“…Bottom quark tagging is done using CLIC's tight working point [45], which consists of a flat 50% b-tagging efficiency with energy and η-dependent mistagging rates ranging from 0.07%-3% for c-quarks and 0.02%-0.6% for light quarks, respectively. This corresponds well to the existing conservative full-simulation b b studies [15,33], which can serve as a potential floor for b-tagging. Since the Delphes card does not include c-tagging by default, we use flat rates inspired by ILC [46,47].…”

“…All studies in this section are performed using the MC and fast simulation as outlined in Section 2. However, in the case of b b production at 3 TeV, there is a corresponding full simulation study including BIB [33] that we show the comparison to in Section 3.1.1.…”

“…Moreover, there can be more modern techniques used in conjunction such as precision timing detectors like at the HL-LHC [31,32] that should be able to further mitigate the effects of the BIB beyond what has been studied thus far. A summary of the current status of muon detector design and full simulation can be found in [33,34]. We do not include any effects BIB in our simulation assuming they can be sufficiently mitigated.…”

“…However, for a muon collider to even simulate the BIB requires an understanding of the accelerator design and the machine detector interface (MDI) which is much more correlated than for e + e − or pp colliders. Currently, the state of the art simulation from the IMCC includes BIB simulated at E CM = 1.5 TeV; however, physics studies with full simulation at 3 TeV are then overlaid with the 1.5 TeV BIB [33]. Given that the BIB contribution should become more forward at higher CM energy, this allows for a conservative estimate of the effects of BIB at 3 TeV.…”

Muon colliders are an exciting possibility for reaching the highest energies possible on the shortest timescale. They potentially combine the greatest strengths of e + e − and pp colliders by bridging the energy versus precision dichotomy. In this paper we study the sensitivity of Higgs properties that can be achieved with a future 3 or 10 TeV muon collider from single Higgs production. The results presented here represent the first comprehensive picture for the precision achievable including backgrounds and using fast detector simulation with Delphes. Additionally, we compare the results of fast detector simulation with available full simulation studies that include the muon collider specific Beam Induced Background, and show the results are largely unchanged. We comment on some of the strengths and weaknesses of a high energy muon collider for Higgs physics alone, and demonstrate the complementarity of such a collider with the LHC and e + e − Higgs factories. Furthermore, we discuss some of the exciting avenues for improving future results from both theoretical and detector R&D that could be undertaken.

“…The decays of the muons also lead to a large "beam-induced background" (BIB), which must be effectively mitigated by a combination of shielding and precision timing in the detectors [74]. Recent advances have begun demonstrating that these challenges can be overcome [75][76][77][78], however, coinciding with a surge of interest in the physics potential of a high-energy muon collider facility [4,5,[79][80][81].…”

Complementary Signals of Lepton Flavor Violation at a High-Energy Muon Collider

A muon collider would be a powerful probe of flavor violation in new physics. There is a strong complementary case for collider measurements and precision low-energy probes of lepton flavor violation (as well as CP violation). We illustrate this by studying the collider reach in a supersymmetric scenario with flavor-violating slepton mixing. We find that the collider could discover sleptons and measure the slepton and neutralino masses with high precision, enabling event reconstruction that could cleanly separate flavor-violating new physics signals from Standard Model backgrounds. The discovery reach of a high-energy muon collider would cover a comparably large, and overlapping, range of parameter space to future µ → e conversion and electron EDM experiments, and unlike precision experiments could immediately shed light on the nature of new physics responsible for flavor violation. This complementarity strengthens the case that a muon collider could be an ideal energy-frontier laboratory in the search for physics beyond the Standard Model.
