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 $m_{\rm H}$ values between 115 and 130 GeV. The best fit of the observed $H \rightarrow \tau \tau$ signal cross section for $m_{H} = 125$ 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.

png pdf | Figure 2: Observed and predicted distributions for the visible $\tau$ mass, $m_{vis}^{\tau_h}$, in the $\mu\tau_h$ channel after the baseline selection. The yields predicted for the $Z\rightarrow\tau\tau$, $Z\rightarrow\mu\mu$, electroweak, $t\bar{t}$, and QCD multijet background contributions correspond to the result of the final fit. The $Z\rightarrow\tau\tau$ 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 $\tau$ built from one charged hadron and photons peaks near the mass of the intermediate $\rho(770)$ resonance; the mass distribution of the $\tau$ built from three charged hadrons peaks around the mass of the intermediate $a_1(1260)$ resonance. The $\tau$ 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 $e^{\pm}\nu\nu$ and $\mu^{\pm}\nu\nu$, respectively, and for which the electron or muon is misidentified as a $\tau$. The electroweak background contribution is dominated by $W+jets$ production. In most selected $W+jets$, $t\bar{t}$, and QCD multijet events, a jet is misidentified as a $\tau$. 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. | |

png pdf | Figure 4: Event categories for the $LL'$ channels. The $p_T^{\tau\tau}$ variable is the transverse momentum of the Higgs boson candidate. In the definition of the VBF-tagged categories, $\Delta\eta_{jj}$ is the difference in pseudorapidity between the two highest-$p_T$ jets, and $m_{jj}$ their invariant mass. In the $ee$ and $\mu\mu$ channels, events with two jets are not required to fulfil any additional VBF tagging criteria. For the analysis of the 7 TeV $e\tau_h$ and $\mu\tau_h$ data, the loose and tight VBF-tagged categories are merged into a single VBF-tagged category. In the $e\tau_h$ channel, the MET is required to be larger than 30 GeV in the 1-jet category. Therefore, the high-$p_T^{\tau}$ category is not used and is accordingly crossed out. | |

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. | |
