Axions exposed

A Clarification to this article was published on 09 February 2017

This article has been updated

Physicists are hunting for a particle called the axion that could solve two major puzzles in fundamental physics. An ambitious study calculates the expected mass of this particle, which might reshape the experimental searches. See Letter p.69 See Clarification p.176
