Diffraction Dissociation of Photons on Hydrogen

Chapin, T.J. ; Cool, R.L. ; Goulianos, Konstantin A. ; et al.
Phys.Rev.D 31 (1985) 17-30, 1985.
Inspire Record 216071 DOI 10.17182/hepdata.4332

We report results from a measurement of the inclusive diffraction dissociation of photons on hydrogen, γp→Xp, in the range 75<pγ<148 GeV/c, 0.02<‖t‖<0.1 (GeV/c)2, and MX2/s<0.1. Our data show an exponential t dependence and a dominant 1/MX2 behavior for MX2>4 GeV2. We test the finite-mass sum rule and, by comparing γp with π−p data obtained in the same apparatus, we test factorization.

New results on n p ---> d gamma, and time-reversal invariance

Bartlett, D.F. ; Friedberg, C.E. ; Goldhagen, P.E. ; et al.
Phys.Rev.Lett. 27 (1971) 881-885, 1971.
Inspire Record 68910 DOI 10.17182/hepdata.21459

The angular distribution for the reaction n+p→d+γ has been measured at neutron energies of 475, 560, 625, and 750 MeV. Results based on 31 000 events at nine scattering angles are reported and compared with existing data for the inverse reaction, γ+d→n+p. The angular distributions are found to agree, as predicted by time-reversal invariance.

Cool, R.L. ; Goulianos, Konstantin A. ; Segler, S.L. ; et al.
Phys.Rev.Lett. 48 (1982) 1451-1454, 1982.
Inspire Record 180508 DOI 10.17182/hepdata.20611

A measurement is reported of charged multiplicity distributions of high-mass diffractive π±, K±, and p± states produced in 100 and 200 GeV/c hadron-proton collisions, h+p→X+p. The distributions are described well by a Gaussian function that depends only on the available mass M=Mx−Mh, has a maximum at n0≅2M12, and a peak-to-width ratio n0D≅2.

Phys.Rev.D 24 (1981) 2821, 1981.
Inspire Record 156145 DOI 10.17182/hepdata.24029

We report on a measurement of elastic differential cross sections for p±p, π±p, and K±p at 100 and 200 GeV/c in the range 0.03<|t|<0.10 (GeV/c)2. Our data display a simple exponential dependence which is consistent with other measurements in this t region or with extrapolations from higher t.

Diffraction Dissociation of High Energy Protons on Hydrogen and Deuterium Targets

Phys.Rev.Lett. 39 (1977) 1432, 1977.
Inspire Record 121766 DOI 10.17182/hepdata.21002

We report results from a measurement of the inclusive processes pp→Xp and pd→Xd in the range 5<Mx2s<0.1, 0.01≲|t|≲0.1 (GeV/c)2, and incident proton momenta of 65, 154, and 372 GeV/c. Both pp and pd data show an exponential t dependence and a dominant 1Mx2 behavior for Mx2s≲0.05. By comparing pp and pd data we test factorization and, using the Glauber model, we measure the XN total cross section, σXN=43±10 mb.

Excitation of High-Energy Protons Into Low Mass States in p d Interactions

Akimov, Y. ; Golovanov, L. ; Mukhin, S. ; et al.
Phys.Rev.Lett. 35 (1975) 763, 1975.
Inspire Record 99830 DOI 10.17182/hepdata.21129

We have measured p−d inelastic scattering at small momentum transfer by detecting the slow-recoil deuterons from a deuterium-gas-jet target. The coherent diffraction dissociation of protons on deuterons was studied in the region 0.03<|t|<0.07 (GeV/c)2, 1.4<MX2<4 GeV2, and for energies from 50 to 275 GeV. In this region, the diffractive cross section exhibits structure and is dominated by an enhancement at MX2∼1.9 GeV2.

Diffraction Dissociation of High-Energy Protons in p d Interactions

Inspire Record 99831 DOI 10.17182/hepdata.21128

We report results from a measurement of the inclusive process p+d→X+d in the region 0.03<|t|<0.12 (GeV/c)2 and 5 GeV2<MX2≲0.11plab for incident proton momenta from 150 to 400 GeV/c. We find that in this region, the differential cross section d2σdtdMX2 varies only slowly with energy, falls exponentially with |t|, and behaves to a good approximation as 1MX2. The measurement was performed at Fermilab by detecting slow-recoil deuterons from a deuterium-gas-jet target placed at the internal beam of the accelerator.

Precise Comparison of Anti-proton - Proton and Proton Proton Forward Elastic Scattering at $\sqrt{s}=24$.3-{GeV}

The UA6 collaboration Breedon, R.E. ; Chapin, T.J. ; Cool, R.L. ; et al.
Phys.Lett.B 216 (1989) 459-465, 1989.
Inspire Record 267044 DOI 10.17182/hepdata.29854

We report results from a measurement of antiproton-proton and proton-proton small-angle elastic scattering at √ s = 24.3 GeV in the range 0.001 ⩽ | t | ⩽ 0.06 (GeV/ c ) 2 . The measurement was performed at the CERN p p Collider by using silicon detectors to observe protons recoiling from a hydrogen cluster-jet target intercepting the stored p and p beams. Fits to the measured differential cross sections yield the ratio of the real to the imaginary part of the forward nuclear scattering amplitude ρ and the nuclear slope parameter b for both p p and pp. We find that the difference Δρ = ρ ( p p ) − ρ( pp ) = 0.031 ± 0.010 agrees with conventional fits and disagrees with the “odderon” fit designed to accommodate the recent UA4 measurement of ρ( p p) at 546 GeV.

Proton - Deuteron Elastic Scattering at Small Momentum Transfer from 50-GeV/c to 400-GeV/c

Akimov, Y. ; Golovanov, L. ; Mukhin, S. ; et al.
Phys.Rev.D 12 (1975) 3399, 1975.
Inspire Record 99829 DOI 10.17182/hepdata.24883

Proton-deuteron elastic scattering has been measured in the four-momentum transfer squared region 0.013<|t|<0.14 (GeV/c)2 and for incident proton beam momenta from 50 to 400 GeV/c. The data can be fitted with the Bethe interference formula. We observe shrinkage of the diffraction cone with increasing energy equal to (0.94±0.04)ln(s1 GeV2) (GeV/c)−2. This shrinkage is greater than that observed in pp elastic scattering. The ratio of the elastic to the total cross section is approximately 0.1 and independent of energy above ∼ 150 GeV. In order to extract information on pn scattering we fit our data using the Glauber approach and a form factor which is the sum of exponentials. The values we obtain for the slope parameter in pn scattering are sensitive to the details of the inelastic double-scattering term.
