High Energy Physcis Seminar-Kanishk Rao-Top-quarks, Dark Matter, and BSM Higgs at CDF and ATLAS We present searches in the top-quark, dark matter and BSM Higgs sectors at the CDF and ATLAS experiments. We present a search for fourth generation quarks at the ATLAS detector using a novel W identification method. We search for a new particle resonance that might explain the CDF observed top-quark asymmetry at CDF and ATLAS. We also describe a new method, 'basis-limits',which allows for powerful reinterpretation of experimental results without the need for experiment-specific tools, which are usually not available publicly. Finally, we discuss BSM scenarios for the newly discovered boson at the LHC, specifically in the 2 Higgs Doublet Model framework. We present a search for such a model at CDF and prospects at the LHC.

High Energy Theory Seminar - IAS - David Skinner, University of Cambridge; IAS - Twistor Strings for N=8 Supergravity I'll explain a new way of looking at 4d supergravity --- as a theory of holomorphic maps into Penrose's twistor space. Allowing twistor space to have N fermionic directions, the theory is anomaly free when N=8. Via the Penrose transform, the vertex operators correspond to an N=8 Einstein supergravity multiplet. In the first instance, the model describes SO(8) gauged supergravity in AdS_4. Upon taking the flat space, ungauged limit, the complete classical S-matrix is recovered from worldsheet correlation functions.
