abstract = {$\mathcal{CP}$ violation in the Higgs couplings to fermions
is an intriguing, but not yet extensively explored
possibility. We use inclusive and differential LHC Higgs
boson measurements to fit the $\mathcal{CP}$ structure of
the Higgs Yukawa couplings. Starting with simple effective
models featuring $\mathcal{CP}$ violation in a single
Higgs-fermion coupling, we probe well-motivated models with
up to nine free parameters. We also investigate the
complementarity of LHC constraints with the electron
electric dipole moment bound, taking into account the
possibility of a modified electron Yukawa coupling, and
assess to which extent $\mathcal{CP}$ violation in the
Higgs-fermion couplings can contribute to the observed
baryon asymmetry of the Universe.Even after including the
recent analysis of angular correlations in
$H\to\tau^+\tau^-$ decays, we find that a complex tau Yukawa
coupling alone may be able to account for the observed
baryon asymmetry, but with large uncertainties in the
baryogenesis calculation.A combination of complex top and
bottom quark Yukawa couplings yields a result four times
larger than the sum of their separate contributions, but
remains insufficient to account for the observed baryon
asymmetry.},
