Abstract: A search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 fb$ ^{-1}$ at a centre-of-mass energy of 7 TeV, and 19.7 fb$ ^{-1}$ at 8 TeV. Each tau lepton decays hadronically or leptonically to an electron or a muon, leading to six different final states for the tau-lepton pair, all considered in this analysis. An excess of events is observed over the expected background contributions, with a local significance larger than 3 standard deviations for $ m_{\mathrm{H}} $ values between 115 and 130 GeV. The best fit of the observed $ \mathrm{H} \to \tau \tau $ signal cross section for $ m_{\mathrm{H}} $ = 125 GeV is 0.78 $\pm$ 0.27 times the standard model expectation. These observations constitute evidence for the 125 GeV Higgs boson decaying to a pair of tau leptons. | ||

Figure 2:
Observed and predicted distributions for the visible $ { {\tau }_{\rm h}} $ mass, $ {m_\text {vis}} ^{ { {\tau }_{\rm h}} }$, in the $ {{\mu }} { {\tau }_{\rm h}} $ channel after the baseline selection described in section Event Selection. The yields predicted for the $ {\mathrm {Z}}\to \tau \tau $, $ {\mathrm {Z}}\to \mu \mu $, electroweak, $ {\mathrm {t}\overline {\mathrm {t}}} $, and QCD multijet background contributions correspond to the result of the final fit presented in Section Results. The $ {\mathrm {Z}}\to \tau \tau $ contribution is then split according to the decay mode reconstructed by the hadron-plus-strips algorithm as shown in the legend. The mass distribution of the $ { {\tau }_{\rm h}} $ built from one charged hadron and photons peaks near the mass of the intermediate $ {\rho \mathrm {(770)}}$ resonance; the mass distribution of the $ { {\tau }_{\rm h}} $ built from three charged hadrons peaks around the mass of the intermediate $ {\mathrm {a_1(1260)}}$ resonance. The $ { {\tau }_{\rm h}} $ built from one charged hadron and no photons are reconstructed with the $\pi ^\pm $ mass, assigned to all charged hadrons by the PF algorithm, and constitute the main contribution to the third bin of this histogram. The first two bins correspond to $\tau ^\pm $ leptons decaying into $ {\mathrm {e}}^\pm \nu \nu $ and $ {{\mu }}^\pm \nu \nu $, respectively, and for which the electron or muon is misidentified as a $ { {\tau }_{\rm h}} $. The electroweak background contribution is dominated by $ {\mathrm {W}}+\text {jets}$ production. In most selected $ {\mathrm {W}}+ \text {jets}$, $ {\mathrm {t}\overline {\mathrm {t}}} $, and QCD multijet events, a jet is misidentified as a $ { {\tau }_{\rm h}} $. The ``bkg. uncertainty'' band represents the combined statistical and systematic uncertainty in the background yield in each bin. The expected contribution from the SM Higgs signal is negligible. |

The distribution obtained for a simulated sample of $ {\mathrm {Z}}\to \tau \tau $ events (shaded histogram) is compared to the one obtained for a signal sample with a SM Higgs boson of mass $ {m_{ {\mathrm {H}} }}$ = 125 GeV (open histogram). |

Figure 4:
Event categories for the $LL'$ channels. The $ { {p_{\mathrm {T}}} ^{\tau \tau }} $ variable is the transverse momentum of the Higgs boson candidate. In the definition of the VBF-tagged categories, $ {| {\Delta \eta _\mathrm {jj}} | }$ is the difference in pseudorapidity between the two highest-$p_{\mathrm {T}}$ jets, and $ {m_\mathrm {jj}} $ their invariant mass. In the $ {{\mu }} {{\mu }}$ and $ {\mathrm {e}} {\mathrm {e}}$ channels, events with two or more jets are not required to fulfil any additional VBF tagging criteria. For the analysis of the 7 TeV $ {\mathrm {e}} { {\tau }_{\rm h}} $ and $ {{\mu }} { {\tau }_{\rm h}} $ data, the loose and tight VBF-tagged categories are merged into a single VBF-tagged category. In the $ {\mathrm {e}} { {\tau }_{\rm h}} $ channel, the $E_{\mathrm {T}}^{\text {miss}}$ is required to be larger than 30 GeV in the 1-jet category. Therefore, the high-$ {p_{\mathrm {T}}} ^{ { {\tau }_{\rm h}} }$ category is not used and is accordingly crossed out. The term ``baseline'' refers to the baseline selection described in section Event Selection. |

Observed and predicted distributions in the $ {{\mu }} { {\tau }_{\rm h}} $ channel after the baseline selection, for (a) the transverse momentum of the Higgs boson candidates and (b) the transverse momentum of the $ { {\tau }_{\rm h}} $. The yields predicted for the various background contributions correspond to the result of the final fit presented in Section {sec:results}. The electroweak background contribution includes events from $ {\mathrm {W}}+ \text {jets}$, diboson, and single-top-quark production. The ``bkg. uncertainty'' band represents the combined statistical and systematic uncertainty in the background yield in each bin. In each plot, the bottom inset shows the ratio of the observed and predicted numbers of events. The expected contribution from the SM Higgs signal is negligible. |

Combined observed and predicted distributions of the decimal logarithm $\log(S/(S+B))$ in each bin of the final $ {m_{ {\tau } {\tau }}} $, $ {m_\text {vis}} $, or discriminator distributions obtained in all event categories and decay channels, with $S/(S+B)$ denoting the ratio of the predicted signal and signal-plus-background event yields in each bin. The normalization of the predicted background distributions corresponds to the result of the global fit. The signal distribution, on the other hand, is normalized to the SM prediction ($\mu = 1$). The inset shows the corresponding difference between the observed data and expected background distributions, together with the signal distribution for a SM Higgs boson at $ {m_{ {\mathrm {H}} }}$ = 125 GeV. The distribution from SM Higgs boson events in the $ {\mathrm {W}} {\mathrm {W}}$ decay channel does not significantly contribute to this plot. |

Scan of the negative log-likelihood difference, $-2\Delta \ln\mathcal {L}$, as a function of $ {m_{ {\mathrm {H}} }} $ (a) and as a function of $ {\kappa _\mathrm {V}} $ and $ {\kappa _\mathrm {f}} $ (b). For each point, all nuisance parameters are profiled. For the likelihood scan as a function of $ {m_{ {\mathrm {H}} }} $, the background-only hypothesis includes the $ {\mathrm {p}} {\mathrm {p}}\to {\mathrm {H}} \text {(125 GeV)}\to {\mathrm {W}} {\mathrm {W}}$ process for every value of $ {m_{ {\mathrm {H}} }} $. The observation (solid line) is compared to the expectation (dashed line) for a SM Higgs boson with mass $ {m_{ {\mathrm {H}} }} $ = 125 GeV. For the likelihood scan as a function of $ {\kappa _\mathrm {V}} $ and $ {\kappa _\mathrm {f}} $, the $ {\mathrm {H}}\to {\mathrm {W}} {\mathrm {W}}$ contribution is treated as a signal process. |
