Top Quark Interactions Under the Microscope
![The search for [latex] \text{CP} [/latex] violation in [latex] t\bar{t}Z [/latex] and [latex] Zq\bar{q} [/latex] production reveals sensitivity to both linear and quadratic effective field theory contributions, demonstrated by likelihood scans across the [latex] (c^{I}_{tW}, c^{I}_{tZ}) [/latex] plane, and highlighting a landscape where deviations from the Standard Model - marked by a specific cross - are actively sought within a complex parameter space.](https://arxiv.org/html/2601.05282v1/figures/fig1_cpv_contours.png)
