Such a model describes a system of hard spheres such that, whenever two particles meet, they either annihilate with probability $\\alpha \\in (0,1)$ or they undergo an elastic collision with probability $1-\\alpha$. The existence of a self-similar profile for $\\alpha$ smaller than an explicit threshold value $\\underline{\\alpha}_1$ has been obtained in our previous contribution (J.
