Recently, a model consisting of triangular trimers covering the triangular lattice was introduced and its exact free energy given. In this paper we present the complete calculation leading to this exact result. The solution involves a coordinate Bethe ansatz with two kinds of particles. It is similar to that of the square-triangle random tiling model by Widom and Kalugin. The connection of the trimer model with related solvable models is discussed.

“…Rg . We note that the doublet-triplet splitting problem is solved by the orbifolding since the Z 2 parity of the colored Higgs field is (+, −) and it become massive [19]. Some comments on U(1) X gauge symmetry which remains unbroken by orbifolding are given.…”

Grand gauge-Higgs unification of five dimensional SU (6) gauge theory on an orbifold S 1 /Z 2 with localized gauge kinetic terms is discussed. The Standard model (SM) fermions on one of the boundaries and some massive bulk fermions coupling to the SM fermions on the boundary are introduced. The SM fermion masses including top quark are reproduced by mild tuning the bulk masses and parameters of the localized gauge kinetic terms. Gauge coupling universality is not guaranteed by the presence of the localized gauge kinetic terms and it severely constrains the Higgs vacuum expectation value. Higgs potential analysis shows that the electroweak symmetry breaking occurs by introducing additional bulk fermions in simplified representations. The localized gauge kinetic terms enhance the magnitude of the compactification scale, which helps Higgs boson mass large. Indeed the observed Higgs boson mass 125 GeV is obtained.

“…Gauge symmetry breaking via orbifolding [1,2,3] is a popular alternative to spontaneous breakdown of gauge symmetry in four dimensions. This has many reasons, including the observation that the infamous doublet-triplet splitting problem has a simple solution [4,5,6,7,8,9,10]. The low-energy continuous gauge symmetry in these models is well studied [2,9].…”
