Charge Conjugated process

Asked by Gilberto Tetlalmatzi on 2021-01-20

Dear MadGraph developers

I want to produce the processes

p p > b b~ w+ w-,(w+ > l+ vl), (w- > j j)

and

p p > b b~ w+ w-,(w+ > j j), (w- > l- vl~)

in one single sample file. The difference is just the charge conjugation of the W products, notice that one of them is decaying leptonicaly while the other is decaying into jets. One possibility would be to do

p p > b b~ w+ w-,(w+ > l+ vl), (w- > j j), (w+ > j j), (w- > l- vl~)

my fear is that this will include all the permutations of the final states, i.e. cases where both w's decay into jets.

Please let me know how to address this task.

Thanks in advance!
Gilberto

I guess this is as simple as this:

generate p p > b b~ w+ w-,(w+ > l+ vl), (w- > j j)
add process p p > b b~ w+ w-,(w+ > j j), (w- > l- vl~)
output
launch

Cheers,

Olivier

Hi Oliver

Thanks a lot for your answer!

I did not know you could produce two processes in the same run. Apologies for the trivial question and thanks again for your answer.

Cheers

Gilberto
