Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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 …

We study the direct detection prospects for a representative set of simplified models of sub-
GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmological …

The proposed LDMX experiment would provide roughly a meter-long region of instrumented
tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each …

A bstract Dark matter in the sub-GeV mass range is a theoretically motivated but largely
unexplored paradigm. Such light masses are out of reach for conventional nuclear recoil …

A bstract High-energy colliders offer a unique sensitivity to dark photons, the mediators of a
broken dark U (1) gauge theory that kinetically mixes with the Standard Model (SM) …

We review theories of Asymmetric Dark Matter (ADM), their cosmological implications and
detection. While there are many models of ADM in the literature, our review of existing …

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …
