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 B meson …

We enumerate the conditions necessary for CP violation to be manifest in nn¯ oscillations
and build a simple model that can give rise to such effects. We discuss a possible …

We propose a model for CP-violating oscillations of neutral, heavy-flavor baryons into
antibaryons at rates which are within a few orders of magnitude of their lifetimes. The flavor …

Future neutron-antineutron (nn¯) oscillation experiments, such as at the European
Spallation Source and the Deep Underground Neutrino Experiment, aim to find first …

Neutrino masses and quantum gravity are strong reasons to extend the standard model of
particle physics. A large extra dimension can be motivated by quantum gravity and can …

The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of
the Universe. This observation is a clear sign of new physics beyond the Standard Model …

We show how CP violating B meson oscillations in conjunction with baryon number violating
decays can generate the cosmological asymmetry between matter and antimatter, and …

We study general freeze-out scenarios where an arbitrary number of initial and final dark
matter particles participate in the number-changing freeze-out interaction. We consider a …

A bstract In the near future, the Deep Underground Neutrino Experiment and the European
Spallation Source aim to reach unprecedented sensitivity in the search for neutron …

The baryon asymmetry of the Universe is one of the central motivations to expect physics
beyond the Standard Model. In this Snowmass white paper, we review the challenges and …
