Question

The value “violet” is added to this theory in the Pati–Salam model. This theory cannot include the decay products of any R-parity-conserving theory’s LSP, which is a WIMP in the “minimal supersymmetric” version of this (20[1])theory. (20[2])Unobserved (20[1])heavy neutrinos (20[1])are implied by extending this theory with the type (20[1])I (“one”) seesaw mechanism. (20[1])This theory’s gauge interactions (20[1])are explained by (*) grand (10[1])unified theories. (10[2])This theory’s failure (10[1])to explain gravitation (10[1])could be resolved (10[1])by the (10[1])discovery of the (10[1])graviton. (10[3])Columns represent three “generations” (10[2])of this theory in its representation as a four-by-four grid next to the Higgs boson. Three of the fundamental forces are explained by, for 10 points, what theory underlying particle physics? (10[1])■END■ (10[9])

ANSWER: Standard Model [prompt on grand unified theories or GUTs until “grand unified theories” is read by asking “on what theory is that theory based?”] (“LSP” stands for “lightest supersymmetric particle.”)
