N05.00002: Towards the Muon Collider Detectors Invited Speaker: Sergo Jindariani A Muon Collider with the centre-of-mass energy of 3 to 10 TeV has gained a lot of interest in the recent years thanks to its unique combination of high energy reach, clean final states and low environmental footprint. However, as muons are unstable particles such a machine will be accompanied with technological challenges for a collider experiment: an unprecedented amount of secondary and tertiary decay products will enter the detector volume. The detector design, choice of technology, and reconstruction algorithms are therefore heavily influenced by the 'beam-induced background'. In this talk we describe the challenge, present the initial detector concept and full simulation studies of data reconstruction performance, and demonstrate that high quality physics is possible in the muon collider environment. |

N05.00003: Positron-Driven Sources of Low Emittance Muons for Future Colliders Invited Speaker: Emilio A Nanni Muon colliders are an intriguing option for future lepton colliders with the ability to reach high energy with high luminosity, conceivably even into the >10 TeV scale. Muons benefit from the increased particle mass with respect to electrons allowing for acceleration with recirculating beams. However, Muon colliders face significant challenges with the production of high flux low emittance beams and managing the short lifetime of muons. The leading approach for generating muon and anti-muon pairs relies on a high intensity proton beam to produce vast quantities of relatively low energy muons which are then captured, accelerated and “cooled” to lower the muon beam emittance. An alternative approache is using high energy positron beams on fixed targets to produce high energy muons with lower emittance. A positron beam of >45 GeV is required for efficient muon pair production on a fixed target. The muons that are produced have an energy of >20 GeV and a lifetime of >450 microseconds in the laboratory frame increasing the possibility for beam capture and beam collection. We will present a review of the proposed concepts for positron-driven low emittance muon sources for future colliders, possible schemes for implementation and needed areas for research and development. |

N05.00004: Accelerator Physics Challenges for an Energy Frontier Muon Collider Invited Speaker: Mark A Palmer Muon colliders offer a unique path to multi-TeV, high-luminosity lepton collisions. Muon collisions with a center-of-mass energy of 10 TeV or above would offer significant discovery potential where the constituent collision energies exceed those of the LHC program by an order of magnitude. Significant progress on the fundamental R&D and design concepts for such a machine has led to a new international effort to assemble a conceptual design within the next few years. This effort will assess the viability of such a machine as a successor to the LHC program. The remaining challenges and the R&D required to deliver a complete machine description will be described. |
