Inspire Record 181092 DOI 10.17182/hepdata.34198

The polarization parameter in pn elastic scattering has been measured at 24 GeV/ c over the range of four-momentum transfer squared 0.1 < | t | < 1.25 (GeV/ c ) 2 , and found to be negative except for a zero at | t | = 0.65 (GeV/ c ) 2 .

DECAY OF B MESONS INTO CHARGED AND NEUTRAL KAONS

The CLEO collaboration Brody, A. ; Chen, A. ; Goldberg, M. ; et al.
Phys.Rev.Lett. 48 (1982) 1070-1074, 1982.
Inspire Record 180612 DOI 10.17182/hepdata.27749

Data on inclusive kaon production in e+e− annihilations at energies in the vicinity of the ϒ(4S) resonance are presented. A clear excess of kaons is observed on the ϒ(4S) compared to the continuum. Under the assumption that the ϒ(4S) decays into BB¯, a total of 3.38±0.34±0.68 kaons per ϒ(4S) decay is found. In the context of the standard B-decay model this leads to a value for (b→c)(b→all) of 1.09±0.33±0.13.

KAON SCATTERING FROM C AND CA AT 800-MEV/C

Marlow, Daniel R. ; Barnes, P.D. ; Colella, N.J. ; et al.
Phys.Rev.C 25 (1982) 2619-2637, 1982.
Inspire Record 180999 DOI 10.17182/hepdata.26337

Results from K± elastic and inelastic scattering from C12 and Ca40 are reported. The data were all taken at an incident momentum of 800 MeV/c over an angular range from 2° to 38°. The elastic data are compared to first-order optical model calculations in coordinate and momentum space; good qualitative agreement is obtained. The inelastic data (from C12 only) are compared to distorted-wave Born approximation calculations, and good agreement is found if "realistic" inelastic transition densities are used. Although a first-order optical potential description does not describe the data fully, there are strong indications of the increased penetrability of K+ over K− in this energy range. NUCLEAR REACTIONS C12(K±,K±)C12, Ca40(K±,K±)Ca40, E=442 MeV (800 MeV/c), measured σ(θ) for elastic and inelastic scattering, compared to optical model and DWBA calculations, deduced optical potential parameters; θ=2°−38°, Δθ=1°.

INCLUSIVE K0 PRODUCTION IN E+ E- ANNIHILATION AT THE UPSILON RESONANCES

Giannini, G. ; Finocchiaro, G. ; Lee-Franzini, Juliet ; et al.
Nucl.Phys.B 206 (1982) 1-11, 1982.
Inspire Record 183794 DOI 10.17182/hepdata.28689

We report on inclusive K 0 production in the region of the upsilon resonances (9.4–10.6 GeV). The K 0 yield for the resonances and continuum below the B B threshold is found to be constant at 0.82 ± 0.10 K 0 per observed hadronic event. At the ϒ (4S), however, the K 0 yield is significantly higher, 1.58 ± 0.35. This increase in K 0 production and the differential cross section d σ /d p of kaons are consistent with B B decay of the ϒ (4S) resonance with the bottom quarks subsequently decaying primarily into charmed quarks.

Inspire Record 182836 DOI 10.17182/hepdata.30869

Using the Primakoff formalism, we have extracted the radiative decay width of the A + 2 (1310) produced in coherent interactions of 200 GeV/ c π + mesons in nuclear targets. The width obtained is 295 ± 60 keV, a value consistent with quark-model predictions.

Using the Primakoff formalism, we have extracted the radiative decay width of the K ∗+ (1430) produced in coherent interactions of 200 GeV/ c K + mesons in nuclear targets. The width obtained is 240 ± 45 keV, a value reasonably consistent with quark-model predictions.

Comparison of $p \bar{p}$ and $p p$ Interactions at $\sqrt{s}=53$-{GeV}

Results are presented from the first p p colliding beam runs at the CERN ISR, using the UA5 streamer chamber detector. p p interactions at s = 53 GeV are compared with pp data taken in the same experiment. The results are in good agreement with extrapolations of low-energy p p data.

Study of $e^+ e^- \to K^0_S K^\pm \pi^\mp$ in the 1.4-{GeV} to 2.18-{GeV} Energy Range: A New Observation of an Isoscalar Vector Meson $\phi^\prime$ (1.65-{GeV})

Mane, F. ; Bisello, D. ; Bizot, J.C. ; et al.
Phys.Lett.B 112 (1982) 178-182, 1982.
Inspire Record 176801 DOI 10.17182/hepdata.30954

First measurements of the e + e − → K S 0 K ± π ∓ reaction in the 1.4–2.18 GeV energy range have been performed with the magnetic detector DM1 at the Orsay storage rings DCI. The cross section is rather large. The production is mainly K ∗0 K 0 which reveals an interference between isovector and isoscalar amplitudes. These results show again the existence of an isoscalar vector at 1.65 GeV shown to be a φ ′ meson.

A STUDY OF THE REACTION K- P ---> K- PHI P AT 8.25-GeV/c

The BIRMINGHAM-CERN-GLASGOW-MICHIGAN STATE-PARIS collaboration Baubillier, M. ; Bloodworth, I.J. ; Burns, A. ; et al.
Nuovo Cim.A 70 (1982) 471-481, 1982.
Inspire Record 183657 DOI 10.17182/hepdata.37525

The dissociation of a K− into the K−ϕ system is studied at 8.25 GeV/c. The cross-section for K−ϕp production is (27±2) μb. All the expected properties of diffraction are found (mass spectrum, mass-slope correlation, 1+S wave dominance). There is also an indication of the Kϕ decay mode of a 2− resonance in theL region.

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.
