Helicity Asymmetry Measurement for Photoproduction on the CLAS Frozen Spin Target
Diane Schott, William Briscoe, Igor Strakovsky
The measurement was performed with circularly polarized photons incident on longitudinally polarized target in Hall B at the Thomas Jefferson National Accelerator Facility. The hel…
First measurement of the helicity asymmetry in photoproduction on the proton
I. Senderovich, B. T. Morrison, M. Dugger +148
Results are presented for the first measurement of the double-polarization helicity asymmetry E for the photoproduction reaction . Data were obtained using t…
Measurement of pi^0 photoproduction on the proton at MAMI C
P. Adlarson, F. Afzal, C. S. Akondi +88
Differential cross sections for the gamma p -> pi^0 p reaction have been measured with the A2 tagged-photon facilities at the Mainz Microtron, MAMI C, up to the center-of-mass ener…
Toward Complete Pion Nucleon Amplitudes
V. Mathieu, I. V. Danilkin, C. Fernández-Ramírez +4
We compare the low-energy partial wave analyses scattering with a high-energy data via finite energy sum rules. We construct a new set of amplitudes by matching the imaginary…
Precise Determination of the Deuteron Spin Structure at Low to Moderate with CLAS and Extraction of the Neutron Contribution
N. Guler, R. G. Fersch, S. E. Kuhn +126
We present the final results for the deuteron spin structure functions obtained from the full data set collected with Jefferson Lab's CLAS in 2000-2001. Polarized electrons with en…
Three-body Final State Interaction in
Peng Guo, Igor V. Danilkin, Diane Schott +3
We present an unitary dispersive model for the decay process based upon the Khuri-Treiman equations which are solved by means of the Pasquier inversion method. The descr…
Cross sections for the exclusive photon electroproduction on the proton and Generalized Parton Distributions
H. S. Jo, F. X. Girod, H. Avakian +7
Unpolarized and beam-polarized four-fold cross sections for the reaction were measured using the CLAS detector and the 5…
Determination of the Beam-Spin Asymmetry of Deuteron Photodisintegration in the Energy Region GeV
Nicholas Zachariou, Yordanka Ilieva, Nikolay Ya. Ivanov +140
The beam-spin asymmetry, , for the reaction has been measured using the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerato…
First Measurement of the Polarization Observable E in the Reaction up to 2.25 GeV
S. Strauch, W. J. Briscoe, M. Döring +165
First results from the longitudinally polarized frozen-spin target (FROST) program are reported. The double-polarization observable E, for the reaction , has…
A new measurement of the neutron detection efficiency for the NaI Crystal Ball detector
M. Martemianov, V. Kulikov, B. T. Demissie +68
We report on a measurement of the neutron detection efficiency in NaI crystals in the Crystal Ball detector obtained from a study of single p0 photoproduction on deuterium using th…
