We measured the g(1) spin structure function of the deuteron at low Q(2), where QCD can be approximated with chiral perturbation theory (chi PT). The data cover the resonance region, up to an invariant mass of W approximate to 1.9 GeV....
New results on the single-differential and fully integrated cross sections for the process gamma(upsilon)p -> p'pi(+)pi(-) are presented. The experimental data were collected with the CLAS detector at Jefferson Laboratory. Measurements...
Transverse momentum distributions and generalized parton distributions provide a comprehensive framework for the three-dimensional imaging of the nucleon and the nucleus experimentally using deeply virtual semi-exclusive and exclusive...
Despite decades of studies of the photoproduction of hyperons, both their production mechanisms and their spectra of excited states are still largely unknown. While the parity-violating weak decay of hyperons offers a means of measuring...
Short-range correlated (SRC) nucleon pairs are a vital part of the nucleus, accounting for almost all nucleons with momentum greater than the Fermi momentum (k(F)). A fundamental characteristic of SRC pairs is having large relative...
Beam-target double-spin asymmetries and target single-spin asymmetries in exclusive pi(+) and quasiexclusive pi(-) electroproduction were obtained from scattering of 1.6- to 5.7-GeV longitudinally polarized electrons from longitudinally...
Exclusive photoproduction cross sections have been measured for the process gamma p -> p pi degrees[e(+) e(-)(gamma)] with the Dalitz decay final state using tagged photon energies in the range of E-gamma = 1.275-5.425 GeV. The complete...
We present precision measurements of the target and beam-target spin asymmetries from neutral pion electroproduction in deep-inelastic scattering (DIS) using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. We scattered 6...
The cross section for coherent omega-meson photoproduction off the deuteron has been measured for the first time as a function of the momentum transfer t=(P-gamma - P-omega)(2) and photon energy E-gamma using the CLAS detector at the...
Results are presented for the first measurement of the double-polarization helicity asymmetry E for the eta photoproduction reaction gamma p -> eta p. Data were obtained using the FROzen Spin Target (FROST) with the CLAS spectrometer in...
Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive pi(+) electroproduction reaction. gamma(*) p -> n pi(+). The results were obtained from scattering of 6-GeV longitudinally polarized...
Measurement Of The Beam Asymmetry Sigma And The Target Asymmetry T In The Photoproduction Of Omega Mesons Off The Proton Using Clas At Jefferson Laboratory
The photoproduction of omega mesons off the proton has been studied in the reaction gamma p -> p omega using the CEBAF Large Acceptance Spectrometer (CLAS) and the frozen-spin target in Hall B at the Thomas Jefferson National Accelerator...
The exclusive reaction gamma p -> pK(+) K- was studied in the photon energy range 3.0-3.8 GeV and momentum transfer range 0.6 < -t < 1.3 GeV2. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator...
The f(0)(1500) meson resonance is one of several contenders to have significant mixing with the lightest glueball. This resonance is well established from several previous experiments. Here we present the first photoproduction data for...
Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive pi(0) electroproduction reaction. gamma(*) p -> p pi(0), expanding an analysis of the. gamma(*) p -> n pi(+) reaction from the same...
