Helicity based event generation

Asked by ouseph cj on 2021-03-18

Dear Madgraph expert,

Is it possible to generate events by specifying the helicity of the incoming and outgoing particle,
For example,
is it possible to generate the following event using madgraph,

generate uL vl > uL vl

uL=u quark left-handed
