Probing braneworld hypothesis with a neutron-shining-through-a-wall experiment

Abstract : The possibility for our visible world to be a 3-brane embedded in a multidimensional bulk is at the heart of many theoretical edifices in high energy physics. Probing the braneworld hypothesis is then a major experimental challenge. Following recent theoretical works showing that matter swapping can occur between braneworlds, we propose a "neutron-shining-through-a-wall" experiment. We first show that an intense neutron source such as a nuclear reactor core can induce a hidden neutron flux in an adjacent hidden braneworld. We then describe how a low background detector can detect neutrons arising from the hidden world and we quantify the expected sensitivity to the swapping probability. As a proof of concept, a constraint is derived from previous experiments.
