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

We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

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 …

The LHCb Upgrade II will fully exploit the flavour-physics opportunities of the HL-LHC, and
study additional physics topics that take advantage of the forward acceptance of the LHCb …

Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

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

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 …

A plausible explanation for the lightness of neutrino masses is that neutrinos are massless at
tree level, with their mass (typically Majorana) being generated radiatively at one or more …

A bstract In recent years, experiments revealed intriguing hints for new physics (NP) in semi-
leptonic B decays. Both in charged current processes, involving b→ cτν transitions, and in …
