Asymmetric Matters from a Dark First-Order Phase Transition
Eleanor Hall, Thomas Konstandin, Robert McGehee +1
We introduce a model for matters-genesis in which both the baryonic and dark matter asymmetries originate from a first-order phase transition in a dark sector with an $SU(3)\times…
Baryogenesis from a dark first-order phase transition
Eleanor Hall, Thomas Konstandin, Robert McGehee +2
We present a very minimal model for baryogenesis by a dark first-order phase transition. It employs a new dark gauge group with two doublet Higgs bosons, two lepton dou…
Absorption of Fermionic Dark Matter by Nuclear Targets
Jeff A. Dror, Gilly Elor, Robert McGehee
Absorption of fermionic dark matter leads to a range of distinct and novel signatures at dark matter direct detection and neutrino experiments. We study the possible signals from f…
Freeze-Twin Dark Matter
Seth Koren, Robert McGehee
The mirror twin Higgs (MTH) addresses the little hierarchy problem by relating every Standard Model (SM) particle to a twin copy, but is in tension with cosmological bounds on ligh…
Direct Detection Signals from Absorption of Fermionic Dark Matter
Jeff A. Dror, Gilly Elor, Robert McGehee
We present a new class of direct detection signals; absorption of fermionic dark matter. We enumerate the operators through dimension six which lead to fermionic absorption, study…
A Predictive Mirror Twin Higgs with Small Breaking
Keisuke Harigaya, Robert McGehee, Hitoshi Murayama +1
The twin Higgs mechanism is a solution to the little hierarchy problem in which the top partner is neutral under the Standard Model (SM) gauge group. The simplest mirror twin Higgs…
