abstract = {${\mathcal {C}}{\mathcal {P}}$ 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
${\mathcal {C}}{\mathcal {P}}$ structure of the Higgs Yukawa
couplings. Starting with simple effective models featuring
${\mathcal {C}}{\mathcal {P}}$ 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 ${\mathcal {C}}{\mathcal {P}}$
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
$H\rightarrow \tau ^+\tau ^-$ 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.},
