Bounds on the electromagnetic dipole moments through the single top production at the CLIC

We obtain bounds on the anomalous magnetic and electric dipole moments of the t-quark from a future high-energy and high-luminosity linear electron positron collider, such as the CLIC, with unpolarized and polarized electron beams which are a powerful tool to determine new physics. We consider the processes γet¯bνe (γ is the Compton backscattering photon) and e+eeγe+t¯bνee+ (γ is the Weizsacker-Williams photon) which are one of the most important sources of single top quark production. For a center-of-mass energy of s=3TeV, integrated luminosity of =2ab1 and 2σ(3σ)C.L. the future e+e collider may put bounds on the electromagnetic dipole moments a^V and a^A of the top quark of the order of 102, which are highly competitive or even better that those recently reported in previous studies.
