1. Probing top-quark couplings indirectly at Higgs factoriesCZ is supported by IHEP (Y7515540U1); EV is supported by a Marie Skłodowska-Curie Individual Fellowship of the European Commission’s Horizon 2020 Programme (704187) / Durieux, Gauthier ; Gu, Jiayin ; Vryonidou, Eleni ; Zhang, Cen
We perform a global effective-field-theory analysis to assess the combined precision of Higgs couplings, triple gauge-boson couplings, and top-quark couplings, at future circular e+e− colliders, with a focus on runs below the production threshold. [...]

5. Erratum to: Gluon-fusion Higgs production in the Standard Model Effective Field Theory / Deutschmann, Nicolas ; Duhr, Claude ; Maltoni, Fabio ; Vryonidou, Eleni
We have found that the definition of the operator O 1 $$ {\mathcal{O}}_1 $$ given in equation (2.2) and the one actually used to derive our results, including the renormalisation matrix, the anomalous dimension matrix and the RGE solutions presented in the paper, differ by an overall minus sign..
