Lighting Through A Wall Experiment

We present here the 2sigma limits obtained so far with our novel setup consisting of a pulsed magnetic field and a pulsed laser.

Lighting through a wall experiment.

Recently axionlike particle search has received renewed interest. To leading order we find that when the photon frequency ωis very close to the axion mass m there is a threshold cusp. An example of this is the so called axion. Like the wimps the suspected particle does not belong to the standard model of particle physics nor is it clear that it actually exists.

Shining light through walls. The wavy line indicates the photon field and the dashed line the axion field. At first glance this sounds crazy. The alps collaboration runs a light shining through a wall lsw experiment to search for photon oscillations into weakly interacting sub ev particles wisps inside of a superconducting hera dipole magnet at the site of desy.

An x ray version of this experiment has recently been proposed by rabadán et al. Nevertheless there are quite a number of experimental collaborations around. Unfortunately with present and near future technologies the opportunity to observe light shining through walls via these effects is completely out of question. In modern physics the double slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles.

In this paper we have described and characterized our apparatus and demonstrated the data analysis procedures. Several different calculational methods are employed and compared and in all cases we retain a nonzero axion mass. The idea behind the double slit experiment is that even if the photons are sent through the slits one at a time there s still a wave present to produce the interference pattern. The analysis of light shining through a wall experiments.

However very feeble gravitational and electroweak effects allow for this exotic possibility. The experiment is to search for particles that can shine light through a wall. And two recent optical laser lsw experiments have reported preliminary results. Moreover it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
