Abstract: A search is performed for anomalous interactions of the recently discovered Higgs boson using matrix element techniques with the information from its decay to four leptons and from associated Higgs boson production with two quark jets in either vector boson fusion or associated production with a vector boson. The data were recorded by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 38.6 fb$^{-1}$. These data are combined with the data collected at center-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.7 fb$^{-1}$, respectively. All observations are consistent with the expectations for the standard model Higgs boson. | ||

Figure 1:
Illustration of H boson production and decay in three topologies: gluon fusion $\mathrm{g} \mathrm{g} \to \mathrm{ H } \to {\mathrm {V}} {\mathrm {V}} \to 4\ell $ (left); vector boson fusion $ {\mathrm{ q } \mathrm{ q } } \to {\mathrm {V}} {\mathrm {V}} ( {\mathrm{ q } \mathrm{ q } } ) \to \mathrm{ H } ( {\mathrm{ q } \mathrm{ q } } ) \to {\mathrm {V}} {\mathrm {V}} ( {\mathrm{ q } \mathrm{ q } } )$ (middle); and associated production $ {\mathrm{ q } \mathrm{ q } } \to {\mathrm {V}} \to {\mathrm {V}} \mathrm{ H } \to ( {\mathrm {ff}} )\mathrm{ H } \to ( {\mathrm {ff}} ) {\mathrm {V}} {\mathrm {V}} $ (right). In the latter two cases, the production and decay $\mathrm{ H } \to {\mathrm {V}} {\mathrm {V}} $ may be followed by the same four-lepton decay shown in the first case. The five angles shown in blue and the invariant masses of the two vector bosons shown in green fully characterize either the production or the decay chain. The angles are defined in either the H or V boson rest frames [26,33]. |

Table 1:
Summary of the three production categories in the analysis of 2016 data. The discriminants $\mathcal {D}$ are calculated from Eqs.(4) and (5), as discussed in more detail in the text. For each analysis, the appropriate BSM model is considered in the definition of the categories: $f_{a3}=1$, $f_{a2}=1$, $f_{\Lambda 1}=1$, or $f^{{\mathrm{ Z } } \gamma }_{\Lambda 1}=1$. Three observables (abbreviated as obs.) are listed for each analysis and for each category. They are described in more detail later in the text. |

Summary |
We study anomalous interactions of the H boson using novel techniques with a matrix element likelihood approach to simultaneously analyze the $\mathrm{ H }\to4\ell$ decay and associated production with two quark jets. Three categories of events are analyzed, targeting events produced in vector boson fusion, with an associated vector boson, and in gluon fusion, respectively. The data collected at a center-of-mass energy of 13 TeV in Run\,2 of the LHC are combined with the Run\,1 data, collected at 7 and 8 TeV. No deviations from the standard model are observed and constraints are set on the four anomalous $\mathrm{ H }{\mathrm{V}} {\mathrm{V}} $ contributions, including the CP-violation parameter $f_{a3}$, summarized in Table 3. |

The animations scan $f_{a2}$ to illustrate how the expected signal distributions change as a function of $f_{a2}$. For each value of $f_{a2}$, the signal strengths for Higgs production through couplings to fermions $\mu _f$ and bosons $\mu _V$ are set to their best-fit values. The values of $f_{a2}$, $f_{a2}^\text {VBF}$, and $f_{a2}^{\mathrm {V} \mathrm{ H } }$ are recorded on the plots, along with the negative log likelihood. $f_{a2}^\text {VBF}$ and $f_{a2}^{\mathrm {V} \mathrm{ H } }$ are defined using Eq.(2) by analogy with $f_{a2}$, but using the cross sections for the VBF and VH processes, respectively. | |
