Establishment of the Standard Model H → τ τ signal in LHC Run II — •Raphael Friese, Roger Wolf, Andrew Gilbert, and Günter Quast — Institut für Experimentelle Kernphysik, Karlsruher Institut für Technologie (KIT)

The Standard Model H → τ τ analysis of the CMS experiment in the LHC Run I observed the presence of a Higgs boson decaying to a pair of two τ-leptons with a significance of 3.2 σ, with 3.7 σ expectation. The LHC run I took place in the years 2011 and 2012, incorporating an integrated luminosity of 24.9 fb⁻¹ at center-of-mass energies of 7 and 8 TeV,

The analysis presented here incorporates an integrated luminosity of 12.9 fb⁻¹ at a center-of-mass energy of 13 TeV, recorded in 2016 by the CMS experiment. The analysis covers the four most significant di-τ final states. It gets its significance from a classical approach doing cut-based event categorization. It is one step towards the full establishment of the H → τ τ coupling with a significance of 5 σ the CMS collaboration is aiming to establish with the full dataset of 2016.
