Abstract The Large Hadron Collider (LHC) has confirmed the Higgs mechanism to generate
mass in the Standard Model (SM), making it attractive also to consider spontaneous …

A bstract We present a comprehensive analysis of electroweak, flavor, and collider bounds
on the complete set of dimension-six SMEFT operators in the U (2) 5-symmetric limit. This …

We posit that the distinct patterns observed in fermion masses and mixings are due to a
minimally broken U (2) q+ e flavor symmetry acting on left-handed quarks and right-handed …

A timely and long-term programme of kaon decay measurements at an unprecedented level
of precision is presented, leveraging the capabilities of the CERN Super Proton Synchrotron …

A bstract The future muon collider has the potential to discover feebly interacting particles in
a wide range of masses above the electroweak scale. It is particularly suitable to search for …

Axion-like particles (ALPs) that decay into photon pairs pose a challenge for experiments
that rely on the construction of a decay vertex in order to search for long-lived particles. This …

We review the experimental status of searches for lepton-flavour violation in the charged
sector. We give an overview of searches for lepton-flavour violation in purely leptonic …

The excellent experimental prospects to measure the invisible mass spectrum of the K+→
π+ ν ν¯ decay opens a new path to test generalised quark–neutrino interactions with flavour …

The Experimental Cavern North 3 (ECN3) is an underground experimental cavern on the
CERN Pr\'evessin site. ECN3 currently hosts the NA62 experiment, with a physics …
