abstract = {A test of CP invariance in Higgs boson production via vector-boson fusion is performed in the H →
ττ decay channel. This test uses the Optimal Observable method and is carried out using 36.1 fb−1 of
√s = 13 TeV proton–proton collision data collected by the ATLAS experiment at the LHC. Contributions
from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described by
an effective field theory, in which the parameter ˜
d governs the strength of CP violation. No sign of CP
violation is observed in the distributions of the Optimal Observable, and ˜
d is constrained to the interval
[−0.090, 0.035] at the 68% confidence level (CL), compared to an expected interval of ˜
d ∈ [−0.035, 0.033]
based upon the Standard Model prediction. No constraints can be set on ˜
d at 95% CL, while an expected
95% CL interval of ˜
d ∈ [−0.21, 0.15] for the Standard Model hypothesis was expected.},
