You discovered the top quark!
At 174.2 GeV/c2, the top quark is the heaviest particle we know of. It belongs to the third generation of quarks and has a charge of ⅔. As a result of its large mass, it decays (mostly into bottom quarks) almost instantly after it is produced. This behemoth does not form bound states with other quarks or antiquarks.
