Higgs portal dark matter models assume a coupling between dark matter and baryonic matter through Higgs exchange. These models are constrained in the low mass sector through limits on the branching ratio into invisible Higgs decays. Higgs portal models are also increasingly tested in the high-mass sector through direct search experiments. I review the current status of the Higgs portal models...
In this talk I will discuss a recently proposed model of "Dark Baryon Superfluid" dark matter. This scenario begins with a unified model of dark-genesis and baryogenesis, involving strongly interacting dark quarks, and utilizing the gravitational anomaly of chiral gauge theories. In these models, both the visible and dark baryon asymmetries are generated by the gravitational anomaly induced by...
We use QCD Laplace sum-rule to explore meson-hybrid mixing in vector heavy quarkonium. Our cross-correlator calculation supplements perturbation theory with non-perturbative corrections proportional to the four-dimensional and six-dimensional gluon condensates and the six-dimensional quark condensate. After forming the Laplace sum-rule we use experimentally determined hadronic masses to build...
