Technicolor Dark Matter

Abstract

Dark Matter candidates are natural in Technicolor theories. We introduce a general framework allowing to predict signals of Technicolor Dark Matter at colliders and set constraints from earth based experiments such as CDMS and XENON. We show that the associate production of the composite Higgs can lead to relevant signals at the Large Hadron Collider.

Figures (5)

• Figure 1: TIMP -- nucleon cross section for $d_M=1$, $\Lambda=3$ TeV, $M_H=300$ GeV and $d_B=\pm 1$ as a function of the TIMP mass. The plus sign corresponds to the thin-solid-red line and the minus one to the thin-dotted-black line. Also plotted is the approximate exclusion limit from CDMS II Ge Combined (solid-thick-blue) and XENON10 2007 (dashed-thick-blue). The long-dashed-blue line is the projected superCDMS exclusion curve. The allowed region is below the CDMS and XENON curves.
• Figure 2: CDMS exclusion limit in the $d_B - d_M$ plane for a 100 GeV TIMP with $\Lambda=3$ TeV and $M_H=300$ GeV. The colored region is excluded.
• Figure 3: Feynman diagram for missing energy signal in a TC model with (axial-) vector resonances $R_{1,2}$ and a TIMP $\phi$.
• Figure 4: The invisible branching ratio of the Higgs into $\phi^\ast \phi$ for $d_M=1$ and $M_H=$160 (black), $M_H=$300 (red) and $M_H=450$ (green).
• Figure 5: $pp \to ZH$ with $Z\to e^+ e^-$ for three different values of the composite Higgs mass. On the x-axis we plot ${\slash\!\!\!\!\!\:p}_T$ assuming a completely invisible Higgs decay. Also shown (in the lower black curve) is the distribution arising from a SM Higgs with $M_H=160$. The cuts are those in Eq. \ref{['eq:cuts1']} and \ref{['eq:cuts2']}.
