Search for the $Θ^{+}$ pentaquark in the reactions $γ p \to K ˉ^{0} K^{+} n$ and $γ p \to K ˉ^{0} K^{0} p$

R. De Vita, M. Battaglieri, V. Kubarovsky +9

The exclusive reactions $γ p \to K ˉ^{0} K^{+} n$ and $γ p \to K ˉ^{0} K^{0} p$ have been studied in the photon energy range 1.6--3.8 GeV, searching for evidence of the exotic baryon $…

Measurement of the $x$ - and $Q^{2}$ -Dependence of the Asymmetry $A_{1}$ on the Nucleon

K. V. Dharmawardane, S. E. Kuhn, P. Bosted +1

We report results for the virtual photon asymmetry $A_{1}$ on the nucleon from new Jefferson Lab measurements. The experiment, which used the CEBAF Large Acceptance Spectrometer and…

Search for $Θ^{++}$ Pentaquarks in the Exclusive Reaction $γ p \to K^{+} K^{-} p$

V. Kubarovsky, M. Battaglieri, R. De Vita +6

The reaction $γ p \to p K^{+} K^{-}$ was studied at Jefferson Lab with photon energies from 1.8 to 3.8 GeV using a tagged photon beam. The goal was to search for a $Θ^{++}$ pentaquark, a…

Search for the Theta+ pentaquark in the gamma d -> Lambda n K+ reaction measured with CLAS

Clas Collaboration, S. Niccolai

For the first time, the reaction gamma d -> Lambda n K+ has been analyzed in order to search for the exotic pentaquark baryon Theta+(1540). The data were taken at Jefferson Lab, us…

Search for the $Θ^{+}$ pentaquark in the reaction $γ d \to p K^{-} K^{+} n$

B. McKinnon, K. Hicks

A search for the \thp in the reaction $γ d \to p K^{-} K^{+} n$ was completed using the CLAS detector at Jefferson Lab. A study of the same reaction, published earlier, reported the observ…
