Produce vector boson strictly on-shell

Hi Harikrishnan,

I would propose to use Madspin for the decay where you can switch off the BW effect (require MG5 v2.0.0 or newer).
So you generate
p p > w+ w-
then ask Madspin for the decay
and edit the madspin_card to have only the requested electron decay
and in that file you set the following options:
set BW_effect False

Another option, is to do the same with the DECAY package but this is less precise.

Cheers,

Olivier

Is there anyway i could do this inside madgraph? setting bw=0 gives me zero cross section because madgraph merely trims the tail and 0 phase space is left.

Hi Olivier,
Thank you for your proposal. However, it still produces Ws off-shell.
Copied the lhe file including first event for your perusal.
Thank you.
