One in ten million neutrons could disappear into another universe and matter swapping between universes could be initiated with a laser induced system. Technology Review – Their conclusion is that the probability of a neutron jumping ship is smaller than about one in a million. According to their theoretical work, a change in the gravitational potential should also influence the rate of matter swapping. So one idea is to carry out a neutron trapping experiment that lasts for a year or more, allowing the Earth to complete at least one orbit of the Sun. In that time, the gravitational potential changes in a way that should influence the rate of matter swapping. Indeed, there ought to be an annual cycle. “If one can detect such a modulation it would be a strong indication that matter swapping really occurs,” they say.
Recent theoretical works have shown that matter swapping between two parallel braneworlds could occur under the influence of magnetic vector potentials. In our visible world, galactic magnetism possibly produces a huge magnetic potential. As a consequence, this paper discusses the possibility to observe neutron disappearance into another braneworld in certain circumstances. The setup under consideration involves stored ultracold neutrons – in a vessel – which should exhibit a non zero probability p to disappear into an invisible brane at each wall collision. An upper limit of p is assessed based on available experimental results. This value is then used to constrain the parameters of the theoretical model. Possible improvements of the experiments are discussed.
Using results from performed experiments, we have assessed an upper limit on the probability for a stored ultracold neutron to disappear into another braneworld. This limit has been used to constrain the parameters of the brane model introduced in recent theoretical works, which had shown the possibility of matter exchange between two braneworlds invisible to each other. We have discussed the sensibility of further experiments to probe the existence of a neighbouring brane through an annual study. It is also suggested that a laser-induced matter swapping towards a hidden braneworld could be tested in the next decades
