Homological stability for Artin monoids

We prove that certain sequences of Artin monoids containing the braid monoid as a submonoid satisfy homological stability. When the $K(pi,1)$ conjecture holds for the associated family of Artin groups this establishes homological stability for these groups. In particular, this recovers and extends Arnolds proof of stability for the Artin groups of type $A$, $B$ and $D$.
