# A Case of Quantum Scattering

## TL;DR

This paper investigates quantum scattering by analyzing an experiment with crossing laser beams and a wire, demonstrating that complementarity is upheld when scattering interactions consistent with conservation laws are considered.

## Contribution

It reveals that scattering interactions, essential for complementarity, are implicit in quantum formalism and active only under conservation law conditions.

## Key findings

- Complementarity inequality is fulfilled with scattering interactions.
- Scattering interactions are implicit in quantum theory formalism.
- Interactions are active only when conservation laws are satisfied.

## Abstract

We analyze the results of an experimental setup that consist of two statistically independent laser beams that cross, interfere and end at detectors. At the beam intersection we place a thin wire at the center of a dark interference fringe and analyze the complementarity inequality. We find that the complementarity inequality is fulfilled provided we include a scattering interaction. We find that this interaction is implicit in the formalism of quantum theory; however, this interaction is active only when the conservation laws are satisfied.
