# Charge Conjugated process

Asked by Gilberto Tetlalmatzi on 2021-01-20

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.

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

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
