Pi0 and pi+ Production with Polarized Photons in the Energy Range 1-GeV - 2-GeV

Abrahamian, L.O. ; Avakian, R.O. ; Aganyants, Aleksandr O. ; et al.
Phys.Lett.B 48 (1974) 463-466, 1974.
Inspire Record 90760 DOI 10.17182/hepdata.43798

The asymmetry of π o and π + photoproduction from hydrogen has been measured. The π o -mesons were detected at 130° cms with E γ ranged from 0.9 to 1.65 GeV, and the π + -mesons at 40° cms with E γ ranged from 0.9 to 1.2 GeV. The results agree with model predictions of single pion photoproduction in the resonance region using fixed- t dispersion relations.

Separated structure functions for the exclusive electroproduction of K+ Lambda and K+ Sigma0 final states.

We report measurements of the exclusive electroproduction of $K^+\Lambda$ and $K^+\Sigma^0$ final states from a proton target using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The separated structure functions $\sigma_T$, $\sigma_L$, $\sigma_{TT}$, and $\sigma_{LT}$ were extracted from the $\Phi$- and $\epsilon$-dependent differential cross sections taken with electron beam energies of 2.567, 4.056, and 4.247 GeV. This analysis represents the first $\sigma_L/\sigma_T$ separation with the CLAS detector, and the first measurement of the kaon electroproduction structure functions away from parallel kinematics. The data span a broad range of momentum transfers from $0.5\leq Q^2\leq 2.8$ GeV$^2$ and invariant energy from $1.6\leq W\leq 2.4$ GeV, while spanning nearly the full center-of-mass angular range of the kaon. The separated structure functions reveal clear differences between the production dynamics for the $\Lambda$ and $\Sigma^0$ hyperons. These results provide an unprecedented data sample with which to constrain current and future models for the associated production of strangeness, which will allow for a better understanding of the underlying resonant and non-resonant contributions to hyperon production.

Proton Polarization in $p p$ Elastic and Inclusive Processes at Beam Momenta From 20-{GeV}/$c$ to 400-{GeV}/$c$

Corcoran, M. ; Ems, S.C. ; Gray, S.W. ; et al.
Phys.Rev.D 22 (1980) 2624, 1980.
Inspire Record 9773 DOI 10.17182/hepdata.4324

The polarization of the recoil proton has been measured in both high-energy elastic and inclusive proton-proton scattering at the internal-target area of Fermi National Accelerator Laboratory. The polarization in elastic scattering was measured at a number of center-of-mass energies up to s=19.7 GeV. Indications of negative polarization were seen at the higher center-of-mass energies for t values of -0.6, -0.8, and -1.0 (GeV/c)2. In the inclusive process p+p→p↑+X the polarization was found to be independent of beam energy from 100 to 400 GeV for xF values of -0.7, -0.8, -0.9. The polarization at PT=1.0 GeV/c, xF=−0.7 and xF=−0.8 was less than 2.5%. This is significantly lower than the corresponding measurements reported for Λ0 inclusive polarization.

The results of an experiment conducted at Fermilab to measure the polarization of the final-state proton in the reaction p+p→p↑+X and p+C→p↑+X are presented. Measurements were made at beam energies of 100, 200, 300, and 400 GeV for PT from 0.5 to 1.5 GeV/c and xF between - 0.7 and - 0.9.
