Semantics is generally not the most interesting topic, but since the actual science behind the title claim is well-discussed elsewhere...
We already have strong evidence of a fifth force, the Higgs force, by most accountings (assuming you enumerate the other low-energy forces as gravity, electromagnetism, and the strong and weak forces; or, if you look at the higher-energy gravity, SU(3), SU(2), and U(1); either way).
IF the g-2 experiments point to unknown particles (which seems unlikely), that could (and also could not) point to a sixth force.

- addaon 3y agoAs I said, semantics. But Higgs bosons do mediate momentum transfer, which is about as good a definition of a force as I can come up with. See e.g. http://resonaances.blogspot.com/2016/01/higgs-force-awakens.html http://resonaances.blogspot.com/2016/01/higgs-force-awakens....
- pdonis 3y ago> Higgs bosons do mediate momentum transfer The blog post you reference appears to say that this is true in theory (though impossible to detect experimentally as the effect is so tiny), but it would be nice to see an actual paper describing the specifics. For example, what do the Feynman diagrams for this "Higgs force" interaction look like?
- addaon 3y agoSee e.g. https://arxiv.org/abs/1601.05087 https://arxiv.org/abs/1601.05087; the area around eq 3 discusses the attractive force due to Higgs boson exchange, and the paper as a whole discusses testability.
