Scientists working on the DZero particle detector experiment have for the first time successfully observed pairs of Z bosons at the Tevatron. Pair production of these force carrying particles is extremely rare and difficult to detect, and researchers say that having observed them represents a big step towards observing the Higgs boson itself.
