Design of a Collimation Section for the FCC-ee

Tatiana Pieloni

The design parameters of the FCC-ee foresee operation with a total stored beam energy of about 20 MJ, exceeding those of previous lepton colliders by almost two orders of magnitude. Given the inherent damage potential, a halo collimation system is studied ...

Muon Collider. A Path to the Future?

Andrea Wulzer

A muon collider would be both a precision and a powerful discovery machine, because it can offer collisions of point-like particles at very high energies, strongly exceeding the energy reach of other lepton colliders. It can even match the discovery of a p ...

Probing new physics with displaced vertices: Muon tracker at CMS

Lesya Shchutska, Alexey Boyarsky, Oleg Ruchayskiy, Kyrylo Bondarenko

Long-lived particles can manifest themselves at the LHC via "displaced vertices"-several charged tracks originating from a position separated from the proton interaction point by a macroscopic distance. Here we demonstrate the potential of the muon tracker ...

The active muon shield in the SHiP experiment

Lesya Shchutska, Aurelio Bay, Ekaterina Kuznetsova, Sun Hee Kim, Elena Graverini, Federico Leo Redi, Mikhail Chapochnikov, Alexey Boyarsky, Oleg Ruchayskiy, Inar Timiryasov, Sebastian Gerlach

The SHiP experiment is designed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. An essential task for the experiment is to keep the Standard Model background leve ...

Composite charge 8/3 resonances at the LHC

Francesco Riva

In composite Higgs models with partial compositeness, the small value of the observed Higgs mass implies the existence of light fermionic resonances, the top partners, whose quantum numbers are determined by the symmetry (and symmetry breaking) structure o ...

The nu MSM and muon to electron conversion experiments

Mikhail Chapochnikov, Laurent Canetti

We review briefly the different constraints on the three right-handed neutrinos of the nu MSM, an extension of the Standard Model that can explain baryon asymmetry, dark matter and neutrino masses. We include in the discussion the proposed experiments on m ...

An improved method for measuring muon energy using the truncated mean of dE/dx

Matthias Wolf, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

The measurement of muon energy is critical for many analyses in large Cherenkov detectors, particularly those that involve separating extraterrestrial neutrinos from the atmospheric neutrino background. Muon energy has traditionally been determined by meas ...
