A Supersymmetric Theory of Baryogenesis and Sterile Sneutrino Dark Matter from Mesons
Gonzalo Alonso-Álvarez, Gilly Elor, Ann E. Nelson +1
Low-scale baryogenesis and dark matter generation can occur via the production of neutral mesons at MeV temperatures in the early Universe, which undergo CP-violating oscillati…
Lattice-Friendly Gauge Completion of a Composite Higgs with Top Partners
Helene Gertov, Ann E. Nelson, Ashley Perko +1
We give an explicit example of a composite Higgs model with a pseudo-Nambu-Goldstone Higgs in which the top Yukawa coupling is generated via the partial compositeness mechanism. Th…
Baryogenesis from B Meson Oscillations
Ann E. Nelson, Huangyu Xiao
We show how CP violating B meson oscillations in conjunction with baryon number violating decays can generate the cosmological asymmetry between matter and anti-matter, and explore…
