A photon collider to access the 10 TeV parton-center-of-momentum (pCM) energy frontier of particle physics may enable the study of physics phenomena beyond the Standard Model. This collider, based on compact linear wakefield accelerator technology, could be realized through Compton scattering of multi-TeV lepton beams and moderate intensity laser pulses close to the collider interaction...

The 10 TeV Wakefield Collider Design Study, established in response to the 2023 P5 Report, has made significant progress since the study was announced at AAC 2024. Formed by a global community of particle theorists, HEP experimentalists, and accelerator scientists across national laboratories and universities, the Design Study has assembled dedicated working groups spanning LWFA, SWFA, and...

62. Laser-Based Collimation of Beam Halo Electrons via Compton Scattering

The design of future circular colliders will push beam currents and luminosities to unprecedented levels. Beam halo surrounding the main beam can deposit enough energy to melt conventional metal collimators and damage downstream components within a short time. Such damage was already observed during SuperKEKB commissioning [1]. A possible solution is to use Compton scattering to deflect halo...

64. Synergies for Near-Term Colliders and Advanced Accelerator R&D

We highlight a number of activities that leverage the expertise and facilities of the Advanced Accelerator community for near-term collider R&D, with a specific emphasis on the FCC-ee. These activities include 1) pulse-to-pulse charge tuning for an RF gun, 2) emittance preservation in an injector linac, 3) laser-based collimation and control of high-energy beams, and 4) the application of...

183. Coherent Phase Biasing of the Muon–Neutrino Transfer Channel as a Possible Path Toward Effective Muon Lifetime Enhancement

To be considered for Working Group talk

The finite lifetime of the muon remains one of the central challenges for energy-frontier muon colliders, motivating continued work in rapid acceleration, cooling, beam polarization, and mitigation of decay-induced detector backgrounds. We explore a complementary and highly speculative possibility: whether weak decay may be perturbed through coherent phase biasing of internal muon–neutrino...

72. Towards self-consistent simulations of colliders with BLAST

Future collider performance will be increasingly shaped by the complex dynamics at the interaction point (IP). Indeed, proposed and existing machines operate in regimes of unprecedented luminosity and beam-beam parameters. This demands high-fidelity and flexible modeling tools.

A key challenge is the development of simulation frameworks that remain reliable across diverse interaction...
