I understand that by uncertainty relations, it is possible use an EFT to a range of energy, forgotten the interactions for bigger energies. But, ¿ why change the values of coupling costants?
And, ¿ how can tell that there is no intermediate particle that happens with low probability in scatterings that don´t let found the effective lagrangian? ¿ How we can that no more particles in standard model?
