I read in a newspaper that the Higgs boson might be the new boson but that this was not confirmed, because we don't know its properties, e.g. its spin or parity. Now I see it confirmed that it is the Higgs boson, but, really, is it true?
I don't have access to the journal Physical Review D, and I can't find a clear detailed explanation of the claim or the alternative possibilities. Could someone explain it for this curious layman?
