1. James Cunha Wernerjamwer@hep.man.ac.uk Job Submission for Babar Analysis James Werner Resources: www.hep.man.ac.uk/u/jamwer

2. James Cunha Wernerjamwer@hep.man.ac.uk USERResources Reliable. Robust. Efficient. Optimal use of resources. Recover from fail conditions. Supply clear information about crashes. The ideal Job Submission System is the one users do not know it exists !!!

3. James Cunha Wernerjamwer@hep.man.ac.uk Analysis Job Submission

4. James Cunha Wernerjamwer@hep.man.ac.uk Matching MC with experiment 18,700,000 events!

5. James Cunha Wernerjamwer@hep.man.ac.uk Analysis Submission to Grid Single command:./easygrid dataset_name Perform Handlers management and submission Software based in State-machine –Verify skimdata available: If not available perform BbkDatasetTCL to generate skimData. Each file will be a job. –Verify if there are handlers pending If not, script generation (gera.c) with edg-job-submit and ClassAdds, and script execution. Nest for submission policy and optimisation. If yes, verify job status. When the all jobs ended, recover results in user folder. (Prototype)

9. James Cunha Wernerjamwer@hep.man.ac.uk Event Reconstruction using Monte Carlo simulation Obtain instable particles from combination of stables particles measured by Babar detector/MC. Recursive algorithm, easy to use and recurrent. The “background” effect due wrong combinations.

10. James Cunha Wernerjamwer@hep.man.ac.uk Combination 2 particles/gammas Monte Carlo“Experiment”

11. James Cunha Wernerjamwer@hep.man.ac.uk Combination 3 particles/gammas Monte Carlo“Experiment”

12. James Cunha Wernerjamwer@hep.man.ac.uk Combination 4 particles/gammas Monte Carlo “Experiment”

13. James Cunha Wernerjamwer@hep.man.ac.uk Event Reconstruction from Experimental data Pi 0 !

14. James Cunha Wernerjamwer@hep.man.ac.uk 80,000,000 events !!! Pi 0

15. James Cunha Wernerjamwer@hep.man.ac.uk Why EMC does not works for Charged Particles??? It is difficult to discriminate Pions (>90% of particles) from Kaons in the Electromagnetic Calorimeter. Why?

16. James Cunha Wernerjamwer@hep.man.ac.uk Energy x Momentum from MC data Detector Transfer Function change mass hyperboles!

17. James Cunha Wernerjamwer@hep.man.ac.uk Only Pions

18. James Cunha Wernerjamwer@hep.man.ac.uk Only Kaons

19. James Cunha Wernerjamwer@hep.man.ac.uk Could Artificial Intelligence… Obtain a non-linear discriminate function able to classify kaons / pions? Recover “not good” events (80% of the Database)? e.g. Tau11 80,000,000 events of 440,000,000.

21. James Cunha Wernerjamwer@hep.man.ac.uk Goals of Pi 0 -roject Develop elementary programs and generate the documentation for future students. Study Pi 0 annihilation and quarks interaction. Quark energy spectroscopy from energy histogram.

22. James Cunha Wernerjamwer@hep.man.ac.uk My goals are… develop a submission system fail proof. write web pages with all elementary tasks in HEP/Babar, to help students and newbie. Understand q-qbar interaction through Pi 0. I am looking for partners to study Pi-zeros from Tau decays.
