[Eg6_analysis] DNP meeting in Santa Fe

[Sylvester Joosten]

Hi everyone,

Below you can find a draft of my abstract. Please let me know if you have
any suggestions.

Cheers,
Sylvester

The European Muon Collaboration (EMC) observed the first signs of a
modification of the partonic structure of the nucleon when present in a
nuclear medium. The precise nature of these effects, as well as their
underlying cause, is yet to be determined. The generalized parton
distribution (GPD) framework provides a powerful tool to study the partonic
structure of nucleons inside a nucleus, as it encodes a multidimensional
representation of the nucleon structure at the partonic level.

Hard exclusive leptoproduction of a real photon off a nucleon, deeply
virtual Compton scattering (DVCS), is presently considered to allow for the
cleanest experimental access to the GPDs through the related Compton form
factors (CFFs). This is especially the case for scattering off a helium
nucleus, where only a single CFF contributes to the process due to its zero
spin. The real and imaginary parts of this CFF can be constrained through a
measurement of the beam-spin asymmetry (BSA).

We will present the first measurements of the DVCS process off 4He using
the 6 GeV polarized electron beam of the Thomas Jefferson National
Accelerator Facility and the CLAS detector in the experimental Hall B. For
these measurements, the CLAS detector was supplemented with an inner
electromagnetic calorimeter for photons produced at small angles, as well
as a radial time projection chamber (RTPC) to detect low-energy recoil
nuclei. This setup allowed a clean measurement of the BSA in both the
coherent and the incoherent channels.
