We present tables of the absolute differential cross sections of elastic pd scattering. The cross-section data have been obtained at the Serpukhov accelerator from 10 to 70 GeV in the | t |-range 0.002–0.2 GeV 2 / c 2 .

The charge exchange anti-p p ---> anti-n n at 5.0 and 7.76 gev/c near the forward direction

Lee, J.G. ; Harckham, A. ; Letheren, M. ; et al.
Nucl.Phys.B 52 (1973) 292-300, 1973.
Inspire Record 84235 DOI 10.17182/hepdata.32683

The differential cross section for the charge exchange p p → n n has been measured with high statistics at 7.76 GeV/ c and at 5.0 GeV/ c . The 7.76 GeV/ c data show a very narrow [ Δt ⪅ 0.01 (GeV/ c ) 2 ] forward peak superposed on a slow exponential fall-off.

Elastic anti-proton-deuteron scattering below 1.0 gev/c

Inspire Record 84236 DOI 10.17182/hepdata.32679

We present differential cross sections for elastic p d scattering at beam momenta 0.735 and 0.940 GeV/ c and momentum transfers in the range 0.04<| t |<0.5(GeV/ c ) 2 . The p d elastic differential cross section is expressed in terms of a deutron form factor and the I =0 t -channel exchange N N amplitudes, enabling us to isolate the corresponding I =0 t -channel exchange cross sections.

The p p and p n elastic differential cross sections have been extracted from the reaction p d→ p pn in which the deuteron breaks up. The incident antiproton momenta were 0.480, 0.735 and 0.940 GeV/ c , and the range of the momentum transfers was 0.04 < ∣ t ∣ < 0.7 (GeV/ c ) 2 . Both p p and p n differential cross sections are diffraction-like, with structure similar to the higher-momentum data.

Observation of the *forbidden* double charge exchange reaction anti-p p ---> antisigma- sigma- at 3.6 gev/c

Atherton, H.W. ; Celnikier, L.M. ; French, B.R. ; et al.
Phys.Lett.B 42 (1972) 522-526, 1972.
Inspire Record 84969 DOI 10.17182/hepdata.28179

Data are presented which firmly establish the existence of the double charge exchange reaction p p → Σ − Σ − at 3.6 GeV/ c . The forward cross section was found to be (5.9 ± 1.1) μb and the ratio of the “forbidden” to “allowed” forward cross section is R = σ( Σ − Σ − σ( Σ + Σ + ) = 0.09 ± 0.02 .

Charged particle productions at 90 degrees in the center-of-mass in very high energy proton proton collisions

Banner, M. ; Hamel, J.L. ; Pansart, J.P. ; et al.
Phys.Lett.B 41 (1972) 547-551, 1972.
Inspire Record 85071 DOI 10.17182/hepdata.28219

The transverse momentum distribution at 90° of pions, protons and antiprotons have been measured at the CERN intersecting storage rings for C.M. energies between 23.2 and 52.7 GeV. In this energy range, the pion and proton distributions are almost energy independent. The antiproton production rises by a factor of two between 23.2 and 52.7 GeV.

Production and decay properties of the B-meson are studied in the reactions π±p→B±p at 11 GeV/c. Values for mass, width, total and differential cross-sections and spin density matrix elements are given. The spin and parity, and the helicity states in the B→πω decay, are analysed.

Inspire Record 87004 DOI 10.17182/hepdata.37784

A sample of 43000 two-prong events obtained at a momomentum of 11.7 GeV/c is used to determine the cross-sections of the fitted channels, and to study the reaction π+p→π+pπ0. We investigate in particular the quasi-two-body channels π0Δ++ and ρ+p.

Characteristics of the Reaction $pp \to p + X$ at 205 GeV/c.

Phys.Rev.Lett. 31 (1973) 1080-1083, 1973.
Inspire Record 81790 DOI 10.17182/hepdata.21407

The inelastic reaction p+p→p+X is studied at 205 GeV/c. The distribution of the square of the missing mass, M2, shows a large diffractivelike peak at low M2 due to two-, four-, and six-prong events. The slope of the invariant cross section versus t decreases with increasing M2. The energy dependences of the multiplicity moments for the recoiling system X are similar to those for corresponding moments for p+p→(n chargedparticles).
