Abstract The Gamma Factory (GF) is an ambitious proposal, currently explored within the
CERN Physics Beyond Colliders program, for a source of photons with energies up to≈ 400 …

The current status of the physics of massive neutrinos is reviewed with a forward-looking
emphasis. The article begins with the general phenomenology of neutrino oscillations in …

The use of accelerated beams of electrons, protons or ions has furthered the development of
nearly every scientific discipline. However, high-energy muon beams of equivalent quality …

A bstract We discuss sensitivities to lepton flavor violating (and conserving) interactions at
future muon colliders, especially at μ+ μ+ colliders. Compared with the searches for rare …

The conclusions of the Physics Working Group of the International Scoping Study of a future
Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried out by …

We study the prospects of probing neutrino mass models at the newly proposed antimuon
collider μ TRISTAN, involving μ+ e-scattering at s= 346 GeV and μ+ μ+ scattering at s= 2 …

We perform a global analysis of neutrino oscillation data in the framework of three neutrinos,
including the recent improved measurement of the neutral current events at the Sudbury …

A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the
energy frontier. Offering a combination of unprecedented energy collisions in a …

Abstract The international Muon Ionization Cooling Experiment (MICE), which is under
construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of …

Seesaw-type and low-scale models of neutrino masses are reviewed, along with the
corresponding structure of the lepton mixing matrix. The status of neutrino oscillation …
