Dark matter does not contain certain axion-like particles
Stockholm, Sweden (SPX) Apr 25, 2016
Researchers at Stockholm University are getting closer to corner light dark-matter particle models. Observations can rule out some axion-like particles in the quest for the content of dark matter. The article is now published in the Physical Review Letters. Physicists are still struggling with the conundrum of identifying more than 80 percent of the matter in the Universe. One possibility is that it is made up by extremely light particles which weigh less than a billionth of the mass of the electr ... read more
