The weak force is also short range but we have neutrinos as test particles - we can shoot neutrinos at a target and see that once in a while they get deflected. In your example of NR scattering on nucleons, whatever test particle we use the Higgs force will always be negligible compared to the EM, weak or strong forces involved. But if we had e.g. a dark matter particle that interacts only via the Higgs forces, that would be a different story :-) Jesterhttps://www.blogger.com/profile/08947218566941608850noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-8009069131161455632013-01-02T23:51:59.498+01:002013-01-02T23:51:59.498+01:00"It's a legitimate attractive force.

Summing coherently for heavy nuclei over the nucleons, and you will end up with a sizable attractive force. The problem is instead the short range.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-88879279661938194242013-01-02T17:44:55.248+01:002013-01-02T17:44:55.248+01:00Hmmm, since bosons and fermions are already taken ...Hmmm, since bosons and fermions are already taken that only leaves anyons to the Asians.

Also, it doesn't have to be a part of the Higgs sector, it doesn't even have to be a scalar. If the particle has charge but no color it won't affect other decays than to gamma-gamma (except maybe Z-gamma). In specific models, like type-II 2HDM there would indeed be strong constraints on the charged Higgs from Bs to mu-mu, and b to s gamma, but that's model dependent. Certainly, a 100+ GeV charged particle cannot be excluded in a model independent way.

"...Jester, on the digamma excess rate you say:<br /><br />"If this were true, the most likely explanation would be a new charged particle with the mass of order 100 GeV and a large coupling to the Higgs"<br /><br />Are you talking here about a doubly charged Higgs or something else? A doubly charged Higgs would have left its signature in the Bs to dimuon channel, which we know it is ruled out by the latest reports. In any event, shouldn’t a new charged particle with mass around 100 GeV and strongly coupled to the Higgs affect other decay channels?Ervin Goldfainhttps://www.blogger.com/profile/07585008304556273617noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-81320891220186192392013-01-01T11:56:38.593+01:002013-01-01T11:56:38.593+01:00It's a legitimate attractive force.
