The identity of dark matter is a question of central importance in both astrophysics and
particle physics. In the past, the leading particle candidates were cold and collisionless, and …

Theoretical and phenomenological implications of R-parity violation in supersymmetric
theories are discussed in the context of particle physics and cosmology. Fundamental …

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

Cosmological gravitational particle production (CGPP) is the creation of particles in an
expanding universe due solely to their gravitational interaction. These particles can play an …

We review physics of light pseudoscalars (axions, majorons and familons) and their effects
in cosmology. The axions which solve the strong CP problem play important roles in …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

Leptogenesis is a class of scenarios where the baryon asymmetry of the Universe is
produced from a lepton asymmetry generated in the decays of heavy singlet neutrinos. We …

We review the collider phenomenology of neutrino physics and the synergetic aspects at
energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass …

Current upper bounds on the neutron electric dipole moment constrain the physically
observable quantum chromodynamic (QCD) vacuum angle| θ¯|≲ 10− 11. Since QCD …

In the see-saw model, the baryon asymmetry of the Universe can be generated by the decay
of the lightest right-handed neutrino, νR. For a hierarchical spectrum of right-handed …
