Abstract

Abstract: The expected measurement precisions of elastic scattering cross sections are estimated for μ + μ + and μ + e − colliders, which have recently been proposed as future realistic possibilities (μTRISTAN). Compared with contributions from possible new physics represented by higher-dimensional operators, we find that the measurements at a TeV energy μ + μ + collider can probe the scale of new physics up to O (100) TeV. A μ + e − collider for the Higgs boson factory can also improve the electroweak precision test. For those studies, we assume the expected integrated luminosity at μTRISTAN, L int = 120 fb −1 ( μ + μ + ) and 1 ab −1 ( μ + e − ).
