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.
