The exclusive reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}p{K}^{+}{K}^{\ensuremath{-}}$ was studied in the photon energy range $3.0--3.8\text{ }\text{ }\mathrm{GeV}$ and momentum transfer range $0.6<\ensuremath{-}t<1.3\text{ }\text{ }{\mathrm{GeV}}^{2}$. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. In this kinematic range the integrated luminosity …

We report the first measurement of differential and total cross sections for the $\ensuremath{\gamma}d\ensuremath{\rightarrow}{K}^{0}\mathrm{\ensuremath{\Lambda}}(p)$ reaction, using data from the CLAS detector at the Thomas Jefferson National Accelerator Facility. Data collected during two separate experimental runs were studied with photon-energy coverage 0.8--3.6 GeV …

The ${f}_{1}(1285)$ meson with mass $1281.0\ifmmode\pm\else\textpm\fi{}0.8$ MeV/${c}^{2}$ and width $18.4\ifmmode\pm\else\textpm\fi{}1.4$ MeV (full width at half maximum) was measured for the first time in photoproduction from a proton target using CLAS at Jefferson Lab. Differential cross sections were obtained via the $\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}},\phantom{\rule{0.28em}{0ex}}{K}^{+}{\overline{K}}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$, and …

High-statistics measurements of differential cross sections and spin density matrix elements for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\phi}p$ have been made using the CLAS detector at Jefferson Lab. We cover center-of-mass energies ($\sqrt{s}$) from 1.97 to 2.84 GeV, with an extensive coverage in the $\ensuremath{\phi}$ …

Beam asymmetries for the reactions $\ensuremath{\gamma}p\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{0}$ and $\ensuremath{\gamma}p\ensuremath{\rightarrow}n{\ensuremath{\pi}}^{+}$ have been measured with the CEBAF Large Acceptance Spectrometer (CLAS) and a tagged, linearly polarized photon beam with energies from 1.102--1.862 GeV. A Fourier moment technique for extracting beam asymmetries from experimental data is …

The electromagnetic decay ${\ensuremath{\Sigma}}^{0}(1385)\ensuremath{\rightarrow}\ensuremath{\Lambda}\ensuremath{\gamma}$ was studied using the CLAS detector at the Thomas Jefferson National Accelerator Facility. A real photon beam with a maximum energy of 3.8 GeV was incident on a proton target, producing an exclusive final state of ${K}^{+}{\ensuremath{\Sigma}}^{*0}$. We …

High-statistics measurements of differential cross sections and recoil polarizations for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\Sigma}}^{0}$ 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. …
