A Study of Charged Pseudoscalar Meson Photoproduction From Hydrogen and Deuterium With 16-{GeV} Linearly Polarized Photons

Quinn, D.J. ; Rutherfoord, J.P. ; Shupe, M.A. ; et al.
Phys.Rev.D 20 (1979) 1553, 1979.
Inspire Record 140543 DOI 10.17182/hepdata.24208

The asymmetries in forward π−N, π−Δ, and K+−(Λ+Σ) photoproduction have been measured with a 16-GeV linearly polarized beam. The experimental method and the procedures for extracting cross sections and asymmetries from the data are discussed in detail. Information on the energy and momentum-transfer dependence of cross sections for natural- and unnatural-parity exchange, interference between exchanges of opposite G parity, and vector-meson dominance is obtained and discussed.

Polarization Analyzing Power Ay (theta) in pp Elastic Scattering at 643, 787, and 796 MeV

Bevington, P.R. ; McNaughton, M.W. ; Willard, H.B. ; et al.
Phys.Rev.Lett. 41 (1978) 384-387, 1978.
Inspire Record 139918 DOI 10.17182/hepdata.20830

Data have been obtained for the polarization analyzing power Ay(θ) in pp elastic scattering from near 30° to 90° (c.m.) at 643, 787, and 796 MeV. Relative uncertainties are typically ± 0.003 with an overall normalization uncertainty of {+1}{−0.5}%. Data are not consistent with existing phase-shift analyses.

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.

Measurement of the polarization parameter in n p charge-exchange scattering from 2 to 12 gev/c

Abolins, M.A. ; Lin, M.T. ; Ruchti, R.C. ; et al.
Phys.Rev.Lett. 30 (1973) 1183-1185, 1973.
Inspire Record 84508 DOI 10.17182/hepdata.21408

We have measured the polarization parameter in neuton-proton charge-exchange scattering for incident neutron momenta of 2-12 GeVc and 0.01<~|t|<~1.0 (GeVc)2. Results based on 300 000 events show a negative polarization whose magnitude increases monotonically with |t| approaching 60% for |t|∼0.6 and which has little energy dependence.

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.

Sigma+ polarization in pi+ n ---> k0 sigma+ from 1.1 to 2.4 gev/c

Phys.Rev.D 7 (1973) 3546-3548, 1973.
Inspire Record 82052 DOI 10.17182/hepdata.22133

We observe an energy-dependent polarization of the Σ+ produced in the reaction π+n→K0Σ+ at incident beam momenta between 1.1 and 2.4 GeV/c. These data form a significant source of information on the Σ− polarization in the charge-symmetric reaction π−p→K+Σ−.
