The solution to the Hardy's paradox

General Physics 2025-08-12 v3

Abstract

By using both, the weak-value formulation as well as the standard probabilistic approach, we analyze the Hardy's experiment introducing a complex and dimensionless parameter (ϵ\epsilon) which eliminates the assumption of complete annihilation when both, the electron and the positron departing from a common origin, cross the intersection point PP. We then find that the paradox does not exist for all the possible values taken by the parameter. The apparent paradox only appears when ϵ=1\epsilon=1; however, even in this case we can interpret this result as a natural consequence of the fact that the particles can cross the point PP, but at different times due to a natural consequence of the energy-time uncertainty principle.

Significant improvements. One figure and two tables added in order to clarify the paradox. The most fundamental expressions unchanged and fully verified
