Reconstruction and Identification of Semi-Leptonic Di-Tau Decays in Boosted Topologies at ATLAS — Arno Straessner, Wolfgang Mader, David Kirchmeier, and •Christian Wiel — IKTP, Dresden, Deutschland

The reconstruction of boosted di-tau decays is important in the search for heavy resonances (e.g. Randall-Sundrum gravitons) decaying into a pair of Higgs bosons. Existing reconstruction and identification algorithms for pairs of tau leptons cease to work in the regime of very low spatial separation. Earlier studies showed successfully how to restore a high reconstruction efficiency if both tau leptons decay hadronically. In this talk algorithms for the case where one tau decays hadronically and the other one decays into lighter leptons are presented. The new identification algorithms show promising results by achieving high background rejections and signal efficiencies.
