We discuss the existence of the smooth density of the law of a certain sde driven by Lévy noise process. Our discussion is based on the Malliavin calculus on Wiener-Poisson space, see the paper Y. Ishikawa, H. Kunita, Malliavin calculus on the Wiener-Poisson space and its application to canonical sde with jumps, SPA, 116 (2006), 1743-1769.
