Composite Higgs Models with a Hidden Sector
Ann Nelson, Michael Park, Devin Walker
We discuss the phenomenology of composite Higgs models that naturally produce a Standard Model-like Higgs boson with a mass of GeV. The effective theory below the compositene…
Baryogenesis and Dark Matter from Mesons
Gilly Elor, Miguel Escudero, Ann E. Nelson
We present a new mechanism of Baryogenesis and dark matter production in which both the dark matter relic abundance and the baryon asymmetry arise from neutral meson oscillatio…
Reducing the Quadratic Divergence in the Higgs Mass Squared Without Top Partners
Sonia El Hedri, Ann E. Nelson, Devin G. E. Walker
We examine a model with multiple scalar fields to see whether it is possible to reduce the fine- tuning of the SM Higgs mass without introducing low scale top partners. Our approac…
Dark halos around neutron stars and gravitational waves
Ann Nelson, Sanjay Reddy, Dake Zhou
We find that a class of models of MeV-GeV dark matter in which dark matter interacts strongly can be constrained by the observation of gravitational waves from neutron star mergers…
Neutron stars exclude light dark baryons
David McKeen, Ann E. Nelson, Sanjay Reddy +1
Exotic new particles carrying baryon number and with mass of order the nucleon mass have been proposed for various reasons including baryogenesis, dark matter, mirror worlds, and t…
