This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average …

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 …

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 …

With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Abstract The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose
underground liquid scintillator detector, was proposed with the determination of the neutrino …

Abstract The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting
the full scientific potential of the CERN's accelerator complex and scientific infrastructures …

Assuming a horizontal symmetry SUF (n), we demonstrate a possibility that the left-handed
neutrinos receive masses of order 1eV, which is consistent with recent experiments on …
