Inclusive Charm Cross-Sections in 800-GeV/c p p Interactions

The LEBC-MPS collaboration Ammar, R. ; Banerjee, S. ; Baland, J.F. ; et al.
Phys.Lett.B 183 (1987) 110, 1987.
Inspire Record 233423 DOI 10.17182/hepdata.42573

We report a measurement of the inclusive D/D̄ production cross section in 800 GeV/ c proton-proton interactions. The experiment used the high resolution bubble chamber LEBC exposed to an 800 GeV/ c proton beam at the Fermilab MPS. We obtain σ( D/ D ̄ )=59 −15 +22 μ b (statistical errors), having analysed 25% of the total data sample. Comparison with 400 GeV/ c pp dat a obtained with LEBC at CERN shows a D/D̄ cross section increase by a factor of 1.7 −0.5 +0.7 . This is in good agreement with fusion model calculations.

Elastic Differential Cross Sections for pi + /- + p Scattering from 2.3-6.0 BeVc

Coffin, C.T. ; Dikmen, N. ; Ettlinger, L. ; et al.
Phys.Rev. 159 (1967) 1169-1175, 1967.
Inspire Record 52242 DOI 10.17182/hepdata.26578

Elastic differential cross sections were measured at 6 energies between 2.3 and 6 BeVc for π++p and π−+p. The behavior of the secondary peak as a function of energy and charge is shown. Evidence for considerable resonance structure is seen in the angular distributions.

Characteristics of Charm Production by 400-{GeV} Protons

Duffy, M.E. ; Fanourakis, G.K. ; Loveless, R.J. ; et al.
Phys.Rev.Lett. 57 (1986) 1522, 1986.
Inspire Record 229849 DOI 10.17182/hepdata.20206

In a beam-dump experiment at Fermilab the cross section for charm-particle production has been deduced from a measurement of the prompt neutrino flux. The reaction cross section, if we assume only DD¯ and the dependence on atomic weight A0.75, is 57.2 ± 2.9 ± 8.5 μb/nucleon and the dependence on Feynman x and transverse momentum is EDd3σdpD3∝(1−x)3.2e−1.5p⊥ (p⊥ in GeV/c). The data are consistent with as much as 40% diffractive production of ΛcD¯.

Measurement of the double-charge-exchange reactions pi- p ---> k+ sigma- and k- p ---> pi+ sigma -

Akerlof, C.W. ; Caldwell, P.K. ; Coffin, C.T. ; et al.
Phys.Rev.Lett. 27 (1971) 539-542, 1971.
Inspire Record 68930 DOI 10.17182/hepdata.21463

The forward cross sections for the reactions π−p→K+Σ− and K−p→π+Σ− have been determined for incident particle momenta in the range of 2.75 to 3.50 GeV/c, and an upper limit was established at 5.00 GeV/c. These measurements show that the double-charge-exchange process π−p→K+Σ− is suppressed by a factor of 1500 at 3 GeV/c relative to the single-exchange reaction π+p→K+Σ+.

Cross-section Measurements for the Reactions $\nu p \to \mu^- \pi^+ p$ and $\nu p \to \mu^- K^+ p$ at High-Energies

Inspire Record 131344 DOI 10.17182/hepdata.24326

We present results for the reactions νp→μ−π+p and νp→μ−K+p at energies above 5 GeV. The average cross section for the first reaction between 15 and 40 GeV is (0.80±0.12) × 10−38 cm2 and for events with Mπ+p<1.4 GeV is (0.55±0.08) × 10−38 cm2. The ratio of the cross section for the second reaction to that for the first is 0.017±0.010.

Inclusive Negative Hadron Production from High Energy $\bar{\nu}$ Nucleus Charged Current Interactions

Berge, J.P. ; Bogert, D. ; Endorf, R. ; et al.
Phys.Rev.D 18 (1978) 3905, 1978.
Inspire Record 130082 DOI 10.17182/hepdata.24370

We present data on inclusive negative-hadron production from charged-current antineutrino interactions in a 21% Ne-H mixture. Inclusive single-particle distributions are presented and are shown to be insensitive to the momentum transferred to the hadron vertex. Comparisons made to inclusive data from π−p and π−n interactions indicate a close similarity between the hadrons resulting from π-nucleon and ν¯-nucleus interactions. The general features of the ν¯-nucleus data are found to be similar to those seen in ν¯p interactions. This last observation implies that ν¯p and ν¯n interactions are similar and that nuclear effects are small.

Inclusive Production of Nonstrange Resonances in High-Energy $\nu p$ Charged Current Interactions

Berge, J.P. ; Bogert, D.V. ; Endorf, R.J. ; et al.
Phys.Rev.D 22 (1980) 1043, 1980.
Inspire Record 144267 DOI 10.17182/hepdata.24174

We have examined the inclusive production of nonstrange particle resonances in νp interactions using the Fermilab 15-ft bubble chamber. A sample of 2437 charged-current events with visible longitudinal momentum greater than 10 GeV/c was obtained. The ρ0 and Δ++(1232) are seen. An overall rate of 0.21±0.04 ρ0 per event is found. For five-prong events, the rate is 0.44±0.08 ρ0 per event. The ρ0Z distribution falls rapidly for Z greater than 0.4. The production of Δ++ is seen clearly in events with an identified proton. No evidence is seen for Δ0 production. An upper limit of 0.34 is placed on the ratio of ηπ0 (90% confidence level).
