Electron and virtual electron-positron pair

Click For Summary
SUMMARY

The discussion centers on the interaction between an electron and a virtual electron-positron pair, concluding that the probability of annihilation is effectively non-existent. When an electron interacts with a virtual positron, the energy is transferred to the remaining electron of the pair, rendering it non-virtual. This process is indistinguishable from an electron moving through space without any virtual pair involvement, leading to the assertion that there is no meaningful probability associated with this interaction.

What is the probability that an electron will be annihilated by a virtual electron-positron pair?

None. The electron could annihilate the positron of a virtual electron-positron pair, but that would just transfer the energy to the leftover electron of the pair, which wouldn't be virtual any more. But this process is indistinguishable from an electron just going from place to place with no virtual pair at all. So there is no meaningful probability for it.
