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.

Study of the Inclusive Reactions $K^- p \to p$ X at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Babintsev, V.V. ; Borovikov, A.A. ; Buschbeck, B. ; et al.

In a K − p experiment at 32 GeV/ c with a sensitivity of 6 ev/≈b the inclusive reaction K − p → p + X was studied in the kinematical region x < −0.3. Most of the protons in this region were identified by ionization. Correcting for losses of the very slow as well as of the fast protons in this region we obtained σ p ( x < −0.3) = 5.9 ± 0.2 mb. The double invariant differential cross sections of protons were analysed in terms of the variables x , p T 2 , and M 2 / s , t , and the contributions from separate peripheral mechanisms were analysed. A triple-Regge analysis was performed on the inclusive proton d 2 σ /d t d( M 2 / s ) distribution with | t | < 1.1 GeV 2 . The fit with an RRP term resulted in an effective trajectory for the exchanged reggeon lying somewhat lower than that for the leading meson trajectory. Inclusion in the fit of an additional ππp term showed that pion exchange is important in the triple-Regge region at small | t |.

Diffraction Dissociation of High-Energy Protons in p d Interactions

Akimov, Y. ; Golovanov, L. ; Mukhin, S. ; et al.
Phys.Rev.Lett. 35 (1975) 766, 1975.
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.

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

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.
