Summary of Meeting Discussions:

All. Nominate secretary: (next secretary: Pawel)

All. Approval of last meeting's minutes:

Approved. Remind Dustin and Vasily to write a short notes on HYCAL cluster algorithm. Time walk correction in HyCal is suggested to be included in HYCAL paper.

All. New Business: Itemized below

3: Analysis note review status (Eugene):

All new analysis notes are posted and linked through the secure Wiki
  Dan posted his comments to Pawel (on secure Wiki) . Mark will scan his comments on Compton and post it on Wiki.

4: : Calculation of the incoherent cross section: Sergey
 presentation

Sergey included rescattering correction in his incoherent calculation. After correcting some errors in Tulio's calculation, Sergey and Tulio come to agreement on the incoherent nuclear cross section.

5: Pion0 analysis with the lead target: Ilya
 presentation

Ilya showed his new results Pb. The pion0  lifetime on C and Pb are very consistent within the error bar. Ilya also pointed out the different tdiff behaviors between the PbWO4 and lead glass. Further  studys on this issue for future runs are needed.

6:  Changes in efficiency with a dead dynode in the total sum, simulation. by Eric

 presentation

Eric studied the trigger efficiency with dead dynodes in the total sum. He concluded that there is no significant effect on the trigger efficiency from dead dynodes.
