Muon detection in electron-positron annihilation for muon collider studies

Abstract

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 environment with respect to hadronic colliders. One key element in the muon collider design is muon production with small emittance. Recently, the Low EMittance Muon Accelerator (LEMMA) collaboration has explored the close-to-threshold muon production by 45 GeV positron annihilating in a low Z material target. Muons are emerging with a natural small emittance. In this

Crystal-based pair production for a lepton collider positron source

“…For all these future accelerators, however, luminosity is the key factor to reach the desired precision. For lepton colliders e + e − and μ + μ − with muons produced by positrons [3][4][5][6] -the availability of intense and small emittance electron and positron beams is a crucial element to reach the required luminosity. In particular, a positron source represents a major challenge [7].…”
