Cross sections of common final states for K- p interactions at 8.25-GeV/c

The Athens-Democritus-Liverpool-Vienna collaboration Fry, J.R. ; Brankin, C. ; Matthews, R. ; et al.
Nucl.Phys.B 58 (1973) 408-419, 1973.
Inspire Record 83983 DOI 10.17182/hepdata.8005

Topological and channel cross sections are given for the more common final states produced in K − p interactions at 8.25 GeV/ c together with the single particle inclusive cross sections. We present cross sections for prominent resonances occurring in final states K N (nπ) and find the resonance fractions to be roughly independent of multiplicity.

Observation of increasing charged multiplicity as a function of transverse momentum in 28.5-gev/c p p interactions

Ramanauskas, A. ; Anderson, E.W. ; Fisher, G.P. ; et al.
Phys.Rev.Lett. 31 (1973) 1371-1374, 1973.
Inspire Record 83758 DOI 10.17182/hepdata.47029

We have measured the mean charged multiplicity n¯CH as a function of transverse momentum p⊥ of the forward proton in the reaction p+p→p+MM for five intervals of missing mass (MM) using our Multiparticle Argo Spectrometer System. We observe an increase of n¯CH for p⊥>1 GeV/c.

Measurement of the polarization parameter in n p charge-exchange scattering from 2 to 12 gev/c

Abolins, M.A. ; Lin, M.T. ; Ruchti, R.C. ; et al.
Phys.Rev.Lett. 30 (1973) 1183-1185, 1973.
Inspire Record 84508 DOI 10.17182/hepdata.21408

We have measured the polarization parameter in neuton-proton charge-exchange scattering for incident neutron momenta of 2-12 GeVc and 0.01<~|t|<~1.0 (GeVc)2. Results based on 300 000 events show a negative polarization whose magnitude increases monotonically with |t| approaching 60% for |t|∼0.6 and which has little energy dependence.

Measurement of elastic proton proton scattering in pure initial-spin states

O' Fallon, J.R. ; Parker, E.F. ; Ratner, L.G. ; et al.
Phys.Rev.Lett. 32 (1974) 77-79, 1974.
Inspire Record 94699 DOI 10.17182/hepdata.21307

An experiment was done using an accelerated polarized proton beam and a polarized proton target. The elastic cross section for proton-proton scattering at 6.0 GeV/c and P⊥2=0.5−1.6 (GeV/c)2 was measured in the spin states ↑ ↑, ↓ ↓, and ↑ ↓ perpendicular to the scattering plane. The cross sections were found to be unequal by up to a factor of 2.

Strange-particle production in n p interactions at 4-8 gev/c

Ansorge, R.E. ; Carter, J.R. ; Charlesworth, J.A. ; et al.
Phys.Rev.D 10 (1974) 32-44, 1974.
Inspire Record 95568 DOI 10.17182/hepdata.25044

Results of a survey of strange-particle production in np interactions in the momentum range 4-8 GeV/c are presented. As details of 3-body events have already been published, the results for the most part concern 4- and 5-body events with no missing neutrals. Cross sections for production of the most prominent resonances are given, and the properties of certain quasi-3-body channels discussed and compared with the corresponding states produced in pp interactions. It is found that the Σ−(1385) resonance is produced very strongly in unfitted topologies and certain statistical tensors for its production are shown to be in agreement with the predictions of the quark model.

We have measured elastic pion-proton scattering in a 50 GeV/ c π − beam at the 76 GeV proton synchrotron in Serpukhov. Data are presented for four-momenta transfer squared in the range 0.03 < t < 0.4 (GeV/ c ) 2 .

A Study of K+ pi- Elastic Scattering in the Reaction K+ n --> K+ pi- p Between 2.0-GeV/c and 3.0-GeV/c

Baker, S.L. ; Banerjee, S. ; Campbell, J.R. ; et al.
Nucl.Phys.B 99 (1975) 211, 1975.
Inspire Record 655 DOI 10.17182/hepdata.31833

Results are given from a study of 15 518 events of the reaction K + d → K + π − pp. The K + π − spin density matrix and the constraints imposed on it by positivity have been studied. Analyses of K + π − → K + π − elastic scattering have been carried out using methods developed by Estabrooks and Martin and Ochs and Wagner for the analogous case of ππ scattering. Results are found to be in agreement with earlier K π scattering studies using the reaction K + p → K + π − Δ ++ at much higher energies. The S-wave scattering length is found to be in agreement with the prediction of current algebra.

Differential cross-sections for the photoproduction of eta mesons from protons near 2 gev

Booth, P.S.L. ; Carroll, L.J. ; Holt, J.R. ; et al.
Nucl.Phys.B 71 (1974) 211-216, 1974.
Inspire Record 94714 DOI 10.17182/hepdata.32321

Differential cross sections for the process γ p → p η have been measuredd at c.m. angles of 28°, 35° and 42° at incident energies between 2 GeV and 2.8 GeV. Data from an earlier experiment below 2 GeV have been re-analysed and corrected. The whole set of data is compared with the form ( s − M 2 ) 2 d σ /d t , which fits data at higher energies. There is good agreement above 2 GeV, particularly at the largest angle, but strong departures below.
