Inclusive $\pi^0$ Production by High-Energy Protons

Carey, David C. ; Johnson, J.R. ; Kammerud, R. ; et al.
Phys.Rev.D 14 (1976) 1196, 1976.
Inspire Record 99992 DOI 10.17182/hepdata.4894

Measurements of the cross section for the reaction p+p→π0+anything have been completed. The data cover a range of incident proton energies 50-400 GeV, π0 transverse momenta 0.3-4 GeV/c, and laboratory angles 30-275 mrad. The experiment was performed using the internal proton beam at the Fermi National Accelerator Laboratory. A lead-glass counter was used to detect photons from the decay of π0's produced by collisions in thin targets of hydrogen or carbon. Tables of the measured cross sections are presented.

Photoproduction of the psi Particles

Camerini, U. ; Learned, J.G. ; Prepost, R. ; et al.
Phys.Rev.Lett. 35 (1975) 483, 1975.
Inspire Record 100670 DOI 10.17182/hepdata.21149

The s and t dependence of incoherent ψ(3100) photoproduction from deuterium has been measured at the Stanford Linear Accelerator Center. ψ(3700) photoproduction and ψ(3100) photoproduction from hydrogen have also been measured.

Polarized Photon Asymmetries in K+ Photoproduction at 16-GeV

Quinn, D.J. ; Rutherfoord, J.P. ; Shupe, M.A. ; et al.
Phys.Rev.Lett. 34 (1975) 543, 1975.
Inspire Record 100595 DOI 10.17182/hepdata.21241

Using a 16-GeV linearly polarized photon beam, we have measured asymmetries in the process γN→K+(Λ+Σ) from hydrogen and deuterium, for square of four-momentum transfer, t, between -0.01 and -0.8 (GeV/c)2. The data show that for −t≳0.1 (GeV/c)2, the cross sections for γp→K+Λ, γp→K+Σ0, and γn→K+Σ− are strongly dominated by natural-parity exchange, as is the case in single-pion photoproduction.

The Ratio of Deep - Inelastic e-n to e-p Cross-Sections in the Threshold Region

Bodek, A. ; Dubin, D.L. ; Elias, J.E. ; et al.
Phys.Lett.B 51 (1974) 417-420, 1974.
Inspire Record 91646 DOI 10.17182/hepdata.27946

We report measurements of the ratio of the deep-inelastic electron-neutron to electron-proton differential cross sections in the threshold ( ω <3) region. The ratio was found to scale and to decrease monotically with decreasing ω . No violation of the quark model lower bound of 0.25 was observed in the ratio.

ASYMMETRIES IN CHARGED PION PHOTOPRODUCTION ON NUCLEONS BY 16-GeV POLARIZED PHOTONS

Sherden, D. ; Siemann, R. ; Sinclair, Charles K. ; et al.
Phys.Rev.Lett. 30 (1973) 1230, 1973.
Inspire Record 81026 DOI 10.17182/hepdata.21357

Asymmetries in charged-pion photoproduction from hydrogen and deuterium have been measured with 16-GeV linearly polarized photons. Considerable energy dependence is seen in the natural-parity contribution to the π−π+ ratio from deuterium, and in the unnatural-parity part of the cross section for γn→π−p. The energy dependence of this latter cross section is consistent with the expected from a conventional pion Regge trajectory.

FORWARD COMPTON SCATTERING FROM HYDROGEN AND DEUTERIUM AT 8-GeV AND 16-GeV

Boyarski, A. ; Coward, D.H. ; Ecklund, Stanley D. ; et al.
Phys.Rev.Lett. 26 (1971) 1600-1604, 1971.
Inspire Record 67269 DOI 10.17182/hepdata.21513

Compton-scattering cross sections from hydrogen (γp→γp) and from deuterium have been measured at four-momentum transfer t in the range 0.014<~−t<~0.17 GeV2 and photon energies of 8 and 16 GeV. Fits to our proton data of the form dσdt=AeBt give B≈7.8 GeV−2 and an intercept A which is in agreement with the optical point. Both coherent scattering from deuterons and incoherent scattering from neutrons and protons are seen from deuterium. A small difference between the neutron and proton cross sections is seen, indicating the presence of about a 3% isovector t-channel exchange amplitude in addition to the predominant isoscalar amplitude. The vector-dominance model predicts lower cross sections (by at least 20%) for both the hydrogen and deuterium cases.
