In a typical collider experiment, two particles, generally in(adsbygoogle = window.adsbygoogle || []).push({}); approximate momentum eigenstates at ##t=-\infty##, are collided with each other and we measure the probability of finding particularoutgoing.

momentum eigenstates at ##t=\infty##

Firstly, what does it mean for the particles to be inapproximatemomentum eigenstates? Does it mean that there is a small spread in the distribution of the momentum of the particles, due to the particles being in a superposition of momentum eigenstates, so that the particles are rather inapproximatemomentum eigenstates, so to speak?

Secondly, how can we be certain that the experiment produces only momentum eigenstates at ##t=\infty## and not some superposition of momentum eigenstatesat ##t=\infty##?
