Abstract: We consider a new family of $\R^d$-valued L\-{e}vy processes that we callLamperti stable. One of the advantages of this class is that the law of manyrelated functionals can be computed explicitely see for instance \cite{cc},\cite{ckp}, \cite{kp} and \cite{pp}. This family of processes shares manyproperties with the tempered stable and the layered stable processes, definedin Rosi\-nski \cite{ro} and Houdr\-e and Kawai \cite{hok} respectively, forinstance their short and long time behaviour. Additionally, in the real valuedcase we find a series representation which is used for sample paths simulation.In this work we find general properties of this class and we also provide manyexamples, some of which appear in recent literature.
