SUMMARY:Seminario Temas Actuales: Any Light Particle Search
DESCRIPTION:Lecturer: Dr. Axel Lindner\, Spokesperson of the ALPS II collaboration at DESY in Hamburg\, Germany \nAbstract: ALPS II at DESY in Hamburg searches for axions — hypothetical particles that could help explain\ndark matter and other mysteries of modern physics. The experiment uses the “light-shining-through-awall” technique: laser light is sent toward a light-tight barrier\, while strong magnetic fields may allow a\ntiny fraction of photons to convert into axions\, pass through the wall\, and reappear as light on the other\nside.\nIn its first science run\, ALPS II excluded photon–axion conversion probabilities down to the 1e-13 level\,\nimproving the sensitivity to the axion–photon coupling strength by about a factor of 20 over previous\nexperiments of this kind. The ongoing upgrade is expected to make ALPS II the first purely laboratorybased experiment to probe beyond existing astrophysical limits on axions.\nAfter the search for new particles\, the ALPS II infrastructure will also be used to study the quantum\nvacuum through magnetic birefringence and\, ultimately\, to search for high-frequency gravitational waves
