Figure 3

Relative rate ${ϵ}_{gg}$ in Eq. (32), showing the effect of the inclusion of a real color octet scalar (top row) or complex color triplet scalar (bottom row), for $m_h=125\mathrm{GeV}$ (left panels) or $m_h=500\mathrm{GeV}$ (right panels). At the center of each plot, from top to bottom, the solid lines correspond to ${\lambda }_{hp}=-0.2$, $-0.05$, 0.05, 0.2. The left (right) gray bands in the octet scalar plots come from the ATLAS (CMS) search for pair produced dijet resonances. For the triplet case, the CMS bound still applies but the ATLAS bound is unconstraining after rescaling cross sections.Reuse & Permissions

Contours of the relative rate of $s_1$ production as a function of $m_{t_2}$ and the left-handed mixing angle in the top partner scenario for $m_{s_1}=800\mathrm{GeV}$, $v_{\varphi }=500\mathrm{GeV}$, and ${\lambda }_{hp}=-1$ (left) and 0.75 (right). We adapt the analysis and results of Ref. 19 to show shaded contours which are consistent with the oblique parameters $S$ and $T$ at the 68 and 95% C. L.Reuse & Permissions

Figure 6

Relative rate of $s_1$ production with Higgs mixing and a new color octet fermion (left) and a new color triplet fermion (right). We choose $v_{\varphi }=500$, $m_{s_1}=500$, and $m_{s_2}=700\mathrm{GeV}$. From top to bottom, the solid lines in each plot correspond to ${\lambda }_{hp}=0.015$, 0.005, $-0.005$, $-0.015$.Reuse & Permissions

Figure 8

Loop functions $F_L=F_F$ (top), $F_L=F_S$ (middle), and $F_L=F_V$ (bottom) for fermion, scalar, and vector particles of mass $M$, respectively. The loop functions develop an imaginary part for $\tau >1$, which corresponds to the particles in the loop going on-shell.Reuse & Permissions

Figure 9

Relative rate of $s_1$ production showing the effect of adding only the coloron (top row) and the effect of adding the coloron and $G_H$, with $m_{G_H}=140\mathrm{GeV}$ (bottom row). From top to bottom, the solid lines correspond to ${\lambda }_{hp}=-0.0015$, $-0.001$, 0.001, 0.0015. In the left panels, the gray bands correspond to the pair-produced dijet bounds from ATLAS (left) and CMS (right). In the right panels, the left gray band corresponds to the CMS exclusion on coloron production in dijet resonance searches. The left vertical dotted line corresponds to the minimum $m_{G^{\prime }}$ mass allowed given the specified choice of $v_{\varphi }$, and the right vertical dotted line corresponds to the perturbativity constraint.Reuse & Permissions
