First Measurement of Deeply Virtual Compton Scattering on the Neutron with Detection of the Active Neutron
Measuring Deeply Virtual Compton Scattering on the neutron is one of the
necessary steps to understand the structure of the nucleon in terms of
Generalized Parton Distributions (GPDs). Neutron targets play a complementary
role to transversely polarized proton targets in the determination of the GPD
$E$. This poorly known and poorly constrained GPD is essential to obtain the
contribution of the quarks' angular momentum to the spin of the nucleon. DVCS
on the neutron was measured for the first time selecting the exclusive final
state by detecting the neutron, using the Jefferson Lab longitudinally
polarized electron beam, with energies up to 10.6 GeV, and the CLAS12 detector.
The extracted beam-spin asymmetries, combined with DVCS observables measured on
the proton, allow a clean quark-flavor separation of the imaginary parts of the
GPDs $H$ and $E$.
