univeral theory Posted February 10, 2013 Share Posted February 10, 2013 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? Link to comment Share on other sites More sharing options...

ldarko29 Posted February 10, 2013 Share Posted February 10, 2013 But what really causes the collision of these particles from the conservation of energy point of view? 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. Link to comment Share on other sites More sharing options...
swansont Posted February 10, 2013 Share Posted February 10, 2013 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. 1 Link to comment Share on other sites More sharing options...

swansont Posted February 12, 2013 Share Posted February 12, 2013 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. Link to comment Share on other sites More sharing options...
