When a matter and its corresponding anti matter collide, their annihilation leads to the formation of a new particle. But what really causes the collision of these particles from the conservation of energy point of view?

I don't really follow what you are asking. What is true is that we have conservation of energy.

Conservation of energy doesn't cause the collision.

The position of particles with respect to each other determines the forces between them, which may cause them to collide.

What's true is that, of course, energy is conserved in the collision.

Classically you don't need a force to cause a collision, it's just the trajectories of particles. For the particles in question, wave functions will overlap, and there is the possibility of an interaction.

good.

 

But how can we explain the overlapping of a wave function in a predictable way?

It depends on the situation. For e-e+ systems, once the particles have low KE, they form a bound state, and the interaction is inevitable. For high energy systems, you would look at the cross section and flux of the particles, and approach it statistically.
