The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

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 present cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

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 …

The observation of electromagnetic radiation from radio to γ-ray wavelengths has provided a
wealth of information about the Universe. However, at PeV (10 15 eV) energies and above …

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

The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

The MiniBooNE experiment at Fermilab reports a total excess of 638.0±52.1 (stat.)±122.2
(syst.) electronlike events from a data sample corresponding to 18.75× 10 20 protons-on …

We present cosmological parameter results from the final full-mission Planck measurements
of the CMB anisotropies. We find good consistency with the standard spatially-flat 6 …
