We report on an experiment to obtain differential cross sections for K+p elastic scattering in the vicinity of the possible exotic baryon, the Z1*(1900). The differential cross sections are based on typically 70 000 selected events in the angular region −0.9≤cosθc.m.≤0.9 at each of 22 momenta from 0.865 to 2.125 GeV/c. The data are intended for use in partial-wave analysis to search for the Z1*.

Measurement of the real part of the k- p elastic scattering amplitude at 10 gev/c

Campbell, J.R. ; Cocconi, V.T. ; Duinker, P. ; et al.
Nucl.Phys.B 64 (1973) 1-13, 1973.
Inspire Record 94948 DOI 10.17182/hepdata.32421

Bubble chamber film of 10 GeV/ c K − p interactions was scanned automatically by an H.P.D. to look for small angle scatters in the | t |-range from 0.008 to 0.1 GeV 2 . Combining the 1800 events so obtained with 22 000 elastic events obtained from normal scanning (| t | > 0.06 GeV 2 ), the real part of the elastic scattering amplitude was found to be (+25 ± 10)% of the imaginary part. Evidence is found for a change in slope in the differential cross-section distribution, from 9.8 ± 0.6 GeV −2 in the | t |-range below 0.1 GeV 2 to 7.1 ± 0.2 GeV −2 in the range 0.12 < | t | ⩽ 0.4 GeV 2 .

K-plus p elastic scattering at 864, 969 and 1207 mev/c

Bland, R.W. ; Goldhaber, G. ; Trilling, G.H. ;

Inspire Record 56713 DOI 10.17182/hepdata.28975

The differential cross section for K + p elastic scattering has been measured at 864, 969 and 1207 MeV/ c . Our data show a smooth transition from low-energy s-wave scattering to high-energy diffraction, and are some-what in disagreement with a recent experiment on K + p backward scattering.

On Measuring Spin Rotation Parameter r in pi- p and K- p Elastic Scattering at 40-GeV/c

The Serpukhov-Saclay-Dubna-Moscow collaboration Pierrard, J. ; Bruneton, C. ; Bystricky, J. ; et al.
Phys.Lett.B 57 (1975) 393-397, 1975.
Inspire Record 99593 DOI 10.17182/hepdata.27839

The spin rotation parameter R has been measured for elastic π − p scattering at 40 GeV/ c , at four momentum transfers t ranging from −0.19 to −0.52 (GeV/ c ) 2 . The average value within this interval is R π − p = -0.200± 0.023. The resulting constraints on the πN scattering amplitudes are discussed. The experiments also yields an average value for K − p scattering, R K − p scattering, R K − p = -0.16±0.16.

The angular distributions of K + p and π + p backward elastic scattering have been measured at 5.2 and 6.9 GeV/ c . Backward π - p and K - p elastic scattering were studied at 6.9 GeV/ c . Backward peaks are observed in K + p scattering with an energy dependence of the form s −4 .

Elastic Scattering of 10-GeV/c pi+ and K+ Mesons and of 9-GeV/c Protons on Protons

Baglin, C. ; Briandet, P. ; Fleury, P. ; et al.
Nucl.Phys.B 98 (1975) 365-400, 1975.
Inspire Record 98834 DOI 10.17182/hepdata.31908

Angular distributions of π + and K + p elastic scattering have been measured for an incident beam momentum of 10.0 GeV/ c . For π + p elastic scattering almost the complete angular distribution was measured. The angular distribution of proton-proton elastic scattering was measured for an incident momentum of 9.0 GeV/ c in the interval of the four-momentum transfer squared from 0.7 (GeV/ c ) 2 to 5.0 (GeV/ v ) 2 . For π + p elastic scattering the structures at − t = 2.8 (GeV/ c ) 2 and − t = 4.8 (GeV/ c ) 2 are less pronounced than at lower momenta. The cross section for scattering at 90° in the c.m. system is of the order of 1 nb/GeV/ c ) 2 . For K + p elastic scattering is a break in the angular distribution around − t = 3 (GeV/ c ) 2 . The differential cross sections for proton-proton elastic scattering decrease smoothly with increasing momentum transfers.

Large angle pi+ p and k+ p elastic scattering at 13.8 gev/c

Rubinstein, R. ; Cornillon, P. ; Grindhammer, Guenter ; et al.
Phys.Rev.Lett. 30 (1973) 1010-1012, 1973.
Inspire Record 84502 DOI 10.17182/hepdata.21417

The differential cross section for π+p elastic scattering has been measured at 13.8 GeVc for 0.7<|t|<3.8(GeVc)2. The cross section is found to be equal to that previously obtained for π−p elastic scattering, except in the region |t|=2.8 (GeVc)2, where the π+p data do not show the prominent dip observed in π−p scattering. Data have also been obtained for 13.8−GeVc K+p elastic scattering for 0.8<|t|<2.2 (GeVc)2.

K+- proton scattering from 200 to 600 MeV/c

Burnstein, R.A. ; LeFebvre, J.J. ; Petersen, D.V. ; et al.
Phys.Rev.D 10 (1974) 2767-2777, 1974.
Inspire Record 97215 DOI 10.17182/hepdata.24945

The differential cross section for K+p elastic scattering has been measured at several momenta in the interval 200-600 MeV/c within a hydrogen bubble chamber. The data have been fitted with a partial-wave analysis. We obtain solutions which are dominated over the entire momentum range by s-wave scattering, with constructive interference between the nuclear and Coulomb scattering. The effective-range approximation with only s waves yields a K+p scattering length a=−0.314±0.007 F and an effective range r0=0.36±0.007 F. The measured total inelastic cross section at 588 MeV/c is 11−5+9 μb.
