Of course, the discovery of molecular states, pentaquark hadrons, etcetera would be exciting; it is not clear, however, that these might be ascribed to Physics beyond the standard model, since quantum chromodynamics contains no definite rule against such states.

However, back in the 1960s, Gell-Mann also raised the possibility of more exotic combinations of quarks, such as tetraquarks (two quarks and two antiquarks) and pentaquarks (four quarks and one antiquark).
