Class Decay_info

source code

all routine linked to the reconaissance of the topology from the proc card

The proc-card has two information:
    1) the process decay pp>(t>blvl~)(t~>(W->l~vl)b)
    2) the MultiParticle content

The diagram is treated as follow:
    1) We don't consider production part (i.e. how the first on-shell particle are produced)
    2) We will check mass shell possibility for all 1->2 decay
    3) We will not consider possibility of mass shell for 1->3,4,...
          even if they are only one possibility or one possibility is dominant

first_part_pid(self, text, pid)

source code 

find the pid(s) of the fist tag in text. return the text without this tag and the pid. pid is a dictonary
