Probing Strangeness in Hard Processes
H. Avakian, M. Battaglieri, E. Cisbani +11
Since the discovery of strangeness almost five decades ago, interest in this degree of freedom has grown up and now its investigation spans the scales from quarks to nuclei. Measur…
Measurement of the N to Delta(1232) Transition at High Momentum Transfer by pi0 Electroproduction
M. Ungaro, P. Stoler, I. Aznauryan +4
We report a new measurement of the exclusive electroproduction reaction gamma* p -> pi0 p to explore the evolution from soft non-perturbative physics to hard processes via the Q2 d…
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 pentaquark in the reaction
B. McKinnon, K. Hicks
A search for the \thp in the reaction was completed using the CLAS detector at Jefferson Lab. A study of the same reaction, published earlier, reported the observ…
Deeply virtual and exclusive electroproduction of omega mesons
CLAS collaboration, L. Morand
The exclusive omega electroproduction off the proton was studied in a large kinematical domain above the nucleon resonance region and for the highest possible photon virtuality (Q2…
Exclusive meson electroproduction from hydrogen at CLAS
C. Hadjidakis
The longitudinal and transverse components of the cross section for the reaction were measured in Hall B at Jefferson Laboratory using the CLAS detector. Th…
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 meson photoproduction to high momentum transfer, we measured the polar angular decay distribution of the outgoing in the…
Observation of an Exotic Baryon with S=+1 in Photoproduction from the Proton
V. Kubarovsky
The reaction 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…
Measurement of Beam-Spin Asymmetries for Deep Inelastic 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…
First Measurement of Transferred Polarization in the Exclusive e p --> e' K+ Lambda Reaction
CLAS Collaboration, D. S. Carman
The first measurements of the transferred polarization for the exclusive ep --> e'K+ Lambda reaction have been performed in Hall B at the Thomas Jefferson National Accelerator Faci…
Measurement of and baryon resonance analysis
M. Ripani
The cross section for the reaction was measured in the resonance region for 1.4W2.1 GeV and 0.51.5 GeV/c using the CL…
Observation of exclusive DVCS in polarized electron beam asymmetry measurements
CLAS Collaboration, S. Stepanyan
We report the first results of the beam spin asymmetry measured in the reaction e + p -> e + p + gamma at a beam energy of 4.25 GeV. A large asymmetry with a sin(phi) modulation is…
Electroproduction of the hyperon
S. P. Barrow
The reaction with was studied at electron beam energies of 4.05, 4.25, and 4.46 GeV, using the CLAS detector at the Thomas Jefferson Natio…
