The dissociation of virtual photons, $\gamma^{\star} p \to X p$, in events with a large rapidity gap between $X$ and the outgoing proton, as well as in events in which the leading proton was directly measured, has been studied with the ZEUS detector at HERA. The data cover photon virtualities $Q^2>2$ GeV$^2$ and $\gamma^{\star} p$ centre-of-mass energies $40<W<240$ GeV, with $M_X>2$ GeV, where $M_X$ is the mass of the hadronic final state, $X$. Leading protons were detected in the ZEUS leading proton spectrometer. The cross section is presented as a function of $t$, the squared four-momentum transfer at the proton vertex and $\Phi$, the azimuthal angle between the positron scattering plane and the proton scattering plane. It is also shown as a function of $Q^2$ and $\xpom$, the fraction of the proton's momentum carried by the diffractive exchange, as well as $\beta$, the Bjorken variable defined with respect to the diffractive exchange.

Evidence for a New Pseudoscalar Meson

Bonesini, M. ; Donald, R.A. ; Edwards, D.N. ; et al.
Phys.Lett.B 103 (1981) 75-78, 1981.
Inspire Record 170357 DOI 10.17182/hepdata.31149

Performing a PWA of the π − π − π + system over the −t p/p range 0.2 to 0.4 GeV 2 we find evidence for a J P = 0 − , J G =1 − meson of mass 1342 ± 20 MeV and width 220 ±70 MeV decaying into ϵπ. This state is produced by natural parity exchange with a slope similar to that of elastic scattering. It can be interpreted as a radial excitation of the π meson (π′).

Study of the Reaction pi- p --> K0 Y* at 8.0-GeV/c, 10.7-GeV/c, and 15.7-GeV/c

Phys.Rev.D 15 (1977) 609, 1977.
Inspire Record 4145 DOI 10.17182/hepdata.24625

We present differential and total cross sections for the reactions π−p→K0[Σ(1385)Λ(1405)] and π−p→K0Λ(1520) at incident pion momenta of 8.0, 10.7, and 15.7 GeV/c. Pions from the decay of the forward K0s's were detected in the forward leg of the BNL double-vee spectrometer and the recoil Y* 's were identified by the missing-mass technique.

We have studied the reactions K+p→K0Δ++(1236) at 15.7 GeVc, K−p→K¯0n at 10.7 and 15.7 GeVc, and K−p→K¯0Δ0(1236) at 15.7 GeVc in the BNL Double Vee Magnetic Spectrometer. The π+ and π− from the decays of forward K0's were detected and the above reactions were identified by a missing-mass technique. Total and differential cross sections are presented for the first two reactions and a total cross section for the third.

Neutron-proton charge-exchange scattering, 3-12 gev/c

Miller, E.L. ; Elfield, M. ; Reay, N.W. ; et al.
Phys.Rev.Lett. 26 (1971) 984-987, 1971.
Inspire Record 69018 DOI 10.17182/hepdata.37275

We report a high-statistics measurement of the neutron-proton charge-exchange differential cross section for incident momenta 3 to 12 GeVc, and four-momentum transfers 0.003 to 0.85 (GeVc)2. The data are normalized absolutely to ±20%. The differential cross section is characterized by a sharp peak at small momentum transfers, with a gentler exponential behavior at large momentum transfers. This shape is remarkably independent of the incident momentum.
