Consider a particle-antiparticle creation, lets say an electron and a positron. I am curious if there is any lasting connection* between particles and the antiparticles that they were born with (in terms of the physics of their interaction). Has anyone ever predicted or observed such a lasting connection? Has it already been ruled out by experiment? *In an E&M book I read, they mentioned the idea that charge particles were connected to their corresponding birth-antiparticles by a topological handle. Then electric field lines never end. (Imagine a smooth sphere with a handle, the points of contact between handle and sphere are what we call particles and antiparticles. Draw electric field lines on the handle as if those spots were the charges, and you will see what I am talking about).
