8 RUPHE (Réseau Universitaire des Hautes Energies -Morocco) 1996 : Morocco joined ATLAS experiment RUPHE : Moroccan High Energy Physics Network - 5 Universities: Rabat, Casablanca, Marrakech, Oujda, Tanger - CNESTEN (the National Center for Energy, Science and Nuclear Technics) 8

9 Morocco in ATLAS Participation to the ATLAS electromagnetic presampler construction anode 1 Module 64 sectors (8 modules / sector) = 512 modules (50000 anodes ) Mechanical and electrical test of anodes Rabat and Casablanca 1 sector 9

10 Morocco in ATLAS the insertion of 32 sectors of the presampler at CERN. 10

11 Morocco in ATLAS Physics and detector simulations Test beam (shifts, assembling, insertion, ) at CERN Analysis of combined test beam data Simulated and Real Data Analysis 11

12 Collaboration with France LPSC (Grenoble)/ Science University (Rabat and Casablanca : Integrated Action (AI) ( ) CPPM Marseille/ Science University Oujda: PICS ( ) GDRI (International Research Group ) ( ) LIA (International Associate Laboratory ) named «ILCP: International Laboratory for Collider Physics» ( ) 12

13 Collaboration with Spain the 2007MA0057 Project between the CNRST and CSIC PCI2009 ( A/023372/09) project between University of Valencia and Mohammed V Agdal University An agreement for a convention between these 2 universities will soon be established An Integrated Action in the futur 13

14 PHD Theses in Rabat (ATLAS) «Etude des performances du Pre-Echantillonneur Central d'atlas», Younouss EL MOUAHHIDIN, soutenue le 14 mars «Une possibilité de déterminer la fonction de structure du gluon dans l expérience ATLAS en utilisant la section efficace - jet dans les collisions pp à = 14 TeV au LHC», El Mamoun ABOUELOUAFA, soutenue le 14 mars 2002 «Search for The charge asymmetry in top anti-top resonance» Smail Belaaouja «Prospects for Z Search using the Z tt semi-leptonic channel» Zineb El Mouridi 14

15 Some other Theses throughout Morocco Study of the Top Quark Properties & Effect of New Physics Sara Boutouil (LPC&CERN /Oujda) Observation of Bd->Jpsi(mu,mu) Ks(pipi) resonance in ATLAS and Crosstalk correction - Mohamed Gouighri (CERN/Casablanca) Measurement of the Higgs mass & analog vs. digital energy reconstruction in the Si-W ECAL for ILC - Youssef Khoulaki (Casablanca/Grenoble) Studying New Gauge Boson Z in di-leptonic Channel and the Electronic calibration system of the Electromagnetic Calorimeter at ATLAS - Said Lablak (Casablanca) Phenomenology of Higgs triplet model - Larbi Rahili (Tanger/Montpellier) 15

16 «Search for The charge asymmetry in top antitop resonance» Smail Belaaouja (IFIC, Marcel Vos) Motivation : QCD prediction: At tree level, tt~pair production at LHC is charge symmetric But at Ο(α s3 ) order tt~ pair production is a charge asymmetic Definition The charge asymmetricy is defined as: N t (cosθ): number of top quark produced in an angleθ N tbar (cosθ): number of anti-top quark produced in an angleθ 16

17 «Search for The charge asymmetry in top antitop resonance» Smail Belaaouja (IFIC, Marcel Vos) Model: The top quark charge asymmetry Beyond the SM at the LHC (topbsm) This model includes a number of intermediate resonances states that decay into ttbar: The topbsm is implemented to study effects in the ttbar invariant mass spectrum Possible resonances studied in the ttbar spectrum : a spin1 color singlet (similar to the SM Z boson) a spin1 color octet (similar to a heavy gluon) Process: Tool : MadGraph Generator

18 «Search for The charge asymmetry in top antitop resonance» Smail Belaaouja (IFIC, Marcel Vos) Results : Cut on the invariant mass with < 1 (the asymetry is more importante) A tt mtt > 500 GeV mtt > 700 GeV mtt > 1000 GeV Resonance : spin1 color singlet Results Resonance : spin1 color octet Similar results obtained for the measured A The values of the asymmetry depend on the cut on the invariant mass Other resonances are being studied m tt 18

19 Z tt semi-leptonic channel Zineb El Mouridi (LPC) The aim: Reconstruct the ttbar spectrum to measure the ATLAS sensitivity for a Z resonance creation (Beyond SM) ttbar decay mode : semi leptonic Comparison between : tt Reconstructed mass distribution and truth tt mass distribution for Z studied samples (500 GeV, to 3TeV) with an additional jet added if found 19

20 New researches Medical Physics (in Rabat and Oujda) - Simulation with GEANT4 and GATE (scanner, accelerator) in radiology, nuclear medicine, radiotherapy Conception and design of Detector in the International Linear Collider (ILC) (In Casablanca) 20
