The model allows the computation of (pseudo-)scalar resonance production in top-antitop quarks final state at NLO in QCD accuracy, including interference effects.


To use the model in MadGraph_aMC@NLO you need to follow these instructions: 1 - comment line self['loop_diagrams']=newloopselection in madgraph/loop/ inside your distribution 2 - generate the output with > import model AHttbar >define p = 21 2 4 1 3 -2 -4 -1 -3 5 -5 >define j = p >set complex_mass_scheme >generate p p > t t~ QCD=2 QED=1 EFT=1 [QCD] >output PROC_pp-tt 3 - go into the generated directory (e.g. PROC_pp-tt) and comment the following lines in SubProcesses/montecarlocounter.fc write(*,*)'Error #4 in set_matrices' c write(*,*)isspecial0,nglu,nsngl c stop c write(*,*)'Error #6 in check_mc_matrices', c # notagluon,ntot,max_bcol c stop 4 - modify cards according to your needs and generate events using standard commands. SM QCD background, signal and interference will be generated on the same sample.
