The hottest research claims to detect dark matter

Research claims that the detection of dark matter particles is questioned

there are rumors that CDMS particle detectors have found dark matter

recently, there has been a saying in the blogosphere that a team of physicists may have finally detected dark matter particles, a mysterious substance that aggregates galaxies through its own gravity. If this rumor is true, it is definitely one of the most important discoveries in history. What if the tensile testing machine fails to prompt online? But don't rush to book a ticket to Stockholm yet. Experts pointed out that considering the negative experimental results previously released by the same research group and the limited growth of their data scale since then, it can be said that the findings that have been widely implemented are still within the minimum of statistical significance

this rumor is mainly related to "low temperature dark matter detection" (CDMS), a small particle detector array hidden in the Soudan mine in Minnesota, USA. These detectors are composed of semiconductor germanium and silicon chips, which are designed to detect the so-called large mass weakly interacting particles, namely wimp, which constitute dark matter. According to some blogs involved in physics research, the CDMS research team will announce to the outside world on December 18 that they have detected such a particle impact, and the social awareness needs to be improved to hit the center of the chip, thus forming a distinctive electrical and thermal signal. In order to detect these signals, physicists must eliminate the external "background" interference from ordinary particles, such as neutrons that sometimes hit the detector

however, Richard gaitskell, a physicist at Brown University in the United States, said that in January this year, the CDMS research team published the analysis data of the array from October 2006 to July 2007, in which no evidence of wimp was found. He estimated that since then, CDMS has collected a large amount of data, which is enough to double its sensitivity. Even so, researchers may not find a powerful signal that cannot be generated from those background disturbances. Gaitskell said, "it would be lucky to find such particles. However, the increase in sensitivity is not enough to witness the emergence of 'oh my God!' at that moment." He said that after obtaining enough data to increase its sensitivity by 10 times, researchers may be able to find indisputable dark matter signals

nevertheless, researchers believe that finding dark matter in this way is still of great significance - gaitskell himself is also engaged in such an experiment, and because the problems can be eliminated in real time, many people hope that this effort will pay off in a few years. Whatever the outcome, the rumors surrounding the CDMS signal may imply the emergence of more decisive observations. However, it is not enough to convince physicists that dark matter has been discovered
