  Numerous soft materials jam into an amorphous solid at high packing fraction.
This non-equilibrium phase transition is best understood in the context of a
model system in which particles repel elastically when they overlap. Recently,
however, it was shown that introducing any finite amount of attraction between
particles changes the universality class of the transition. The properties of
this new ``sticky jamming'' class remain almost entirely unexplored. We use
molecular dynamics simulations and scaling analysis to determine the shear
modulus, bulk modulus, and coordination of marginal solids close to the sticky
jamming point. In each case, the behavior of the system departs sharply and
qualitatively from the purely repulsive case.
