Trying to visualize the behavior of high energy particles (physical particles like atomic nuclei, not Blender particles), I encountered the problem, that the decay of particles seems not be possible to simulate in Blender.

The particles I want to illustrate should behave the as follows:

Particle A moves with constant speed v, and either decays into two new particles, B and C, inheriting the same properties as A, or stops to exist. With the decay the particles gain a small amount of transversal momentum with respect to the initial movement of their mother-particle A.

The two actions (decaying or annihilating itself) shall occur randomly, however with the global probability p_decay and p_stop. p_decay is time dependent and should decrease from 1 to 0, p_stop can be given by p_stop = 1 - p_decay.

This should lead to the following picture: A single particle, after a certain time of flight, decays into two new particles, which decay further into two new ones and so on and so on. At some point a huge number of particles is created, but the probability for them to decay further has decreased sufficiently so that most of them stop to exist after a certain distance. In the end all particles seize to exist, since the probability p_stop became 1 and the probability p_decay became 0.

Is there any way to emulate this kind of behavior, or create objects randomly and dynamically at all?

Thanks in advance.
