Quartification denotes an extension of trinification models, which postulate a left-right-symmetry due to the gauge group SU(3)c × SU(3)L × SU(3)R. Quartification promotes this gauge group with the inclusion of a leptonic color interaction SU(3)l, thus creating a SU(3)4 for the total gauge group of the theory. In this theory leptons and quarks are now completely symmetric. Breaking of the quartification gauge group down to the standard model reveals new doublets with half-integer electric charge, so-called hemions. The hemions are confined by the SU(2)l remnant interaction and thus can only exist in the form of integer charged boundstates.
We study the creation and decay of hemion boundstates via proton collisions at the LHC, both for quark antiquark annihilations via a γ/Z0 channel and a W± channel.
