| Description | Title: "Searching for new physics in high-mass ditau events at ATLAS" Speaker: Ryan Reece, UCSC host: Robin Erbacher Abstract: "The LHC has brought a new level of sensitivity to possible TeV-scale new physics. Tau leptons can have preferred couplings to possible new physics, including Z' bosons motivated by grand unified theories. Hadronic tau decays are one of the most difficult final states to identify at hadron colliders like the LHC, but ATLAS has multivariate techniques for identifying hadronic tau decays using Boosted Decision Trees and sophisticated calibrations. Tau final states give complex multijet and electroweak background compositions that require data-driven techniques. Results will be presented from searches for Z' bosons in high-mass ditau events at ATLAS." |
