8 | | To use the model in MadGraph_aMC@NLO you need to follow these instructions: |
9 | | 1 - comment line self['loop_diagrams']=newloopselection in madgraph/loop/loop_diagram_generation.py inside your distribution |
10 | | 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 |
11 | | 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. |
12 | | 4 - In the parameter card, the lambda, yht, yht5, ctg, cphig, cphig5 correspond to the coefficients in eq.3.12; yhf and yhf5 are not used by the model; muprime and muyukawa are the (MSbar) scales at which the operator coefficients and the yht/yht5 are defined respectively; creal + i*cimag is the adhoc phase we had to add to all operators for reweighting purpose; cc is an overall coefficient that is multiplied to all operators (so that you can set cc=+x and cc=-x and subtract the two samples to get the pure interference.) |
