Originally hypothesized by Maxim Polyakov, Dmitri Diakonov, and Victor Petrov in 1997, it was believed purely speculational, although permitted by QCD, until compelling evidence was found in 2003 by Takashi Nakano and Ken Hicks.

The particle, given the symbol + (theta-plus), has a mass of approximately 1540  million electron volts, and while its baryon number is 1, like an ordinary baryon, it does not have the same flavor properties since the antiquark has a different flavor from all of the quarks. For ten points, what is this new type of particle, consisting of four quarks and an antiquark, five in all?
