Measurements of tV and ttV production with ATLAS and CMS detectors.

The study of ttV and tV processes provides direct information off the electroweak couplings of the top to weak bosons. Deviations from the Standard Model predictions might indicate the presence of Beyond Standard Model physics in the EWK or top-quark sectors, either in the form of anomalous couplings, CP violating couplings or sizeable $t$/$\bar{t}$ spin asymmetry and/or $t\bar{t}$ spin correlations. In this talk, the latest precision measurements in ATLAS and CMS at $\sqrt{s}$ = 13 TeV of the associated production of Z, W or $\gamma$ bosons with $t\bar{t}$ or single-$t$ are presented.
