“…Perhaps the most intriguing signatures here will be those from the production of solely A D and h 3 states, since these both have sub-GeV masses and will always be kinematically accessible at a multi-TeV muon collider. In the event that these particles decay invisibly, it should be possible to constrain the production rate for these particles via a simple monophoton search, such as what has been considered for a WIMP dark matter model in [68,69]. 5 As these cross sections scale quartically with y SL and y SE , such a measurement can be used to constrain or observe these couplings, which from Eqs.…”

The paradigm of portal matter represents a well-motivated extension to models with kinetic mixing/vector portal dark matter. In previous work, we constructed a simple leptonic portal matter model in which the portal matter fields could mediate a new physics correction to the anomalous magnetic moment of the muon consistent with the observed discrepancy between the measured value for this quantity and the SM prediction. Here, we present a version of this mechanism by constructing a model with an extended dark gauge sector in which SM and portal matter fields exist as members of the same dark gauge multiplets, which provides a natural extension of simple portal matter models. We find a rich phenomenology in this extended model, including nontrivial novel characteristics that do not appear in our earlier minimal construction, and discuss current experimental constraints and future prospects for this model. We find that a multi-TeV muon collider has excellent prospects for constraining or measuring the crucial parameters of this model.

New studies of the reach of a high energy Muon Collider [441,485,[496][497][498][499][500] were developed within Snowmass 2021 in addition to the studies within the Briefing Book for the European Strategy for Particle Physics Update [412].…”

“…jets) [437,501]. At lepton colliders, other signatures involving SM EW gauge bosons and leptons come into play [485,496,497,499,500]. These signals are relatively insensitive to the splitting between masses of the EW multiplet and, hence, more robust against variations beyond the minimal scenario.…”

The Energy Frontier (EF) aims at investigating the fundamental physics of the Universe at the highest energies or -equivalently -the shortest timescales after the Big Bang. We investigate open questions and explore the unknown using various probes to discover and characterize the nature of new physics, through the breadth and multitude of collider physics signatures. While the naturalness principle suggests new physics to lie at mass scales close to the electroweak scale, in many cases direct searches for specific models have placed strong bounds around 1-2 TeV. Thus, the energy frontier has moved beyond the TeV scale and the exploration of the 10 TeV scale becomes crucial to shed light on physics beyond the Standard Model (SM).We need to use both energy reach and precision measurements to push beyond the 1 TeV scale in our exploration. The quest for new physics will be thus conducted in a two-tier approach: 1) looking for indirect evidence of beyond-the-Standard-Model physics (BSM) through precision measurements of the properties of the Higgs boson and other SM particles, and 2) searching for direct evidence of BSM physics at the energy frontier, reaching multi-TeV scales.The EF currently has a top-notch program with the LHC and the High Luminosity LHC (HL-LHC) at CERN, which sets the basis for the EF vision. The EF supports continued strong US participation in the success of the LHC, and the HL-LHC construction, operations, computing and software, and most importantly in the physics research programs, including auxiliary experiments.The discussions on projects that extend the reach of the HL-LHC underlined that preparations for the next collider experiments have to start now to maintain and strengthen the vitality and motivation of the community. Colliders are the ultimate tool to carry out such a program thanks to the broad and complementary set of measurements and searches they enable. Several projects have been proposed such as ILC, CLIC, FCC-ee, CEPC, Cool Copper Collider (C 3 ) or HELEN for e + e − Higgs Factories, and CLIC at 3 TeV centre-of-mass energy, FCC-hh, SPPC and Muon Collider for multi-TeV colliders. For a detailed discussion of timeline, cost, challenges of those accelerator projects we refer to the Accelerator Frontier Integration Task-Force (ITF) report [1] and Appendix A.3. Dedicated fora were established across frontiers to bring together diverse expertise in the study of future e + e − and µ + µ − colliders. Results from their studies are available in their reports [2, 3] and have informed the studies presented in this report.All proposed collider physics experiments need complex detectors as well as software and computing infrastructure, with cutting-edge technologies to meet their ambitious physics goals. The needs extend beyond generic R&D. Experience from R&D and building previous experiments informs us that it takes about 10 years from CD-0 (Critical Decision -0) to the end of construction of a collider detector. For e + e − Higgs factories, immediate investment in targeted detector R&...
