Search for new physics in final states with one tau and missing transverse energy with CMS — •Klaas Padeken, Kerstin Hoepfner, Viktor Kutzner, and Thomas Hebbeker — III Phys. Inst. A, Aachen

The first search for new physics beyond the Standard Model in √s=13 TeV pp events with one hadronically decaying tau and missing transverse energy is presented. The tau channel is of theoretical interest in light of the huge difference in mass of taus w.r.t. electrons and muons.

For this search the tau reconstruction has been extended to high energies and the first taus with TeV energies have been reconstructed and observed.

The results will be interpreted in terms of a new heavy charged vector boson W’, which decays into a tau and a neutrino and in the framework of a non-universal gauge interaction model with the aim to explain the heaviness of the third generation fermions, with respect to the light first and second generation. The analysis is performed with the 2015 dataset recorded with CMS at a center of mass energy of √s=13 TeV.
