AFAIK the effects due to the Higgs are not normally considered a separate force; to the extent they are a "force" at all, they are considered part of the electroweak interaction (the Higgs mechanism for giving mass to other particles, for example, is an effect of electroweak symmetry breaking).
- 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.
