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

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

Only Pions James Cunha Werner jamwer@hep. man. ac. uk

Only Kaons James Cunha Werner jamwer@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. Tau 11 80, 000 events of 440, 000. James Cunha Werner jamwer@hep. man. ac. uk

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