  1. Some Aspects of Deeply Virtual Compton Scattering

    Kuchina, Elena2019

    <p>We consider different aspects of the virtual Compton amplitude in QCD on two examples: small-x physics accessible in the Regge regime and twist-3 approximation in the description of DVCS through the general parton distributions. Using this model, we give an estimate for the cross section of …

  2. Virtual Compton Scattering Processes in Quantum Chromodynamics

    Musatov, Igor V.2019

    <p>Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive meson electroproduction processes require a generalization of usual Parton distributions for the case when long-distance information is accumulated in nonforward matrix elements [special characters omitted] …

  3. Beam spin asymmetry measurements in deeply virtual Compton scattering

    Gavalian, Gagik

    … Spin Asymmetry (BSA) is studied in the Deeply Virtual Compton Scattering (DVCS) using CLAS detector at Jefferson Lab and longitudinally polarized electron beam with 4.8 GeV energy. This asymmetry is directly proportional to the imaginary part of the scattering amplitude, which relates it to the …

    Hashir Rashad, Mohamed Nuhman2021

    … of constituents of a quark-gluon system. Deeply Virtual Compton Scattering (DVCS) is understood to be the simplest and cleanest process to access GPDs. Even though the exclusive DVCS is simple to understand, the experimental process however, is complex with the Bethe-Heitler and Associated DVCS …

  5. Deeply Virtual Compton Scattering off unpolarised deuterium at HERMES

    Hill, Gordon DUniversity of Glasgow2008

    … HERMES focused on measurements of the Deeply Virtual Compton Scattering (DVCS) process. These measurements are sensitive to GPDs, allowing further experimental constraints to be made on the components of nucleon spin. In the Winter shutdown period 2005-2006 HERMES was upgraded with a Recoil …

  8. MEASUREMENT OF THE GENERALIZED POLARIZABILITIES OF THE PROTON IN VIRTUAL COMPTON SCATTERING

    Li, RuonanTemple University. Libraries2022

    … GPs can be accessed through measurements of the Virtual Compton Scattering reaction, by replacing the incoming real photon of the Compton scattering process with a space-like virtual photon. The outgoing real photon provides the EM perturbation to the system. In addition, the Dispersion Relation …

  9. Measurement of Virtual Compton Scattering Below Pion Threshold at Invariant Four-Momentum Transfer Squared Q²=1.(GEV/C)²

    Jutier, Christopher2019

    <p>Experimental Virtual Compton Scattering (VCS) off the proton is a new tool to access the Generalized Polarizabilities (GPs) of the proton that parameterize the response of the proton to an electromagnetic perturbation. The Q<sup>2</sup> dependence of the GPs leads, by Fourier transform, to a …

  10. Measurement of the Deeply Virtual Compton Scattering Cross Section from the Proton at 10.6 GeV using the CLAS12 Detector

    Lee, SangbaekMassachusetts Institute of Technology2022

    Deeply Virtual Compton Scattering (DVCS) is an exclusive process that produces a real photon when a lepton scatters from a quark inside a nucleon or a nucleus. Measurement of the DVCS cross section enables the study of the Generalized Parton Distributions (GPD), which plays a central role in …

  11. Measurement of the Deeply Virtual Neutral Pion Electroproduction Cross Section off the Proton at 10.6 GeV using the CLAS12 Detector

    Johnston, RobertMassachusetts Institute of Technology2023

    Deeply virtual exclusive reactions provide unique channels to study both transverse and longitudinal properties of the nucleon simultaneously, allowing for a 3D image of nucleon substructure. This presentation will discuss work towards extracting an absolute cross section for one such exclusive …

  12. Inclusive and Exclusive Compton Processes in Quantum Chromodynamics

    Psaker, A.2019

    <p>In our work, we describe two types of Compton processes. As an example of an inclusive process, we consider the high-energy photoproduction of massive muon pairs off the nucleon. We analyze the process in the framework of the QCD parton model, in which the usual parton distributions emerge as a …
