"Are these really "new" particles"
Maybe you need to define "new" first, when asking your question. A bit like "new" species of plants or animals being "discovered". The people who live in that area don't see them as "new". After all, they took time to evolve and the locals probably have them pan fried for supper every other week. But they could be "new" to science, in that they've not previously been recorded in "The Big Science Book of Everything" yet.
