How do you observe a process that takes more than one trillion times longer than the age of the universe? The XENON Collaboration research team did it with an instrument built to find the most elusive particle in the universe – dark matter.
Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1X10-47 square centimeters—one-trillionth of one-trillionth of a centimeter squared—the most stringent limit yet determined for dark matter as established by the world’s most sensitive detector.
Results from its first run indicate that XENON1T is the most sensitive dark matter detector on Earth.
A team of international scientists involved in the XENON100 project have demonstrated the sensitivity of their detector and recorded results that challenge several dark matter models and a longstanding claim of dark matter detection.
