Description

The 4321 model is one of the best model providing an explanation for the B anomalies. Although all of the gauge couplings exhibit asymptotic freedom or run very slowly, we found that Landau poles can arise at one-loop at relatively low scale, from the quartic part of the extended scalar sector. We also discuss the possibility of radiative electroweak symmetry breaking and its incapacity in alleviating the little hierarchy problem brought by the presence of new TeV-scale scalar states.Finally, the idea of coupling/mass unification in the UV is explored, motivated by UV completions of the 4321 model such as PS^3.
