  1. prepared and revised by : Bouchra Belhorma & Mourad Belmir : Centre National de l'Energie, des Sciences et des Techniques Nucléaires, Rabat Rajaa Cherkaoui El Moursli & Zineb Elmouridi : Faculty of Science, Mohammed V-Agdal University, Rabat Yahya Tayalati & Mohammed Hamel : Faculté polydisciplinaire de Nador, Université Mohammed Ier d'Oujda Presented by : Farida Fassi for the Moroccan team Physic topics and MaGrid

  2. Plan • Present Grid usages • Used/needed packages • MaGrid tutorial • Magrid site status • Main physic topics for the Moroccan members • Perspectives

  3. Present Grid usages • ATLAS • Calice/ILC • Medical physics

  4. Used/needed packages1- ATLAS • Athena • Geant4 • Ganga/panda • DQ2 Users : all RUPHE members Ruphe : Réseau Universitaire de la Physique des Hautes Energies

  5. Used/needed packages2- CALICE-ILC • Mokka • Marlin Users : B. Belhorma, M. Belmir, Y. Tayalati, M. Hamel

  6. Used/needed packages3- MEDICAL PHYSICS • Gate Users : Y. Tayalati, R. Cherkaoui

  7. MaGrid tutorial The team has organised a national grid tutorial in the Faculty of Rabat, on 13th June 2008; 20 participants of different profiles (teachers and students) reached this workshop. http://tutorial-grid.fsr.ac.ma A temporary grid UI has been installed and used for the tutorial. The official Magrid UI was shutdown due to the site change of CNRST

  8. Magrid site status • Regular EVO meetings are organised between Moroccan team in order to follow the setup of the site. Athena 14.2.10 is installed and tested OK • In progress : a complete (about 60Gbites) CERN software mirror will be installed • In a second phase, the packages for Calice will be installed, as well as Gate for medical physics simulations

  9. Main physic topics for the Moroccan members • in ATLAS top quark physics • in Calice testbeam data analysis • In medical physics : PET tomography simulations • Linear accelerator • Brachytherapy

  10. Main physics topics 1- Top mass reconstruction in the semi-leptonic mode Thesis of Z. Elmouridi, codirected by Rajaa Cherkaoui El Moursli (University of Rabat) and Dominique Pallin (Laboratoire de Physique Corpusculaire de Clermont-Ferrand) Events reconstruction for Mt=175 GeV t  W(jj)b and t  W(lv)b 1- Comparison of different reconstruction algorithms for MC generated events 2- MC generation by Z’->ttbar with various Z’ energies 3- Events Reconstruction and analysis

  11. Main physics topics 2- Top quark study in the full hadronic ttbar channel Y. Tayalati Study of the jet reconstruction. The ttbar data are generated by MC@NLO available on the ATLAS grid. Study of the cone, Kt and Yspliter algorithms

  12. Main physics topics 3- ECAL of CaliceThesis of M. Belmir In collaboration with LPSC-Grenoble Electromagnetic Calorimeter testbeam analysis of data taken in DESY and CERN (2006-2007) and Fermilab (2008): energy resolution, uniformity and linearity; position resolution; corrections of guard rings effects

  13. Perspectives • Projet d’Action intégrée entre les Universités de Rabat et d’Oujda, CNESTEN, l’Institut de Physique Corpusculaire de Valencia et le Laboratoire de Physique Corpusculaire de Clermont-Ferrand • two main topics in ATLAS : Higgs and top physics • Medical Physics : PET tomography • Ecal/Calice : testbeam analysis • Evolution of Magrid to a tier 3 in under discussion • Installation of clusters in other universities (Rabat, Oujda) • 3 new students planned from 2009
