$K^+$ Fragmentation and Prompt Kaon Production in $K^+ P$ Collisions at 70-{GeV}/c

De Wolf, E.A. ; Goldschmidt-Clermont, Y. ; Spyropoulou-Stassinaki, M. ; et al.
Z.Phys.C 31 (1986) 13-19, 1986.
Inspire Record 232414 DOI 10.17182/hepdata.15895

We present data on inclusive production ofK+ andKS0 mesons in a 70 GeV/cK+p experiment performed in BEBC filled withH2. Cross sections and inclusive Feynman-x distributions for identifiedK+'s andKS0's are presented. The spectra of “prompt” non-diffractiveKS0 are determined by subtraction of the decay products of prominent resonances and diffractive contributions. These data, contrary to the overall inclusive spectra, allow to differentiate between some fragmentation models for soft hadron-hadron interactions.

$K^+$ nucleon elastic scattering at 180° between 1.0 and 1.5 GeV/c incident momentum

Adams, U. ; Carter, R.S. ; Cook, V. ; et al.
Nucl.Phys.B 87 (1975) 41-51, 1975.
Inspire Record 1392682 DOI 10.17182/hepdata.32061

We have measured the cross section at 180° for K + p and K + n elastic scattering in the momentum range 1.0 to 1.5 GeV/ c . The K + n cross section was measured on deuterium and the K + p on hydrogen and deuterium. We were thus able to measure directly the difference between free nucleon (proton) scattering and bound nucleon (proton) scattering at large angles. This difference was found to be small and within our experimental accuracy the K + p(n) cross section should be equal to the K + p (free) cross section at 180°. We found no evidence for an s -channel resonance Z ∗ in either the K + p or K + n system. A comparison of our data and those of other groups with theoretical predictions is given.

Gordon, J. ;
Phys.Lett. 21 (1966) 117-120, 1966.
Inspire Record 1389617 DOI 10.17182/hepdata.29930

1691 events were fitted to K - p elastic scatters at a K - momentum of 3.46 GeV/ c . The differential cross section as a function of 4 momentum transfer was fitted to exp ( A + Bt + Ct 2 ) with A = 3.7 B = 8.7 ( GeV / c ) −2 and C = 2.0 ( GeV / c ) −4 . The distribution is consistent with zero real part for the forward scattering amplitude.

$K^- p$ and $\bar{p} p$ Elastic Scattering at 10.1-{GeV}/$c$

Berglund, A. ; Buran, T. ; Carlson, P.J. ; et al.
Nucl.Phys.B 176 (1980) 346-354, 1980.
Inspire Record 133174 DOI 10.17182/hepdata.34457

The differential cross sections for K − p and p p elastic scattering have been measured over the range of four-momentum transfer squared 0.18<− t <3.3 (GeV/ c ) 2 . The K − p data decrease smoothly as a function of − t , whereas, the p p data shows a break at − t = 0.6 (GeV/ c ) 2 followed by a fast drop to − t ≅ 1.6 (GeV/ c ) 2 where the differential cross section levels off and stays constant out to − t = 3 (GeV/ c ) 2 .

Phys.Lett.B 24 (1967) 596-598, 1967.
Inspire Record 1389623 DOI 10.17182/hepdata.29569

The differential elastic scattering cross section for 2.24 GeV/ c K − p collisions has been measured in film from the Brookhaven 20″ bubble chamber. The total elastic cross section is found to be 6.2 ± 0.7 mb. The exponential dependence on square of the momentum t in (GeV/ c ) 2 is fitted by ( d σ d Ω elastic = (12.4 ± 1.0 mb/sr) exp (7.81 ± 0.25)t . A A fit to a black disc model requires a radius of 0.95 ± 0.05 fm.

$K^- p$ total and elastic cross sections at 2.66 GeV/c

Ficenec, J.R. ; Trower, W.P. ;
Phys.Lett.B 25 (1967) 369-372, 1967.
Inspire Record 1389627 DOI 10.17182/hepdata.29435

At an incident kaon momentum of 2.66 GeV/ c we have measured the total and elastic cross sections to be 30.2 and 5.70 mb respectively. The elastic scattering angular distribution is dominated by a single diffraction peak; and when this peak is fit to an exponential in momentum transfer t , the first order term is both necessary and sufficient. This fit evaluated at t =0 is consistent with a purely imaginary forward scattering amplitude. Our data when compared with that of others indicates no shrinkage of the diffraction peak. The entire angular distribution was also fit to a Legendre series, with order 9 being required to represent the data.

Inspire Record 153341 DOI 10.17182/hepdata.27173

Inclusive K 0 -production has been measured in e + e - annihilation at a center of mass energy of about W = 30 GeV. The ratio of K 0 + K 0 production to μ + μ - production is R K 0 = 5.6 ± 1.1 (statist. error) ± 0.8 (system.error) This value is about a factor of three higher than R K 0 at W = 7 GeV. The cross sections ( s / β ) d σ /d x is consistent with a scaling behaviour.

$K^0(s$) $K \pi$ Production in Tagged and Untagged $\gamma \gamma$ Interactions

The CELLO collaboration Behrend, H.J. ; Criegee, L. ; Dainton, J.B. ; et al.
Z.Phys.C 42 (1989) 367, 1989.
Inspire Record 266414 DOI 10.17182/hepdata.15529

We have searched for resonance production in the reaction γγ→Ks0Kπ. No signal was found for theηc and an upper limit for the radiative with\(\Gamma _{\gamma \gamma }^{\eta _c } \) keV (95% c.l.) is obtained. For the glueball candidate η(1440) (previouslyi) the upper limit\(\Gamma _{\gamma \gamma }^{\eta (1440)} B(\eta (1440) \to K\bar K\pi )< 1.2keV(95\% c.l.)\) is derived. In the tagged data sample resonance formation of a spin 1 state at 1420 MeV is observed, which is absent in the untagged data. The mass and width of this state are consistent with those of thef1(1420); an analysis of decay angular distributions favours positive parity.
