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 $γe^- \to \bar t bν_e$ ($γ$ is the Compton backscattering photon) and $e^+e^- \to e^-γ^* e^+ \to \bar t bν_e e^+$ ($γ^*$ is the Weizsacker-Williams photon) which are one of the most important sources of single top quark production. For the systematic uncertainties of $δ_{sys}=0\%,\hspace{1mm}5\%$, $b-\mbox{tagging efficiency}=0.8$, center-of-mass energy of $\sqrt{s}=3\hspace{0.8mm}TeV$, integrated luminosity of ${\cal L}=2\hspace{0.5mm}ab^{-1}$ and $2σ\hspace{1mm}(3σ)$ C.L. the future $e^+e^-$ collider may put bounds on the electromagnetic dipole moments $\hat a_V$ and $\hat a_A$ of the top quark of the order of ${\cal O}(10^{-2}-10^{-1})$, which are highly competitive with those recently reported in previous studies.
