Abstract
In order to try to settle the question of the origin of the EMC effect, experiments will be performed to study polarized EMC effects at Hall B at Thomas Jefferson National Accelerator Facility (JLab).
They will use longitudinally polarized 11 GeV electron beams and longitudinally polarized $^7$LiD and NH$_3$ targets with CLAS12 detectors.
JLab target and collaborating groups (Hall B group, engineering and accelerator divisions) are preparing an irradiation beam line, designing and constructing irradiation and DNP (Dynamic Nuclear Polarization) polarizing cryostats.

Metadata are provided both in
article format (very
similar to INSPIRE)
as this helps creating very compact bibliographies which
can be beneficial to authors and readers, and in
proceeding format which
is more detailed and complete.
