The Cosine-100 Collaborative Research Unit of IBS (Institute for Basic Science) which SKKU research team led by Prof. Karsten Rott (Dept. of Physics) participated paved the way for long-standing controversy surrounding dark matter signal that Dama experiment had observed.
The results of this research were published at the online edition of Nature (IF 42.351) on December 6th at 3 AM. In the paper, data from the cosine-100 experiment suggested that there is insufficient evidence that the signal detected by the Dama experiment is caused by dark materials, and disproved most of the theories based on the results of the Dama experience.
Currently, two graduate students of our university are participating in the cosine-100 experiment and are conducting a detector simulation. SKKU team has been participated in this experiment from the beginning of detector production and is contributing on the data monitoring from the detector.
"The cosine-100 experiment will continue to collect data. We hope that we will be able to fully understand the anomalies observed by the Dama experiment, Prof. Karsten said. “Although this result does not directly identify the presence of dark matter, it may discovered a new phenomenon that we do not yet.”
