One might conclude that the global hunt for dark matter is entering desperate days, at least when it comes to the mystery material's most-often theorized form—the weakly interacting massive particle (WIMP). Results out today from the Stanford University-led LUX experiment, among the premiere dark matter detection projects, once again offer no detections, while, at the same time, offering better data representing finer sensitivities on particle-mass ranges where slight dark matter hints had been previously registered. Those ranges can now be safely ruled out.
The new LUX results are set to be published in the Physical Review Letters, while an open-access preprint version of the report was posted to the arXiv server last week.
