New Results from the XENON100 Experiment

In astrophysics, weakly interacting massive particles or WIMPs, are hypothetical particles serving as one possible solution to the dark matter problem. These particles interact through the weak force and gravity, and possibly through other interactions no stronger than the weak force. Because they do not interact with electromagnetism they cannot be seen directly, and because they do not interact with the strong nuclear force they do not react strongly with atomic nuclei.
In this seminar Dr. Aprile presents new results from the XENON experiment, designed to observe WIMPs-nucleon scattering in liquid xenon with unprecedented sensitivity.
