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, Lint = 120 fb−1 (μ+μ+) and 1 ab−1 (μ+e−).
