2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/83596New self-consistent parameter sets are presented and discussed for muon collider rings at center-of-mass energies of 10, 30 and 100 TeV. All three parameter sets attain luminosities of 3 x 10^35 /cm^2/s. The parameter sets benefit from new insights gained at the HEMC'99 workshop that considered the feasibility of many-TeV muon colliders.3 pages, no figures. Submitted to Proc.
