Ma. Grid tutorial The team has organised a national grid tutorial in the Faculty of Rabat, on 13 th 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
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 60 Gbites) 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
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
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 Ge. V 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
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
Main physics topics 3 - ECAL of Calice Thesis 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
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
