摘要

我们考虑了镜像孪生希格斯粒子(MTH)中的自然不对称暗物质(ADM)模型。我们证明，当双重子是DM时，可以获得正确的暗物质(DM)丰度，而不需要在无量纲耦合中显式破坏MTH - 2对称(即不需要硬破坏)。我们说明了这在一个特定的重子发生设置中是如何可能的，这也导致了adm。在最简单的情况下，我们得到m DM ~ O (1) GeV，刚好高于质子质量。我们给出了目前和未来实验中直接检出率的估计。

Baryogenesis and dark matter in the mirror twin Higgs

A bstract We consider a natural asymmetric dark matter (ADM) model in the mirror twin Higgs (MTH). We show that it is possible to obtain the correct dark matter (DM) abundance when a twin baryon is the DM without the need of explicit breaking of the MTH ℤ 2 symmetry in the dimensionless couplings (i.e. without hard ℤ 2 breaking). We illustrate how this is possible in a specific baryogenesis setup, which also leads to ADM. In the simplest scenario we obtain m DM ~ O (1) GeV, just above the proton mass. We show estimates for direct detection rates at present and future experiments.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
