Abstract

Tau leptons raise challenges for analysis at hadron colliders but also hold promise for sensitivity to exotic phenomena. Higgs and Supersymmetry models in particular predict enhanced couplings to the third generation particles due to the heavy top mass and appreciable slepton mixing. To escape overwhelming hadronic backgrounds at the Tevatron and LHC, lepton-based searches for exotics are performed. Inclusion of tau triggers and dedicated reconstruction of hadronic tau decays allows extended sensitivity to previously uncovered regions of exotics parameter space. In this talk, I present the status and plans for this analysis program with results and projections from CDF and CMS.Jets and missing ET are expected to play critical roles in finding physics beyond the Standard Model, such as supersymmetry, extra dimensions, and quark compositeness, at the Large Hadron Collider (LHC). I will discuss reconstruction of jets and missing ET in the CMS and ATLAS experiments, and give review on new physics searches with jets and missing ET at the LHC.
