Consistent truncations of M-theory for general SU(2) structures / Triendl, Hagen
In seven dimensions any spin manifold admits an SU(2) structure and therefore very general M-theory compactifications have the potential to allow for a reduction to N=4 gauged supergravity. [...]

London ; CERN) ; Guha, S (CERN ; Birla Inst. Tech. Sci.) ; Marrouche, J (Imperial Coll., London) ; Olive, K A (Minnesota U., Theor. Phys. Inst.) ; de Vries, K (Imperial Coll., London) ; Zheng, Jiaming (Minnesota U., Theor. Phys. Inst.)
We discuss the potential impacts on the CMSSM of future LHC runs and possible electron-positron and higher-energy proton-proton colliders, considering searches for supersymmetry via MET events, precision electroweak physics, Higgs measurements and dark matter searches. [...]

T-duality, Quotients and Currents for Non-Geometric Closed Strings / Bakas, Ioannis (Natl. Tech. U., Athens) ; Lust, Dieter (Munich, Max Planck Inst. ; Munich U., ASC ; CERN)
We use the canonical description of T-duality as well as the formulation of T-duality in terms of chiral currents to investigate the geometric and non-geometric faces of closed string backgrounds originating from principal torus bundles with constant H-flux. [...]
