- W3209750220 abstract "A new proposal to compute the anomalous chromomagnetic dipole moment of the top quark, $hat{mu}_t$, in the Standard Model is presented. On the basis of the effective coupling $gg bar{t}t$, the anomaly is extracted trough both four-body triangle and box diagrams at the one-loop level. We calculate $hat{mu}_t(s)$ for both spacelike and timelike domains as a function of the energy scale $s=mp E^2$, in the interval $E=[10,1000]$ GeV. By considering the running of the quark masses and alpha strong through the $overline{textrm{MS}}$ scheme, in particular, at the $Z$ boson mass scale, we found that the spacelike $hat{mu}_t(-m_Z^2)$ $=$ $-0.025$$+$$0.00384i$ and the timelike $hat{mu}_t(m_Z^2)$ $=$ $-0.0318$$-$$0.0106i$. Since the experimental measurements consider the influence of the $gbar{t}t$ and $ggbar{t}t$ couplings at the same time, we resort to the average of $hat{mu}_t$ by taking into account the three- and four-body vertices at the one-loop level, specifically, $hat{mu}_t^textrm{Avg}(-m_Z^2)=$ $-0.0237+0.00146i$ and $hat{mu}_t^textrm{Avg}(m_Z^2)=$ $-0.0225-0.0186i$. In contrast, the experimental central value is $hat{mu}_t^textrm{Exp}=-0.024$, then by comparing it with $|hat{mu}_t^textrm{Avg}(-m_Z^2)|=$ $0.0237$ and $|hat{mu}_t^textrm{Avg}(m_Z^2)|=$ $0.0292$, it can be established that the spacelike prediction is the favored one." @default.
