You ca..."constraint is not all we want."<br /><br />You can't always get what you want. There is only so much that existing experiments can measure.andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-89518323119492615762015-04-26T23:20:10.412-06:002015-04-26T23:20:10.412-06:00Andrew: "A new study restricts the properties...Andrew: "A new study restricts the properties that the dark photon can have in a self-interacting dark matter model. ... Jester notes significant restrictions on dark photon parameter space from a variety of recent experiments. ... Thus, this data, collectively, and together with other data attempting to detect dark matter directly, further buttresses the idea that if dark matter exists, that it has almost no interactions with ordinary matter except via gravity. ... but these studies do strictly narrow the classes of self-interacting dark matter models that can be consistent with empirical evidence."<br /><br />Excellent post, much more clear than the Jester's. Yet, the constraint is not all we want.<br /><br />Matt Strassler had a few great post on Dark matter, and there was a very nice debate between Alain and emptyspacewaves. The debate starts at http://profmattstrassler.com/2015/04/20/completed-final-section-of-article-on-dark-matter-and-lhc/#comment-322571 .<br /><br />The most interesting and significant point is that Matt Strassler (a great Theoretical Physicist, the blog owner) keeps silent in those exchanges while he is always eagerly refuting other comments in his blog.Tienzenhttps://www.blogger.com/profile/05842156512465678309noreply@blogger.com
