Exclusive Photoproduction of the Cascade (Xi) Hyperons

J. W. Price

We report on the first measurement of exclusive Xi-(1321) hyperon photoproduction in gamma p --> K+ K+ Xi- for 3.2 < E(gamma) < 3.9 GeV. The final state is identified by the missin…

Observation of an Exotic Baryon with S=+1 in Photoproduction from the Proton

V. Kubarovsky

The reaction $γ p \to π^{+} K^{-} K^{+} n$ was studied at Jefferson Lab using a tagged photon beam with an energy range of 3-5.47 GeV. A narrow baryon state with strangeness S=+1 and mass $M…

Observation of an Exotic $S = + 1$ Baryon in Exclusive Photoproduction from the Deuteron

S. Stepanyan, The CLAS collaboration

In an exclusive measurement of the reaction $γ d \to K^{+} K^{-} p n$ , a narrow peak that can be attributed to an exotic baryon with strangeness $S = + 1$ is seen in the $K^{+} n$ invariant m…

Measurement of the Proton Spin Structure Function $g_{1} (x, Q^{2})$ for $Q^{2}$ from 0.15 to 1.6 GeV $^{2}$ with CLAS

R. Fatemi, A. V. Skabelin, V. D. Burkert +5

Double-polarization asymmetries for inclusive $e p$ scattering were measured at Jefferson Lab using 2.6 and 4.3 GeV longitudinally polarized electrons incident on a longitudinally p…

Photoproduction of the $ω$ meson on the proton at large momentum transfer

M. Battaglieri, M. Brunoldi, R. De Vita +4

The differential cross section, $d σ / d t$ for $ω$ meson exclusive photoproduction on the proton above the resonance region ( $2.6 < W < 2.9$ GeV) was measured up to a momentum transfer $-…

DRAFT: Photoproduction of the $ρ^{0}$ meson on the proton at large momentum transfer

CLAS collaboration, M. Battaglieri

The differential cross section, $d σ / d t$ , for $ρ^{0}$ meson photoproduction on the proton above the resonance region ( $2.6 < W < 2.9$ GeV) was measured up to a momentum transfer $- t = 5$ …
