- Schedule of presentations
- Other Studies:
- A summary of rho beam asymmetry data Curtis
- Curtis prepared a document compiling the world data on the Sigma beam asymmetry for rho photoproduction.
- The uncertainties on these previous measurements are large and, as expected, aren't usable for absolute polarization normalization.
- Beam Polarization: Justin, Mike, Nathan, Richard
- The beam asymmetry observed for low energy rho production remains an open question
- Richard is looking into alternative explanations for low energy polarization, and possible improvements on the assumption used in the literature
- Ken L. added (by e-mail) that beam asymmetries using coherent bremstrahlung and laser backscattering at lower energy show good agreement, which provides some additional confidence in the CBSA method for the coherent peak region
- Note: As requested the model used for the CBSA fits is CLAS Note 2011-20 by Ken L., where the parameters in the fit are defined at the end of Sec 2 (pg 7).
- Studies are ongoing to include the tagger coincidence in the TPOL asymmetry results
- The beam asymmetry observed for low energy rho production remains an open question
- A summary of rho beam asymmetry data Curtis
- Analysis Launch Preparations:
- Plugin Requirements
- EventStore Readiness: Sean
- Work is ongoing to utilize Richard's update the HDDM interface in EventStore.
