     31The UFO provided together with the feynrules model file was generated for four flavour scheme (4FS) calculations. To perform 5FS ones, you need to generate a new UFO by loading massless_5f restriction file instead of massless_4f. 
     32 
     33Below we give the MadGraph syntax used to generate various mono-X signals

     43Massive top and bottom quarks. 4FS calculation. 
     44This is LO as there are no tree level diagrams in this scheme. 
     45 
     46=== MONO-H ===

     52 
     53 
     54Same notes as above.

     56=== MONO-Z ===

     62 
     63 
     64Same notes as above. 
     65 
     66=== MONO-W === 
     67 
     68WARNING: needs 5FS UFO! 
     69 
     70 
     71{{{ 
     72generate p p > w+ ~xd ~xd~ [QCD] 
     73}}} 
     74 
     75 
     76This has not been tested.  
     77This is LO as there are no tree level diagrams in this scheme. 
     78 
     79=== TT+MET (tree level) === 
     80 
     81 
     82{{{

     98 
     99=== TT+MET (NLO) ===

     101Not working yet. However you can generate

     103 
     104{{{ 
     105generate p p > t t~ S1 [QCD] 
     106

     108}}} 
     109 
     110 
     111Massive top and bottom quarks. 4FS calculation. 
     112This is NLO accurate result including both top and bottom loops. 
     113 
     114=== BB+MET (NLO) === 
     115 
     116same as above. 
     117 
     118=== DI-JET+MET === 
     119 
     120WARNING: to make 5FS you need to output a new UFO with the right restrictions 
     121 
     122 
     123{{{ 
     124generate p p > j j ~xd ~xd~ [QCD] 
     125}}} 
     126 
     127 
     128Massive top and bottom quarks. 4FS calculation. 
     129This is LO as there are no tree level diagrams in this scheme. 
     130 
     131To use 5FS, you need to generate a new UFO output by loading massless_5f restriction file instead of massless_4f.
