A study of muon-electron elastic scattering in a test beam

G. Abbiendi, G. Ballerini, D. Banerjee, J. Bernhard et autres

Abstract In 2018, a test run with muons in the North Area at CERN was performed, running parasitically downstream of the COMPASS spectrometer. The aim of the test was to investigate the elastic interactions of muons on atomic electrons, in an experimental …

Muon detection in electron-positron annihilation for muon collider studies

M. Antonelli, G. Ballerini, C. Biino, A. Cappati et autres

The investigation of the energy frontier in physics requires novel concept for future colliders. The idea of a muon collider is very appealing since it would aim to study particle collisions up to tens of TeV energy while offering a cleaner experimental …

The ENUBET experiment

F. Terranova, F. Acerbi, G. Ballerini, M. Bonesini et autres

The CERN NP06/ENUBET experiment is designing the first ``monitored neutrino beam'', i.e. a neutrino beam with unprecedented control of the flux, energy, and flavor of the neutrinos at the source. The original aim of ENUBET was to monitor the $\nu_e$ production mostly …

The ENUBET narrow band neutrino beam

ENUBET Collaboration, M. Tenti, Fabio Acerbi, G. Ballerini et autres

The narrow band beam of ENUBET is the first implementation of the "monitored neutrino beam" technique proposed in 2015. ENUBET has been designed to monitor lepton production in the decay tunnel of neutrino beams and to provide a 1% measurement of the …

KLEVER: An experiment to measure BR($K_L\toπ^0ν\barν$) at the CERN SPS

F. Ambrosino, R. Ammendola, A. Antonelli, K. Ayers et autres

Precise measurements of the branching ratios for the flavor-changing neutral current decays $K\toπν\barν$ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, $K^+\toπ^+ν\barν$ and $K_L\toπ^0ν\barν$, since different new physics models …
