You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

These particles are invariant under transformation of center vortices. Collisions of these particles result in excess strangeness at energies above 160 mega-electronvolts. These particles form a hypothetical composite whose ground state has a total angular momentum of three. Two of these particles fuse into a top loop in the dominant production mechanism of the Higgs boson observed at the LHC. Experiments at PETRA determined the spin of these particles via measurement of the Ellis-Karliner angle during three-jet events. These particles belong to the adjoint representation of SU(3) ["S-U-3"]. These particles generate a tensor field whose components are linear combinations of Gell-Mann matrices. Vacuum polarization of the virtual counterparts of these particles creates an anti-screening effect that gives rise to asymptotic freedom. These particles are responsible for the color confinement of quarks. For 10 points, name this group of eight gauge bosons that act as carriers of the strong force.
