-m-long liquid-hydrogen regenerator. The momentum dependence of the modulus and phase are presented, and the results are combined with those of other experiments to extract the relevant parameters of ω exchange.

Coherent Regeneration of $K_s$'s by Carbon as a Test of Regge Pole Exchange Theory

Roehrig, J. ; Gsponer, A. ; Molzon, W.R. ; et al.
Phys.Rev.Lett. 38 (1977) 1116, 1977.
Inspire Record 5134 DOI 10.17182/hepdata.21018

A measurement of the coherent regeneration amplitude in carbon in the energy range 30-130 GeV is presented. The results are consistent with the dominance of this process by ω exchange, and a precise value of the intercept of the ω trajectory is obtained: αω(0)=0.390±0.014.

Study of Hypercharge Exchange Reactions of the Type K- p --> 1- 3/2+- at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Aguilar-Benitez, M. ; Barreiro, F. ; Hemingway, R.J. ; et al.
Nucl.Phys.B 124 (1977) 189-228, 1977.
Inspire Record 101289 DOI 10.17182/hepdata.50024

Results are presented for the quasi two-body hypercharge exchange reactions of the type using data from a high statistics bubble chamber experiment. Total and differential cross sections and the momentum transfer dependence of the meson and hyperon resonance single density matrix elements are discussed. Amplitude analyses are performed for the first two reactions. The results are compared with quark model and duality predictions and with those from other related reactions.
