Idea

For $C$ a monoidal model category and $T : C \to C$ a monad on $C$, there is under mild conditions a natural model category structure on the category of algebras over a monad over $T$.

Definition

Let $C$ be a cofibrantly generated model category and $T : C \to C$ a monad on $C$.

Then under mild conditions there exists the transferred model structure on the category of algebras over a monad, transferred along the free functor/forgetful functor adjunction

$(F \dashv U) : Alg T \stackrel{\overset{F}{\leftarrow}}{\underset{U}{\to}} C \,.$

See (SchwedeShipley, lemma 2.3).
