Good explanation from you two, but let me ask: how much does the article states that this is a new "fundamental force" as opposed to simply some new particle working within the known forces?
From what I understood the angle would imply that this force interacts with a given range but not outside of this range (so it might be strong nuclear? hidden dimensions? new forces?)
In quantum field theories the forces are the same as new bosons. (The exact relationship is a bit hard to explain, since particles enter the picture as a really cool trick to solve PDEs, not as a fundamental entity of the theory.)
