Our postdoctoral associate Akihisa Shinozaki and two Ph.D. students, Yuan Xiao and Chi Zhang, have already embarked on this project. We anticipate that this process, culminating in two dissertations and journal publications, will take up to 2 years. JLab Programs The analysis of the data related to the search of the pentaquark partners in Hall A is near completion. The results are being finalized and are being presented already in conferences, including by our student Yi Qiang. Most of the remaining time in year 2006 will be devoted to the writing of the dissertation. Production of a preliminary draft manuscript intended for Physical Review Letters has been already initiated and will be completed soon. The analysis of the data related to the short-range structure of nuclei has just begun. Since the experiment was performed in conjunction with the commissioning of the Bigbite spectrometer and the new neutron-detector wall, effort must be devoted towards optimizing the operational/analysis constants (e.g. time-corrections, optics, thresholds etc.) of these devices. This process has already begun in parallel to developing the physics algorithms for the data analysis. We expect very preliminary results to be presented at conferences within a few months, and the completion of the analysis leading to theses and journal publications in about 1-2 years. One of our students, Peter Monaghan, devotes his time to this analysis, assisted by our JLab postdoctoral associate. Much of our activity in 2006 is devoted to measurements of the neutron electromagnetic form factors. We are providing over one FTE (combined efforts of our JLAB postdoctoral associate and one Israeli visiting scientist) contribution to the currently running experiment E02-013,  in Hall A, which will provide data on the neutron electric form factor GEn at momentum transfers up to 3.5 (GeV/c)2. This experiment will be completed in May 2006. Our near term activities will be focused on approved new experiments, two of which were proposed by NIG members. There are no graduate students assigned to these experiments yet, although we expect that the physics of these two experiments will be sufficient for 2~3 Ph.D. theses. In particular, E05-102 is scheduled to run in last 2007-2008. Involvement in this experiment will include both analysis and hardware trainings like working on the polarized 3He target.

An overview of the physics can be found at the ANL/MEP PV-DIS page. It is likely to run in late 2008-2009, but so far there is no graduate student assigned to this experiment. The experiment will provide physics for 1~2 Ph.D. thesis, and because it requires upgrades of the Compton Polarimeter and the data aquisition system in Hall A, it will provide good opportunity for hardware/instrumentational trainings.

Efforts have already started in preparation for the measurement of the electric to magnetic form factors ratios for the proton, GEp/GMp, up to transferred momentum of 9 (GeV/c) in Hall C (E04-108). This experiment requires the development of major equipment and is anticipated to run late 2006 or 2007. One of our graduate students, Andrew Puckett, has selected this experiment for his thesis. Accordingly, both he and our group are going to devote much effort in the coming years to this experiment. Lastly, we will continue proposing new experiments and ideas to the JLab nuclear physics community. For example, we are planning to re-present our deferred proposal, PR05-010 [study of the Roper (1440) resonance using the double-polarization p(e,e'p)pi0 reaction in Hall A using a polarized beam and a focal plane polarimeter]. As mentioned, this proposal was deferred pending a laboratory-wide coordination for the purpose of studying the Roper (1440) resonance. As part of this coordination effort, we are organizing a workshop on the Roper (1440) resonance to take place during the next Jefferson Laboratory's Users Group meeting. Following this workshop, we are planning to re-submit the proposal (albeit with modifications required by the outcome of the workshop) to future sessions of the PAC.
