Search for signatures with top, bottom, tau and exotics

The Standard Model (SM) of particle physics is a sensational success, especially since the discov- ery of the 125 GeV Higgs boson. However, there are still several open questions that the Standard Model doesnâ??t address, like the nature of dark matter and dark energy, the matter-antimatter asym- metry, the neutrino oscillations, the inconsistency with the general relativity and the hierarchy problem. Theories Beyond the Standard Model (BSM), such as Supersymmetry, Little and Com- posite Higgs, Extra-Dimensions, Extended Gauge models, Technicolor, Left-Right symmetric models, and many other BSM scenarios are trying to answer these questions. In these proceed- ings we present the most recent results for searches Beyond the Standard Model at the LHC by the ATLAS and CMS experiments, focusing on signatures with top, bottom, tau and exotics. The data are found to be consistent with the Standard Model. The non-observation of a signal permits to set limits at the 95pct confidence level on the production cross section times branching ratio and on the masses of the hypothesized new particles for appropriate benchmark models.
