This isn't a "science reporting" site: arXiv.org is providing the actual scientific article. The paper is supposed to require a specialized degree to understand: that's the intended audience of the vast majority of content on arXiv.org. (And for regular users of the site, it's immediately clear that no paper categorized as "hep-th: High Energy Physics - Theory" would be announcing actual observational results.) Aside: The authors of this article seem to have submitted a revised version a couple of weeks ago; sometimes (but not always) that coincides with either journal submission or responding to reviewer comments. There's no indication here yet of what its current stage in the peer review process is. Edit: I see from later comments here that the target of this link may have been changed to arXiv.org after its original submission. If the earlier link was paywalled as someone said, that suggests that this result has been formally published somewhere. (I'm a little surprised that the authors didn't note that on the arXiv page once it happened.) So maybe the earlier context made the purely theoretical nature of the paper less clear.
