Observation of eta_c^{prime} Production in gamma gamma Fusion at CLEO

D. M. Asner, CLEO Collaboration

We report on the observation of the eta_{c}^{prime}(2^{1}S_{0}), the radial excitation of eta_{c}(1^{1}S_{0}) ground state of charmonium, in the two-photon fusion reaction gamma ga…

Tensor Polarization of the phi meson Photoproduced at High t

K. McCormick, the CLAS collaboration

As part of a measurement of the cross section of $ϕ$ meson photoproduction to high momentum transfer, we measured the polar angular decay distribution of the outgoing $K^{+}$ in the…

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…

Two-Nucleon Momentum Distributions Measured in 3He(e,e'pp)n

CLAS Collaboration, R. A. Niyazov, L. B. Weinstein

We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for `fast' nucleons (p > 250 MeV/c) peaks where two nucleons each…

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 Beam-Spin Asymmetries for Deep Inelastic $π^{+}$ Electroproduction

CLAS Collaboration, H. Avakian

We report the first evidence for a non-zero beam-spin azimuthal asymmetry in the electroproduction of positive pions in the deep-inelastic region. Data have been obtained using a p…
