Richard Gaitskell, professor of physics, will present the first results from the LUX dark matter experiment at a physics department colloquium on Monday, Nov. 4, at 4 p.m. The results were first announced Wednesday, Oct. 30, at the site of the experiment in Lead, S.D. The initial 90-day run of LUX did not detect dark matter particles, but the device proved to be the most sensitive dark-matter detector in the world. The experiment was able to rule out potential detections by other experiments of “low-mass” dark-matter particles. The LUX team will now make minor adjustments to the detector in anticipation of a 300-day run to begin next year. Gaitskell is one of the experiment’s spokespeople and a founding researcher. The talk will be held in Barus and Holley, Room 168.
