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

SUMMARY:Seminario: Cosmological Constant and Renormalization Group Running in the IR
DESCRIPTION:Lecturer: Ilya Shapiro (Universidade Federal de Juiz de Fora\, Brazil on sabbatical leave at DFTUZ/UNIZAR). \nAbstract: The Cosmological Constant (CC) Problem emerges in Quantum Field Theory (QFT) in curved space-time owing to the enormous magnitude of the induced vacuum energy. The CC Problem looks rather complicated\, such that its solution from the first principles is not a realistic perspective\, even in a far future. After reviewing the fundamental CC problem\, we consider the possibility of a slightly variable CC because of the quantum effects of matter fields. There is no way to calculate relevant quantum contributions directly in the framework of available QFT methods. However\, three different approaches converge to the unique form of the possible running of CC and the effective Newton constant G in the lowenergy limit. Assuming covariance\, or the standard quadratic decoupling of massive fields at low energies\, or using dimensional arguments\, we arrive at the unique possible form of a running\, which leads to the relatively simple cosmological model with potentially observable predictions. Much more recent result is that this possible running\, with a single phenomenological parameter\, may be useful in alleviating various tensions existing nowadays in cosmology.
