"The GlueX Program at Hall D"
Yi Qiang
Jefferson Lab
Abstract: As part of Jefferson Lab’s 12 GeV upgrade, the new experimental
Hall-D is currently under installation. Hall-D will use the electron beam
to produce a linearly polarized Bremstrahlung photon beam and house a
solenoid-based hermetic detector. By using such a setup, Hall-D’s flagship
GlueX experiment will be able to provide critical photoproduction data to
help understand the soft gluonic field responsible for binding quarks in
hadrons. Hybrid mesons, and in particular exotic hybrid mesons, provide the
ideal laboratory for testing QCD in the confinement regime since these mesons
explicitly manifest the gluonic degrees of freedom. Photoproduction is expected
to be particularly effective in producing exotic hybrids but there is little
data on the photoproduction of light mesons. This talk will give an update on
Hall-D's status, describe the latest theoretical developments to help understand
how the data of hybrid mesons can provide insights into the fundamental theory
of strong interactions. Some highlights of other future Hall-D projects will be
presented as well.
