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 …

This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Charged lepton flavour-violating transitions would be a clear signal of new physics beyond
the Standard Model. Their search has been carried out in a variety of channels, the most …

The Higgs-boson mass used to be the only unknown input parameter of the electroweak
contributions to (g-2) μ in the Standard Model. It enters at the two-loop level in diagrams …

A bstract We examine the low-energy signatures of axion-like particles (ALPs) in lep-ton
flavor violating (LFV) processes. By using a dimension-5 effective Lagrangian, we compute …

The first direct search for lepton-flavour-violating decays of the recently discovered Higgs
boson (H) is described. The search is performed in the H→ μ τ e and H→ μ τ h channels …

The second part of this review is devoted to the Higgs sector of the Minimal Supersymmetric
Standard Model. The properties of the neutral and charged Higgs bosons of the extended …

A bstract We study a class of nonstandard interactions of the newly discovered 125 GeV
Higgs-like resonance that are especially interesting probes of new physics: flavor violating …

The muon anomalous magnetic moment is one of the most precisely measured quantities in
particle physics. In a recent experiment at Brookhaven it has been measured with a …

A bstract A search for charged Higgs bosons decaying into W±W±or W±Z bosons is
performed, involving experimental signatures with two leptons of the same charge, or three …
