Search for exotic resonances in k- d interactions at 3 gev/c

The SABRE collaboration Giacomelli, G. ; Lugaresi-Serra, P. ; Minguzzi-Ranzi, A. ; et al.
Phys.Lett.B 33 (1970) 373-376, 1970.
Inspire Record 63055 DOI 10.17182/hepdata.28726

A systematic search for exotic states produced in K − d interactions at 3 GeV/ c is reported. From the analysis of the mass spectra of strange mesons, non-strange mesons, hyperons with S = −1 and S = −2, upper limits for the production cross sections of exotic resonances may be placed at one or two orders of magnitude smaller than for the production of normal resonances of same strangeness and baryon number.

Further search for quarks at the 70 gev ihep accelerator

Antipov, Yu.M. ; Bolotov, V.N. ; Devishev, M.I. ; et al.
Phys.Lett.B 30 (1969) 576-580, 1969.
Inspire Record 63242 DOI 10.17182/hepdata.28870

The results of the experiment searching for quarks with charge − 1 3 and 2 3 produced by 70 GeV protons on an aluminium target at zero angle are reported. For the selection of quarks the system of spectrometric scintillation counters, time-of-flight spectrometer, gas Cerenkov threshold counter and magnetic spectrometer with spark chambers were used. In the range of masses available at the IHEP accelerator, quarks were not found. The upper limit estimation of the differential cross-section for quark production with mass ⩽ 5 GeV /c 2− and charge −1 3 is 7×10 −38 cm 2 / ster GeV /c (with 90% confidence level). The total cross-section for quark production with charge −1 3 and mass 4.5–5 GeV /c 2 does not exceed 3×10 −39 cm 2 .

On the separation of single and double scattering in proton-deuteron collisions at 19.2 gev/c

Allaby, J.V. ; Diddens, A.N. ; Glauber, R.J. ; et al.
Phys.Lett.B 30 (1969) 549-554, 1969.
Inspire Record 63236 DOI 10.17182/hepdata.28891

Experimental data exhibiting the separation of single and double quasi-elastic scattering in proton-deuteron collisions at 19.2 GeV/ c and for momentum transfers around 1 GeV/ c are presented. An analysis of the scattering cross section in terms of the multiple scattering theory is given. The possibilities for the deduction of proton-neutron differential cross sections particularly at large momentum transfers are pointed out.

Charge exchange and production of eta mesons and multiple neutral pions in pi- p reactions between 654 and 1247 mev/c

Bulos, F. ; Lanou, R.E. ; Piper, A.E. ; et al.
Phys.Rev. 187 (1969) 1827-1844, 1969.
Inspire Record 62084 DOI 10.17182/hepdata.5293

An experiment designed to study the π−p total neutral cross section and its breakdown into several channels has been performed at eleven incident pion momenta ranging from 654 to 1247 MeV/c. Angular distributions for the charge exchange π0 and for η0 production are given in terms of Legendre-polynomial expansion coefficients. Forward and backward differential cross sections are presented for the charge-exchange channel and comparisons with recent dispersion-relation predictions for the forward cross section are made.

Differential cross-sections for the reactions $p + p \to D + \pi^+$ and $p + p \to D + \rho^+$ at 21-GeV/c

Phys.Lett.B 29 (1969) 198-202, 1969.
Inspire Record 56770 DOI 10.17182/hepdata.28992

Results are presented from an experiment in which high-energy deuterons, produced by proton-proton interactions at 21.1 GeV/ c incident momentum, were detected over a range of angles from 12.5 mrad to 60 mrad in the laboratory system. From the momentum spectra of the deuterons, the final states D + π + and D + ϱ + have been identified. The angular distribution for these reactions are presented and compared with previous data at lower energies.

Proton-Proton Scattering at 1.48 BeV

Eisner, A.M. ; Hart, E.L. ; Louttit, R.I. ; et al.
Phys.Rev. 138 (1965) B670-B677, 1965.
Inspire Record 944962 DOI 10.17182/hepdata.461

A sample of 2657 proton-proton scattering events at 1.48 BeV has been analyzed. The elastic cross section is 19.86 mb, and the elastic scattering is consistent with a simple opaque-disk optical model with R=0.91 F and 1−a=0.864. The dominant feature of the inelastic scattering is the production of the (3/2, 3/2) isobar. The reaction p+p→p+n+π+ is interpreted satisfactorily in terms of the one-pion-exchange model.
