 abstract = {Particles of low velocity, traveling without dissipation in a
superfluid, can interact and emit sound when they collide. We propose a
minimal model in which the equations of motion of the particles,
including a short-range repulsive force, are self-consistently coupled
with the Gross-Pitaevskii equation. We show that this model generates
naturally an effective superfluid-mediated attractive interaction
between the particles; and we study numerically the collisional dynamics
of particles as a function of their incident kinetic energy and the
length scale of the repulsive force. We find a transition from almost
elastic to completely inelastic (sticking) collisions as the parameters
are tuned. We find that aggregation and clustering result from this
sticking transition in multiparticle systems.},
