Their siblings – up and down quarks – are what make up protons and neutrons. But top quarks don't stick around long enough to make much of anything most of us would recognise, decaying in a split second.
They are remarkably heavy, though. An electron has roughly one three-millionth the mass of a top quark, indicating a relatively strong interaction with the Higgs field.
Catching this interaction requires having hints of a Higgs boson appearing together with a top quark in something called a ttH production. This is easier said than done. Neither particle exists long enough to be seen directly, and only 1 percent of Higgs bosons produced by the energies of the LHC appear alongside a top quark.
