摘要
Agglomeration of particles by perfectly inelastic collisions is studied in the case of a one-dimensional gas. Particles move freely between collisions. Both mass and momentum are conserved at binary encounters. It is shown that under a weak mean-field like hypothesis, admitting the existence of correlations between the velocities of colliding particles, the dynamics drives the system towards a scaling regime with a universal exponential distribution of masses.
