2 News:  MC04  all LSF=1 completed (~535 pb -1 )  mrc dst of 2005 with correct   +  - e + e - ~completed (1.13 fb -1 done, 95%).  MC all_phys2 (dtr_gb_nr=1) started for 2004 data: 400 pb done in ~15 days, 26pb -1 /day  New request (P. Beltrame): production of 250 pb -1 Bhabha at 1 GeV,  =420 nb, LSF = 2. Estimate rate 60pb -1 /day, 1 week to complete.  “Organizational” news: R. Versaci deputy convener

Production completed in ~4 months of running, average rate 18 pb -1 /day. The inefficiency for K ± dst’s mostly caused by the 2GB limit for single file. They will be recovered in future. Production of ~1.2 fb -1 (2005 data) of: K ± rare decays (K ±  e, , e ), K S rare decays (K S  e, ,  e, , 3  K L rare decays (K L , ,  e,  e,  Production completed in 8 days of running. Production of 240 pb 1GeV of:  ( e + e -  ),  =50 nb, LSF=6  ( e + e -  ),  =30 nb, LSF=6 Production completed in 5 days of running.

4 Status of reconstruction at Sep 07 DBV ScanComment bad wires ! 215 Various significant ECL mods Minor changes to recon No bias sample for rad Stable ECL Old bias sample for rad Stable ECL for  s = m f ufo as bias sample Stable ECL for off-peak ufo as bias sample Stable ECL for off-peak ufo as bias sample analyzed Fully cal trgmon luminosity in pb -1 by year and DBV First 125 pb -1 of 2004 show large time jitter. We will reprocess if needed. OK Don’t have   +  - e + e - selection. We want to reprocess them

5 Short term activities:  Duplicate MC04/05  all statistics (~1.7 fb -1 ) ~120 days (started)  Reprocessing of 2005 data with DBV<25: ~80 days (1.1 fb -1 )  Dst’s holes  Rad MC LSF = 5: ~10 days  Beltrame’s request: 250pb -1 of Bhabha at 1 GeV (~1 week) Within this schedule we should be able to finish this activity in ~7 months from now (i.e. March 08)
