USER Resources
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 !!!

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)

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.

Why EMC does not works for Charged Particles???
It is difficult to discriminate Pions (>90% of particles) from Kaons in the
Electromagnetic Calorimeter.Why?
James Cunha Werner [email protected]
Energy x Momentum from MC data
Detector Transfer Function change mass hyperboles!
James Cunha Werner [email protected]
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.

Goals of Pi0-roject
• Develop elementary programs and generate the documentation for future students.
• Study Pi0 annihilation and quarks interaction.
• Quark energy spectroscopy from energy histogram.
James Cunha Werner [email protected]
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 Pi0.
I am looking for partners to study Pi-zeros from Tau decays.
