  1. Tasks for the PrimEx • Finish the analysis process, fix the final numbers for the lpio ifetime. • Finish all 6 articles and have them published • Prepare the eta Primakoff experimental proposal for PAC34 (January, 2009) • Develop concept of the new HyCal-12 calorimeter for 12 GeV physics. Construct it before 2013 • Develop and prepare new pio run PrimEx-II at Hall B

  2. The PrimEx-II Experiment (E08-023) • The PrimEx goal is to reach 1.4% accuracy in 0 lifetime measurement. • Required to test the chiral anomaly in QCD and corrections to anomaly by different methods. • The PrimEx collaboration developed and constructed high precision experimental setup to perform this task in Hall B. • The 2004 run showed that the adapted Primakoff method and the experimental setup are capable of performing a percent level measurement of the 0 lifetime. • That was demonstrated by our current result and verified by the percent level extraction of two electromagnetic processes taken with high statistics. () = 7.93eV2.3%1.6% • The 2004 run, together with the commissioning of the new and complex experimental setup, did not provide high enough statistics in 0 to control the systematic errors in the experiment to reach the required precision: 1.4% in total error. 1.4% • PAC33 approved new PrimEx-II run with high statistics to control the systematic errors and reach the projected goal. • The CEBAF 6 GeV machine parameters are unique in reaching this precision. • The CEBAF 12 GeV beam will not provide the required accuracy for the PrimEx-II experiment.
