Photoproduction of neutral rho mesons

Mcclellan, G. ; Mistry, Nari B. ; Mostek, P. ; et al.
Phys.Rev.D 4 (1971) 2683-2693, 1971.
Inspire Record 74765 DOI 10.17182/hepdata.23152

Results are presented on a series of measurements of ρ-photoproduction from hydrogen, deuterium, and complex nuclei ranging up to lead, at photon energies ranging from 4 to 9 GeV. Detailed dipion mass-spectrum fits are presented, using a Drell-type nonresonant background and its interference with the resonant amplitude, with no other arbitrary backgrounds. For hydrogen and deuterium, the inelastic contributions have been subtracted. The A dependence of the cross sections is analyzed to yield values of γρ24π and σρN at average photon energies of 6.1, 6.5, and 8.8 GeV. The hydrogen-to-deuterium ratios indicate the presence of possible nondiffractive amplitudes at low energies which then decrease with energy.

Nucleon-Nucleon Total Cross Sections from 1.1 to 8 GeV/c

Bugg, D.V. ; Salter, D.C. ; Stafford, G.H. ; et al.
Phys.Rev. 146 (1966) 980-992, 1966.
Inspire Record 50610 DOI 10.17182/hepdata.408

Measurements have been made of the total cross sections σ(p−p) and σ(p−d) over the laboratory momentum range 1.1 to 8 GeV/c, with relative errors of 0.1%. The absolute accuracies of these cross sections are limited to 0.3% by lack of information which will allow the Coulomb-nuclear interference to be calculated accurately. Values of the total cross sections σ(p−n) and σ(I=0) are deduced by assuming the Glauber correction. Structure is observed in σ(p−p) near a mass value of 2.75 GeV/c2; its interpretation is discussed. σ(I=0) rises rapidly in the range 2.3 to 2.9 GeV/c2, and this is attributed to the onset of strong inelastic scattering.

Total Cross-sections for Muon-neutrino $N$ and Muon-neutrino $P$ Charged Current Interactions in the 7-ft Bubble Chamber

Baker, N.J. ; Connolly, P.L. ; Kahn, S.A. ; et al.
Phys.Rev.D 25 (1982) 617-623, 1982.
Inspire Record 177607 DOI 10.17182/hepdata.23972

The total cross sections for νμn and νμp charged-current interactions and their ratio R=σT(νn)σT(νp) have been measured as a function of neutrino energy from 0.4 to 10 GeV. The experiment is performed using the BNL 7-foot deuterium bubble chamber exposed to the Alternating Gradient Synchrotron wide-band neutrino beam. The absolute values of the cross sections are normalized to the quasielastic scattering (νμn→μ−p) cross section. Above 1.6 GeV the data are consistent with the quark-parton model. We find that σT(νn)Eν=(1.07±0.05)×10−38, σT(νp)Eν=(0.54±0.04)×10−38, and σT(νN)Eν=(0.80±0.03)×10−38 cm2/GeV for 〈Eν〉=3.2 GeV, and R=1.95±0.10 for 〈Eν〉=3.7 GeV.

The s Dependence of Proton Fragmentation by Hadrons. 2. Incident Lab Momenta 30-GeV/c - 250-GeV/c

Weisberg, H. ; Beier, E. ; Brody, H. ; et al.
Phys.Rev.D 17 (1978) 2875, 1978.
Inspire Record 122402 DOI 10.17182/hepdata.24404

Measurements of inclusive scattering in the target-fragmentation region are extended to higher incident energy. The combined data set shows departures from an approach to the asymptotic scaling limit as A+Bs−12 that are significant even at the highest energies. When these departures are taken into account, the data approach a limit that is consistent with equal cross sections induced by particles and antiparticles and with Pomeron factorization. The corrections to A+Bs−12 are so large that detailed tests of Mueller-Regge relationships are not conclusive.

Forward Produced Protons and Anti-protons in Deep Inelastic Muon Proton Scattering

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 103 (1981) 388, 1981.
Inspire Record 166178 DOI 10.17182/hepdata.31185

A significant rate of forward proton and antiproton production has been observed in 120 and 280 GeV muon-proton scattering. The z and p T 2 distributions are presented. The dependence of the normalized production cross section on the muon variables x and Q 2 is studied.

K+ P ELASTIC SCATTERING AT 3.5-GeV/c AND 5.0-GeV/c

De Baere, W. ; Debaisieux, J. ; Dufour, J.P. ; et al.
Nuovo Cim.A 45 (1966) 885, 1966.
Inspire Record 50048 DOI 10.17182/hepdata.37572

The elastic scattering of K+ mesons on protons is studied at 3.5 and 5 GeV/c. The total elastic cross-sections are found to be (4.36±0.36) mb and (3.82±0.41) mb respectively. The differential elastic cross-sections, which exhibit characteristic diffraction peaks, are fitted by dσ/dt=(dσ/dt)0eαt, giving α=(3.85±0.12) and (4.70±0.21) (GeV/c)−2 for the two momenta respectively, with |t|⪝0.65 (GeV/c)2. The results are compared to those at neighbouring energies, giving some support to the presence of a real part of the forward scattering amplitude. The diffraction peak shows definite shrinking with increasing momenta. The data are examined in the light of models for high-energy scattering.
