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 …

Specialized data-taking and data-processing techniques were introduced by the CMS
experiment in Run 1 of the CERN LHC to enhance the sensitivity of searches for new …

This paper reports world averages of measurements of b-hadron, c-hadron, and τ-lepton
properties obtained by the Heavy Flavor Averaging Group using results available before …

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 …

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 …

Abstract The Forward Physics Facility (FPF) is a proposal to create a cavern with the space
and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider …
