| Abstract: |
We study top-quark pair production in electron–positron collisions within the framework of the minimal noncommutative Standard Model. Noncommutative effects are incorporated using the Seiberg–Witten map, and the scattering squared amplitude for the process e + e − → t t ̄ is computed consistently up to second order in the noncommutativity parameter Θ μ ν . We derive the total cross-section, the polar and azimuthal angular distributions, and the forward–backward asymmetry, all of which exhibit sensitivity to spacetime noncommutativity. Numerical results are evaluated for center-of-mass energies relevant to future linear colliders, such as the ILC and CLIC. Our analysis demonstrates that noncommutative geometry can induce significant characteristic deviations from the Standard Model predictions, offering a potential indirect probe of spacetime noncommutativity at high-energy e + e − collisions.
