We reexamine the simplified dark matter(DM) models with fermionic DM particle and spin-0 mediator.The DM-nucleon scattering cross sections in these models are l
Vacuum polarization is a part of the initial-state radiative correction for the cross-section of e^+e^- annihilation processes. In the energy region in the vici
A top quark mass measurement scheme near the tt production threshold in future e+e- colliders, e.g. theCircular Electron Positron Collider (CEPC), is simulated. A
