That can be renormalized.
Because of this, renormalizable theories are insensitive to the precise nature of the underlying high-energy short-distance phenomena. Source: Internet
A theory is perturbatively renormalizable when the constants in the Lagrangian only diverge at worst as logarithms of the lattice spacing for very short spacings. Source: Internet
In general, a QFT is called renormalizable, if all infinities can be absorbed into a redefinition of a finite number of coupling constants and masses. Source: Internet
The renormalization group describes how renormalizable theories emerge as the long distance low-energy effective field theory for any given high-energy theory. Source: Internet
From a technical point of view, the problem is that the theory one gets in this way is not renormalizable and therefore cannot be used to make meaningful physical predictions. Source: Internet
In this case the theory is said to be renormalizable. Source: Internet
