WG3 Accelerator Physics
The beta-beam concept relies on the production, by beta decay of radioactive ions of a very high flux, of an electron neutrino and anti-neutrino beam towards a distant detector. After production and acceleration in an accelerator complex consisting of a rapid cycling synchrotron, the CERN PS and the CERN SPS, the radioactive isotopes are injected into a long racetrack-shaped ring, called the decay

The Non Scaling FFAG is the main candidate for the final stage of muon acceleration in the Neutrino Factory according to the IDS-NF baseline. The alternative design for the muon acceleration based on two Non-Scaling FFAGs is studied. The staging of the Non-Scaling FFAGs requires lattices with careful chromaticity correction in order to suppress the longitudinal blow up of the beam simultaneously k

Twenty GeV Neutrino crossing along the Earth by longest base line (CERN-Deep Core or FNL-Deep Core) offer the most powerful tool to test neutrino (muon-tau) mixing masses and angles. An Opera-like experiment at 1% size and flux may lead to a few hundreds events a year of tau appearance or and muon suppression or disappearence. The large (11000 km) distance neutrino flux dilution is widely overcome

I argue that LHC may shed light on the nature of neutrino mass through the probe of the seesaw mechanism. The smoking gun signature is lepton number violation through the production of same sign lepton pairs, a collider analogy of the neutrinoless double beta decay. I discuss this in the context of L-R symmetric theories, which predicted
neutrino mass long before experiment and led to the seesaw

The MuSIC (Muon Science Innovative Channel) beam line at RCNP (Research Centre for Nuclear Physics, Osaka) will be the most intense source of muons in the world. A proton beam is incident on a target and, by using a novel capture solenoid, guides the produced pions into the beam line where they subsequently decay to muons. This increased muon flux will allow more precise measurements of cLFV (char

We consider a model where sterile neutrinos can propagate in a large compactified extra dimension giving rise to Kaluza-Klein (KK) modes and the Standard Model left-handed neutrinos are confined to a 4-dimensional spacetime brane.

We study the phenomenological consequences of the type I see-saw model, when the right-handed neutrinos have masses at the electroweak scale. Concretely, we discuss the prospects to produce and detect the right-handed neutrinos at colliders in view of the present constraints from electroweak precision observables and rare muon decays. We find that the most promising experiments to observe the firs
