This book was released on 2005 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents several observables for the reactions ? p → K+? and ? p → K+?°. In addition to measuring differential cross sections, we have made first measurements of the double polarization observables Cx and Cz. Cx and C z characterize the transfer of polarization from the incident photon to the produced hyperons. Data were obtained at Jefferson Lab using a circularly polarized photon beam at endpoint energies of 2.4, 2.9, and 3.1 GeV. Events were detected with the CLAS spectrometer. In the ? channel, the cross sections support the recent observation of new resonant structure at W = 1900 MeV. Studies of the invariant cross section, $d?/top{dt}$ show scaling behavior suggesting that the production mechanism becomes t-channel dominated near threshold at forward kaon angles. The double polarization observables show that the recoiling ? is almost maximally polarized along the direction of the incident photon from mid to forward kaon angles. While ?o differential cross sections are of the same magnitude as the ? differential cross sections, there is evidence of different physics dominating the production mechanism. The ?° invariant cross sections do not show the same t-scaling behavior present in the ? results. The double polarization observables indicate that the ?° is not polarized as strongly as the ?. They also fail to identify one preferred polarization axis. Complete interpretation of these results will rely on model calculations. Currently available isobar models obtain varying degrees of success while attempting to predict the double polarization observables. While the models are in better agreement with the differential cross sections, discrepancies with our cross sections indicate that they must be re-optimized in light of the new data. While the data suggest that a Regge model would provide a good description of K+? over most of the range in W, the available Regge calculation overstates the strength of the cross section and does not predict Cx and Cz correctly.

Available in PDF, EPUB and Kindle. Book excerpt: The cross sections are measured for K−p $Yields$ anti K°n at 520 to 1060 MeV/c and for anti pp $Yields$ anti nn from 270 to 960 MeV/c with a typical point-to-point precision of about 1 percent. The cross sections in preliminary form are shown and discussed. It is suggested that the spin of the [Sigma](1590) must be at least 2/3 and that of a possible resonance at the bump at 475 MeV/c must be at least 4. (JFP).

Available in PDF, EPUB and Kindle. Book excerpt: Here, high-statistics measurements of differential cross sections and recoil polarizations for the reaction $\gamma p \rightarrow K+̂ \Sigma0̂$ have been obtained using the CLAS detector at Jefferson Lab. We cover center-of-mass energies ($\sqrt{s}$) from 1.69 to 2.84 GeV, with an extensive coverage in the $K+̂$ production angle. Independent measurements were made using the $K{̂+}p\pi{̂-}$($\gamma$) and $K{̂+}p$($\pi-̂,\gamma$) final-state topologies, and were found to exhibit good agreement. Our differential cross sections show good agreement with earlier CLAS, SAPHIR and LEPS results, while offering better statistical precision and a 300-MeV increase in $\sqrt{s}$ coverage. Above $\sqrt{s} \approx 2.5$ GeV, $t$- and $u$-channel Regge scaling behavior can be seen at forward- and backward-angles, respectively. Our recoil polarization ($P_\Sigma$) measurements represent a substantial increase in kinematic coverage and enhanced precision over previous world data. At forward angles we find that $P_\Sigma$ is of the same magnitude but opposite sign as $P_\Lambda$, in agreement with the static SU(6) quark model prediction of $P_\Sigma \approx -P_\Lambda$. This expectation is violated in some mid- and backward-angle kinematic regimes, where $P_\Sigma$ and $P_\Lambda$ are of similar magnitudes but also have the same signs. In conjunction with several other meson photoproduction results recently published by CLAS, the present data will help constrain the partial wave analyses being performed to search for missing baryon resonances.
