Constraints on anomalous HVV couplings from the production of Higgs bosons decaying to tau lepton pairs
A study is presented of anomalous HVV interactions of the Higgs boson, including its CP properties. The study uses Higgs boson candidates produced mainly in vector boson fusion and gluon fusion that subsequently decay to a pair of τ leptons. The data were recorded by the CMS experiment at the LHC...

| description | A study is presented of anomalous HVV interactions of the Higgs boson, including its CP properties.
The study uses Higgs boson candidates produced mainly in vector boson fusion and gluon fusion that
subsequently decay to a pair of τ leptons. The data were recorded by the CMS experiment at the LHC in
2016 at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 35.9 fb−1.
A matrix element technique is employed for the analysis of anomalous interactions. The results are
combined with those from the H → 4l decay channel presented earlier, yielding the most stringent
constraints on anomalous Higgs boson couplings to electroweak vector bosons expressed as effective
cross section fractions and phases: the CP-violating parameter fa3 cosðϕa3Þ¼ð0.00 0.27Þ × 10−3 and
the CP-conserving parameters fa2 cosðϕa2Þ¼ð0.08þ1.04 −0.21 Þ × 10−3, fΛ1 cosðϕΛ1Þ¼ð0.00þ0.53 −0.09 Þ × 10−3,
and fZγ
Λ1 cosðϕZγ
Λ1Þ¼ð0.0þ1.1 −1.3 Þ × 10−3. The current dataset does not allow for precise constraints on CP
properties in the gluon fusion process. The results are consistent with standard model expectations |
