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…

Does the Sigma(1580)3/2- resonance exist?

Crystal Ball Collaboration, J. Olmsted, S. Prakhov +34

Precise new data for the reaction $K^{-} p \to π^{0} Λ$ are presented in the c.m. energy range 1565 to 1600 MeV. Our analysis of these data sheds new light on claims for the $Σ(1580){3…

Measurement of $e p \to e^{^{'}} p π^{+} π^{-}$ : experimental procedures and baryon resonance analysis

M. Ripani, V. D. Burkert, V. Mokeev +4

The cross section for the reaction $e p \to e^{'} p π^{+} π^{-}$ was measured in the resonance region for 1.4 $<$ W $<$ 2.1 GeV and 0.5 $< Q^{2} <$ 1.5 GeV $^{2}$ /c $^{2}$ using the CL…

Nucleon and Hyperon Resonances with the Crystal Ball

Crystal Ball Collaboration, W. J. Briscoe, A. Shafi +1

The Crystal Ball Spectrometer is being used at Brookhaven National Laboratory in a series of experiments which study all neutral final states of pi-p and K-p induced reactions. We…
