High Energy Physics Seminar

Dark sectors with confining gauge interactions can provide both simple dark matter candidates and striking signals at colliders. I will present why a class of models featuring dark quarks with electroweak charge, in addition to dark color, may lead to baryonic dark matter candidates whose direct detection signals are surprisingly suppressed (so-called Noble Dark Matter). Colliders may therefore have the best prospects for discovery, and I will also describe how the dark mesons of the theory can lead to long-lived particle and resonant decay signatures. Existing searches at the LHC probe these states up to the TeV scale, and future searches will significantly expand this reach. These findings raise additional questions regarding other potential collider signals, cosmological abundances, and novel mechanisms to naturally keep dark sectors hidden while some discovery mechanism remains.

The talk is in 469 Lauritsen.
