Measurements of anti-deuteron absorption and stripping cross sections at the momentum 13.3 gev/c

Denisov, S.P. ; Donskov, S.V. ; Gorin, Yu.P. ; et al.

The absorption cross sections of antideuterons with the momentum P = 13.3 GeV/ c by Li, C, Al, Cu and Pb nuclei have been measured. Antiproton stripping of antideuterons has been registered and its cross section for C, Al and Cu has been defined. The binding energy of antideuteron is found to be ε d = 2.4 ± 0.6 MeV by measuring the angular distribution of antiprotons from stripping.

Using the colliding beam machine, VEPP-2, the excitation curve of the ø-meson resonance was investigated in the three main decay modes. The resonance parameters obtained are the width, the total cross-section and the branching ratios. Namely: Γ = (4.67 ± 0.42) Mev B ( K + K − ) = (54.0 ± 3,4) % σ o = (3.96 ± 0.35) μB B ( K o s K O L ) = (25.7 ±3,0) % B ( e + e − = (2,81 ± 0.25) × 10 −4 B ( π + π − π o ) = (20.3 ± 4,2) %

Positive pion - proton elastic scattering at 895-MeV/c, 945-MeV c, 995-MeV/c, and 1040-MeV/c

Baker, S.L. ; Dornan, P.J. ; Gopal, G.P. ; et al.
Nucl.Phys.B 18 (1970) 29-44, 1970.
Inspire Record 63038 DOI 10.17182/hepdata.7920

The differential cross section for π + p elastic scattering at 895, 945, 995 and 1040 MeV/ c has been measured in a hydrogen bubble chamber. The results are in good agreement with previous measurements using counter techniques except at extreme backward angles where significantly lower cross sections are obtained.

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 .
