Perhaps "scalar particle" ... but that is not a very suggestive title. One must specify that it is a boson. And then "scalar" is an adjective for that boson, as in "not a > 0 spin boson". So scalar boson is not redundant, as the "scalar fermion" remark suggests.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-26209572297940262182013-03-08T11:17:29.750+01:002013-03-08T11:17:29.750+01:00It was deliberate non-senseIt was deliberate non-senseAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-49651160806736866832013-03-08T02:00:44.083+01:002013-03-08T02:00:44.083+01:00Anonymous 7 March,
