Top Quark Physics at the LHC == == [http://cdsagenda5.ictp.trieste.it/full_display.php?email=0&ida=a07179  Signaling the Arrival of the LHC Era] [[br]][[br]] Top Quark Physics at the LHC == === Authors === Decay * [:TopWidth:Top width]: Calculate the width of the top quark. * [:DeadCone:Radiation from heavy quarks]: the dead cone in %$e^+e^- \to Q \bar Q g$%. * [:TopDecaySpinCorrelations: W+ polarization in top decays]. * [wiki:TopWidth Top width]: Calculate the width of the top quark. * [wiki:DeadCone Radiation from heavy quarks]: the dead cone in $e^+e^- \to Q \bar Q g$. * [wiki:TopDecaySpinCorrelations W+ polarization in top decays]. Production * [:tt:top production] : %$t \bar t$% production and single top at Tevatron vs LHC. * [:scalar:scalar vs fermion top cross sections at hadron colliders] : Compare the production of scalar and fermion heavy color triplets in hadron collisions. * [:SpinCorr:Spin Correlations in top production] * [wiki:tt top production] : $t \bar t$ production and single top at Tevatron vs LHC. * [wiki:scalar scalar vs fermion top cross sections at hadron colliders] : Compare the production of scalar and fermion heavy color triplets in hadron collisions. * [wiki:SpinCorr Spin Correlations in top production] === Light material on the heaviest quark === * Look at the new physics models and check the particle and interactions content. * Generate events for a few selected processes and look at the plots: * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams. * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams. Analysis Tools * Importance sampling via an analytic transformation * Von Neumann's rejection method : plain and improved * Phase space for 1 -> n particles * Phase space for 1 -> n particles * Vegas * Top decay : comparison among the various methods * qq -> tt production * qq -> tt production All exercises are presented and solved this Mathematica Notebook: [attachment:mc101.http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/TAE2008/mc101.nb mc101.nb].
