How the Pacific got its bend
Nov. 9, 2017 10:31 AM
Hawaii sits at the end of a chain of volcanoes running across the Pacific Ocean floor, but in the middle of this chain lies a bend of 60 degrees. For many decades geoscientists have struggled to explain exactly how and why this feature occurred around 50 Million years ago. A new study from CEED, sheds light on this long-standing geological controversy – A massive collision at the edge of the Pacific Ocean was the culprit.

Dark matter freeze-out beyond the WIMP paradigm

Jan Heisig, RWTH Aachen
The origin and nature of the dark matter in the Universe is one of the most pressing questions in fundamental physics. The combination of particle physics and cosmology has proven to be a successful avenue leading to the well-established theory of big bang nucleosynthesis that explains the primordial abundances of light elements. In the similar manner an extrapolation to even earlier times in the Universe has led to the WIMP (Weakly Interacting Massive Particle) freeze-out paradigm - one of the best motivated explanations of the dark matter relic abundance measured today. However, despite an enormous experimental effort no conclusive hint for WIMPs has been found, putting pressure on the WIMP dark matter explanation. In this talk we examine new avenues beyond the standard WIMP picture. We show that scrutinizing the well-known co-annihilation scenario and dropping the commonly made assumption of chemical equilibrium between co-annihilating partners offers new phenomenological possibilities. By solving the full coupled set of Boltzmann equations we find solutions that accommodate the measured dark matter density while requiring very small couplings that are in accordance with current null-results in WIMP searches.
