Hello all,
I'm a bit baffled by the fact that the various quite different components of the SM Lagrangian (or other systems, btw) are simply summed up, without even one ponderation coefficient, in the total Lagrangian. I know one reason it is like that is that... it works in practice, but I keep thinking there must be a more profound and/or mathematical reason for this (a rapid Google search on this didn't provide anything really conclusive).
Thanks for your help.
Bye,
Pierre
