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 …

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 standard model of particle physics is remarkably successful because it is consistent with
(almost) all experimental results. However, it fails to explain dark matter, dark energy and the …

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 …

A bstract The Fermilab Muon g− 2 experiment recently reported its first measurement of the
anomalous magnetic moment\({a} _ {\mu}^{\mathrm {FNAL}}\), which is in full agreement with …

A bstract Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-
energy extensions of the Standard Model (SM). We investigate the phenomenology of an …

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 …

New Particles Beyond the Standard Model have always been thought to be charged under
at least some of the same gauge interactions of ordinary particles. Although this assumption …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …
