Exploring the Structure of the Bound Proton with Deeply Virtual Compton Scattering Open
In the past two decades, deeply virtual Compton scattering of electrons has been successfully used to advance our knowledge of the partonic structure of the free proton and investigate correlations between the transverse position and the l…

Design and Operation of a Windowless Gas Target Internal to a Solenoidal Magnet for Use with a Megawatt Electron Beam Open
A windowless hydrogen gas target of nominal thickness $10^{19}$ cm$^{-2}$ is an essential component of the DarkLight experiment, which is designed to utilize the megawatt electron beam at an Energy Recovery Linac (ERL). The design of such …

Deeply Virtual Compton Scattering measurement off bound protons Open
We report the first beam spin asymmetry (BSA) measurement of incoherent deeply virtual Compton scattering (DVCS) off $^4$He. The data were accumulated using a 6 GeV longitudinally polarized electron beam incident on a pressurized $^4$He ga…

Measurement of unpolarized and polarized cross sections for deeply virtual Compton scattering on the proton at Jefferson Laboratory with CLAS Open
This paper reports the measurement of polarized and unpolarized cross sections for the ep→e′p′γ reaction, which is composed of deeply virtual Compton scattering (DVCS) and Bethe-Heitler (BH) processes, at an electron beam energy of 5.88 Ge…

Measurement of unpolarized semi-inclusive pi+ electroproduction off the proton Open
Semi-inclusive pi+ electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 GeV electron beam. The complete five-fold differential cross …

Q{sup 2} Dependence of Nuclear Transparency for Incoherent {rho}{sup 0} Electroproduction Open
Measurements of exclusive incoherent electroproduction of {rho}{sup 0} (770) meson from {sup 2}D, {sup 12}C, and {sup 63}Cu targets up to Q{sup 2} = 4 GeV{sup 2} are proposed using the CLAS detector. The objective of these measurements is …

Spectator-Tagged Deeply Virtual Compton Scattering on Light Nuclei Open
The three-dimensional picture of quarks and gluons in the proton is set to be revealed through Deeply virtual Compton scattering while a critically important puzzle in the one-dimensional picture remains, namely, the origins of the EMC eff…

Tagged EMC Measurements on Light Nuclei Open
We propose to measure tagged deep inelastic scattering from light nuclei (deuterium and $^4$He) by detecting the low energy nuclear spectator recoil (p, $^3$H and $^3$He) in addition to the scattered electron. The proposed experiment will …

Search for the Theta+ pentaquark in the gamma d -> Lambda n K+ reaction measured with CLAS Open
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, using the Hall-B tagged-photon beam of energy between 0.8 …
