I have a letter of intent to measure the parity and spin
of the exotic $\Theta^+$ state using a circularly polarized photon
beam and a polarized 3He Target in
Hall A. This LOI has been submitted to JLab
PAC-25.
The submission version can be found here:
PDF,
PS. But please do keep in
mind that the main purpose of this LOI is to provide the basic idea,
we have changed most of the experimental design since submission.
