Title: Differential cross section for γd → ωd using CLAS at Jefferson Lab

Abstract

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 Thomas Jefferson National Accelerator Facility. The cross sections are measured in the energy range 1.4 < E-gamma < 3.4GeV. A model based on omega- N rescattering is consistent with the data at low and intermediate momentum transfer, vertical bar t vertical bar. For 2.8 < E-gamma < 3.4GeV, the total cross-section of omega - N scattering, based on fits within the framework of the Vector Meson Dominance model, is in the range of 30-40 mb.

Measurement of the beam asymmetry $Σ$ and the target asymmetry $T$ in the photoproduction of $ω$ mesons off the proton using CLAS at Jefferson Laboratory

Journal Article Roy, P. ; Akbar, Z. ; Park, S. ; ... - Physical Review C

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 Facility. For the first time, the target asymmetry T has been measured in photoproduction from the decay omega -> pi(+)pi(-)pi(0), using a transversely polarized target with energies ranging from just above the reaction threshold up to 2.8 GeV. Significant nonzero values are observed for these asymmetries, reaching about 30-40% in the third-resonance region. New measurements for the photon-beam asymmetry Sigma aremore »« less

Measurement of coherent {phi}-meson photoproduction from the deuteron at low energies

The cross section and decay angular distributions for the coherent {phi}-meson photoproduction on the deuteron have been measured for the first time up to a squared four-momentum transfer t=(p{sub {gamma}}-p{sub {phi}}){sup 2}=-2 GeV{sup 2}/c{sup 2}, using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cross sections are compared with predictions from a rescattering model. In a framework of vector meson dominance, the data are consistent with the total {phi}-N cross section {sigma}{sub {phi}}{sub N} at about 10 mb. If vector meson dominance is violated, a larger {sigma}{sub {phi}}{sub N} is possible by introducing a larger t slopemore »« less

Mesons in the medium: Experiments with CLAS at Jefferson Lab

Conference Michael Wood, Rakhsha Nasseripour, Michael Paolone, Chaden Djalali, Dennis Weygand - Int.J.Mod.Phys.A

In this article, we report on on investigations of the in-medium meson-nucleon interaction for the omega, phi, and K^0_s mesons. Their in-medium cross sections and collisional widths can be measured by their absorption in a nucleus. In Hall B at the Thomas Jefferson National Accelerator Facility (JLab), the CLAS detector was used to study these long-lived mesons in nuclei. All of the mesons were produced by a photon beam with Egamma < 4 GeV in targets of 2H, C, Fe, and Pb. The vector mesons were reconstructed through their decay into e+e-. The K^0_s mesons were measured with their dominantmore »« less

Measurement of polarization observables in vector meson photoproduction using a transversely-polarized frozen-spin target and polarized photons at CLAS, Jefferson Lab

Thesis/Dissertation Roy, Priyashree

The study of baryon resonances provides a deeper understanding of the strong interaction because the dynamics and relevant degrees of freedom hidden within them are re ected by the properties of the excited states of baryons. Higher-lying excited states at and above 1.7 GeV/c² are generally predicted to have strong couplings to final states involving a heavier meson, e. g. one of the vector mesons, ρ, ω φ, as compared to a lighter pseudoscalar meson, e. g. π and η. Decays to the ππΝ final states via πΔ also become more important through the population of intermediate resonances. We observe that nature invests in mass rather than momentum. The excited states of the nucleon are usually found as broadly overlapping resonances which may decay into a multitude of final states involving mesons and baryons. Polarization observables make it possible to isolate single resonance contributions from other interference terms. The CLAS g9 (FROST) experiment, as part of the N* spectroscopy program at Jefferson Laboratory, accumulated photoproduction data using circularly- & linearly-polarized photons incident on a transversely-polarized butanol target (g9b experiment) in the photon energy range 0:3-2:4 GeV & 0:7-2:1 GeV, respectively. In this work, the analysis of reactions and polarization observables which involve two charged pions, either in the fully exclusive reaction γρ -> ρπ+π- or in the semi-exclusive reaction with a missing neutral pion, γρ -> ρπ⁺π^-(π⁰) will be presented. For the reaction ρπ⁺π^-, eight polarization observables (I^s, I^c, P_x, P_y,more »« less
