1. MC/OFFLINE meeting  Status  Request by Ke2 group  aob LNF 09-12-2008

2. News (Hardware) fibm48 was born in September Immediately available for users Problems for kloerec: the names of the valid machines are hard-coded in datarec fixed in November

3. 2001, 2002 and off-peak data reprocessed with DBV-27 diff DBV-26 DBV-27 > twophselflt Twophselflt is the filter for gg physics it is OFF by default activated only in off-peak data reprocessing uic file see Capriotti, Nguyen, Venanzoni, KLOE Memo 346 News (data)

4. Old and unused mcr from old MC production scratched MC production with kpmke2 card only signal LSF = 250 Insertions in GEANFI: h  e + e - e + e - decay (only phase space) √s dependence in e + e -  a 1 p 0,wp 0  p + p - p + p - allrad production finally started on 04-12-2008 f decays excluded kaons and rp News (MC)

8. The Ke2 Quest's Request Ke2 people are craving 4TB NFS disks Ke2ers use already 4TB NFS disks, why do they want more space? 1-Their jobs are bottlenecked by disk access  more disks 2-They want to study some details in tracking and streaming  new ntuples  more space After new-vs-old ntuples comparison, old ntuples should be scratched freeing disk space (planned to be used as recalling areas) Tommaso will provide more details

9. More MC for 2004-2005, i.e. all_phys4 New MC for 2001-2002 with charged kaons background Dedicated production (if needed) MC production for KLOE-2 Others Offline Future

10. Backup slides

11. Difference between versions DBV-21Thickness of DC wall -75 mm Cut DC hits with drift times > 2.5 ms DBV-22EVCL to use HepDB values for p x (f) and √s Bugs fixed in minimum-bias radiative selection Small modification (resolutions, t 0 code) to neutral radiative stream Modifications to K S → p + p - p 0 tag; cuts loosened DBV-23Production of UFO Stream DBV-24Update efficiency parametrization for MC04/05 Some bugs fixed on DEDX and CELE and CSPS index DBV-25Use √s and x,y,z boost components in ppg selection Update dedx routine DBV-26Some work to fix KINE/cluster consistency Disable MC att len correction by default Add etappee selection DBV-27Add twophselflt Bug fixed in raw2dqce
