Detector design and R&D directions for a future Multi-TeV Muon Collider

Abstract

A Multi-TeV muon collider is one of the best candidates for the future development of High Energy Particle physics in the post High Luminosity LHC era. Such a machine will allow to reach high center-of mass energy in leptonic collisions, thus opening the path to a vast and mostly unexplored physics program. However, the design of a suitable detection apparatus represents a technological challenge, mainly because of the unstable nature of the muons. The interaction of the muon decay products with the machine elements, can produce an intense flux of background particles that eventually reach the detector and may degrade its performance. In this contribution, the latest simulation studies performed to optimize the detector design will be presented, together with an overview of the detector technologies that have a potential to match the challenging specifications of a muon collider, with a focus on the ongoing R&D efforts.
