== !MadGraph5 Syntax For generate events ==

Compared to [http://madgraph.phys.ucl.ac.be/EXAMPLES/example.html MG4 the syntax] is basically the same
but 
   1. All particles should be separated with a spaces
{{{
write this:
   w+ > ve e+
and not:
   w+>vee+
}}}
   2. The coupling is specify after the process in the same line. 
      Please note that:
        a. Note that contrary to !MG4 the default for the coupling is to infinity
        b. couplings are case sensitive
{{{
write this:
   w+ > ve e+ QED=2
and not:
   w+>ve e+ qed=2
}}}
   3. you can still use the special tag at the end of the process
      a. "/" fordids the following particles to appear in the process
      b. "$"  fordids the following particles to appear in a S-Channel

   4. The syntax for decay chain is different.
      a. In !MG5 the production process is separated from the decay by a coma. 
      b. Each part can be restricted by couplings/ special tag restrictions
{{{
write this:
   g g > t t~ QED=0 /a, (t > b W+, W+ > l+ vl), t~ >j j j QCD=0
and not:
   g g > (t >b (W+ >l+vl))(t~> j j j)      
}}}
   Note that If you run MG5 on MG4 proc_card. for a decay chains, then the couplings restriction will be applied only on the core process.
