My work as a Diploma student was done in collaboration with the Thomas Jefferson Laboratories (JLAB), Newport News, VA. At JLAB is active the CEBAF (Continuous Electron Beam Accelerator Facility), which is a double LINAC connected by recirculation arcs able to provide an almost continuous polarized electron beam, up to an energy of ~6GeV.
In particular, I worked with the CLAS (CEBAF Large Acceptance Spectrometer) detector, which is particularly suited to reconstruct complete final states and exclusive reactions.
I studied the target spin asymmetry in the exclusive reaction:

which is nonzero and can be computed using the generalised partonic distributions (GPD).
A short description of my work can be found in my thesis or in Hall-B secure page (password protected).
I'm now involved in the construction of a quasi-real photon tagger for CLAS12. |
