## Main Question or Discussion Point

Given a theory with n-different fields [tex] \phi _{n}(x) [/tex] and a known Lagrangian L is possible to see at first sight if the theory will be renormalizable or non*-renormalizable ?? , or on the other hand should we calculate ALL the infinite diagramms to see it, for example i give a certain Lagrangian involving scalar particles, spin 1 particles and spin*-2 particles and several coupling constants could you say if this is renormalizable or not ?
