16. « Search for The charge asymmetry in top anti- top resonance » Smail Belaaouja (IFIC, Marcel Vos) Motivation :  QCD prediction: At tree level, tt~pair production at LHC is charge symmetric But at Ο(α s 3 ) 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 angle θ N tbar ( cosθ ): number of anti-top quark produced in an angleθ Valencia 18-19 November 201016

17. 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 « Search for The charge asymmetry in top anti- top resonance » Smail Belaaouja (IFIC, Marcel Vos)

18. Results :  Cut on the invariant mass with |  | < 1 (the asymetry is more importante) Valencia 18-19 November 201018 mtt > 500 GeVmtt > 700 GeVmtt > 1000 GeV Resonance : spin1 color singlet0.002350.002440.0016 Resonance : spin1 color octet-0.12-0.119-0.134  The values of the asymmetry depend on the cut on the invariant mass  Other resonances are being studied  Similar results obtained for the measured Results

19. Z’ → semi-leptonic channel Zineb El Mouridi (LPC) Valencia 18-19 November 201019  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 : Reconstructed mass distribution and truth mass distribution for Z’ studied samples (500 GeV, to 3TeV) with an additional jet added if found
