LHC Probes of TeV-Scale Scalars in Grand Unification

Figure 1

Running of the gauge couplings for the model. The vertical dotted lines from left to right correspond to the symmetry breaking scales , , and , which also indicate the beginning of the energy intervals I, II, and III, respectively. For and , we plot the redefined quantities and . Note that the discontinuity on the plot at the energy scale occurs due to the boundary condition given in (6).
