# ${{\boldsymbol H}^{0}}$ SIGNAL STRENGTHS IN DIFFERENT CHANNELS

The ${{\mathit H}^{0}}$ signal strength in a particular final state ${{\mathit x}}{{\mathit x}}$ is given by the cross section times branching ratio in this channel normalized to the Standard Model (SM) value, $\sigma$ $\cdot{}$ B( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ) $/$ ($\sigma$ $\cdot{}$ B( ${{\mathit H}^{0}}$ $\rightarrow$ ${{\mathit x}}{{\mathit x}}$ ))$_{{\mathrm {SM}}}$, for the specified mass value of ${{\mathit H}^{0}}$. For the SM predictions, see DITTMAIER 2011 , DITTMAIER 2012 , and HEINEMEYER 2013A. Results for fiducial and differential cross sections are also listed below.

1  AAD 2016AN perform fits to the ATLAS and CMS data at $\mathit E_{{\mathrm {cm}}}$ = 7 and 8 TeV. The signal strengths for individual production processes are $1.03$ ${}^{+0.16}_{-0.14}$ for gluon fusion, $1.18$ ${}^{+0.25}_{-0.23}$ for vector boson fusion, $0.89$ ${}^{+0.40}_{-0.38}$ for ${{\mathit W}}{{\mathit H}^{0}}$ production, $0.79$ ${}^{+0.38}_{-0.36}$ for ${{\mathit Z}}{{\mathit H}^{0}}$ production, and $2.3$ ${}^{+0.7}_{-0.6}$ for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}^{0}}$ production.
2  AAD 2016AN: The uncertainties represent statistics, experimental systematics, theory systematics on the background, and theory systematics on the signal. The quoted signal strengths are given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.09 GeV. In the fit, relative branching ratios and relative production cross sections are fixed to those in the Standard Model.
3  AALTONEN 2013M combine all Tevatron data from the CDF and D0 Collaborations with up to 10.0 fb${}^{-1}$ and 9.7 fb${}^{-1}$, respectively, of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 1.96 TeV. The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV.
4  AAD 2016K use up to 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV and up to 20.3 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The third uncertainty in the measurement is theory systematics. The signal strengths for individual production modes are $1.23$ $\pm0.14$ ${}^{+0.09}_{-0.08}{}^{+0.16}_{-0.12}$ for gluon fusion, $1.23$ ${}^{+0.28}_{-0.27}{}^{+0.13}_{-0.12}{}^{+0.11}_{-0.09}$ for vector boson fusion, $0.80$ ${}^{+0.31}_{-0.30}$ $\pm0.17$ ${}^{+0.10}_{-0.05}$ for ${{\mathit W}}$ $/$ ${{\mathit Z}}{{\mathit H}^{0}}$ production, and $1.81$ ${}^{+0.52}_{-0.50}{}^{+0.58}_{-0.55}{}^{+0.31}_{-0.12}$ for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}^{0}}$ production. The quoted signal strengths are given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.36 GeV.
5  AAD 2015P measure total and differential cross sections of the process ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}^{0}}{{\mathit X}}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV with 20.3 fb${}^{-1}$. ${{\mathit \gamma}}{{\mathit \gamma}}$ and 4 ${{\mathit \ell}}$ final states are used. ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit H}^{0}}{{\mathit X}}{)}$ = $33.0$ $\pm5.3$ $\pm1.6$ pb is given. See their Figs. 2 and 3 for data on differential cross sections.
6  KHACHATRYAN 2015AM use up to 5.1 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV and up to 19.7 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The third uncertainty in the measurement is theory systematics. Fits to each production mode give the value of $0.85$ ${}^{+0.19}_{-0.16}$ for gluon fusion, $1.16$ ${}^{+0.37}_{-0.34}$ for vector boson fusion, $0.92$ ${}^{+0.38}_{-0.36}$ for ${{\mathit W}}{{\mathit H}^{0}}$ , ${{\mathit Z}}{{\mathit H}^{0}}$ production, and $2.90$ ${}^{+1.08}_{-0.94}$ for ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}^{0}}$ production.
7  AAD 2013AK use 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV and 20.7 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. The combined signal strength is based on the ${{\mathit \gamma}}{{\mathit \gamma}}$ , ${{\mathit Z}}$ ${{\mathit Z}^{*}}$ $\rightarrow$ 4 ${{\mathit \ell}}$ , and ${{\mathit W}}$ ${{\mathit W}^{*}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \nu}}{{\mathit \ell}}{{\mathit \nu}}$ channels. The quoted signal strength is given for ${\mathit m}_{{{\mathit H}^{0}}}$ = 125.5 GeV. Reported statistical error value modified following private communication with the experiment.

An excess of events over background with a local significance of 5.9 $\sigma$ is observed at ${\mathit m}_{{{\mathit H}^{0}}}$ = 126 GeV.

An excess of events over background with a local significance of 5.0$~\sigma$ is observed at about ${\mathit m}_{{{\mathit H}^{0}}}$ = 125 GeV. The combined signal strength is based on the ${{\mathit \gamma}}{{\mathit \gamma}}$ , ${{\mathit Z}}{{\mathit Z}^{*}}$ , ${{\mathit W}}{{\mathit W}^{*}}$ , ${{\mathit \tau}^{+}}{{\mathit \tau}^{-}}$ , and ${{\mathit b}}{{\overline{\mathit b}}}$ channels.
