 Supersymmetric branes on curved spaces and fluxes / Triendl, Hagen (CERN) We discuss general supersymmetric brane configurations in flux backgrounds of string and M-theory and derive a necessary condition for the worldvolume theory to be supersymmetric on a given curved manifold. This condition resembles very much the conditions found from coupling a supersymmetric field theory to off-shell supergravity but can be derived in any dimension and for up to sixteen supercharges.

 Scale invariant Volkov-Akulov Supergravity / Ferrara, S (CERN ; INFN, Frascati ; UCLA) ; Porrati, M (CERN ; New York U., CCPP) ; Sagnotti, A (CERN ; INFN, Pisa) A scale invariant Goldstino theory coupled to Supergravity is obtained as a standard supergravity dual of a rigidly scale invariant higher--curvature Supergravity with a nilpotent chiral scalar curvature. The bosonic part of this theory describes a massless scalaron and a massive axion in a de Sitter Universe.. arXiv:1508.02939; CERN-PH-TH-2015-193.- 2015 - 7 p. - Published in : Phys. Lett.

 Putting a Stop to di-Higgs Modifications / Batell, Brian (CERN) ; McCullough, Matthew (CERN) ; Stolarski, Daniel (CERN) ; Verhaaren, Christopher B (Maryland U.) Pair production of Higgs bosons at hadron colliders is an enticing channel to search for new physics. New colored particles that couple strongly to the Higgs, such as those most often called upon to address the hierarchy problem, provide well motivated examples in which large enhancements of the di-Higgs rate are possible, at least in principle.

 Lepton Flavour Violating top decays at the LHC / Davidson, Sacha (Lyon, IPN ; Lyon U.) ; Mangano, Michelangelo L (CERN) ; Perries, Stephane (Lyon, IPN ; Lyon U.) ; Sordini, Viola (Lyon, IPN ; Lyon U.) We consider lepton flavour violating decays of the top quark, mediated by four-fermion operators. We compile constraints on a complete set of SU(3)*U(1)-invariant operators, arising from their loop contributions to rare decays and from HERA's single top search.

 Heavy concerns about the light axino explanation of the 3.5 keV X-ray line / Colucci, Stefano (Bonn U.) ; Dreiner, Herbi K (Bonn U.) ; Staub, Florian (CERN) ; Ubaldi, Lorenzo (Tel Aviv U.) An unidentified 3.5 keV line from X-ray observations of galaxy clusters has been reported recently. Although still under scrutiny, decaying dark matter could be responsible for this signal.

 N=4 Supersymmetric AdS5 Vacua and their Moduli Spaces / Louis, Jan (Hamburg U. ; Hamburg U., Dept. Math.) ; Triendl, Hagen (CERN) ; Zagermann, Marco (QUEST, Hannover ; Hannover U.) We classify the N=4 supersymmetric AdS5 backgrounds that arise as solutions of five-dimensional N=4 gauged supergravity. We express our results in terms of the allowed embedding tensor components and identify the structure of the associated gauge groups.

 Dark matter scenarios in a constrained model with Dirac gauginos / Goodsell, Mark D (UPMC, Paris (main) ; Paris, LPTHE) ; Krauss, Manuel E (Wurzburg U.) ; Müller, Tobias (Wurzburg U.) ; Porod, Werner (Wurzburg U.) ; Staub, Florian (CERN) We perform the first analysis of Dark Matter scenarios in a constrained model with Dirac Gauginos. The model under investigation is the Constrained Minimal Dirac Gaugino Supersymmetric Standard model (CMDGSSM) where the Majorana mass terms of gauginos vanish.

 Charged-Lepton Mixing and Lepton Flavor Violation / Guadagnoli, Diego (Annecy, LAPTH) ; Lane, Kenneth (Boston U. ; CERN) We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in B-meson decays.

 Parton distributions with threshold resummation / Bonvini, Marco (Oxford U., Theor. Phys.) ; Marzani, Simone (MIT, Cambridge, CTP) ; Rojo, Juan (Oxford U., Theor. Phys.) ; Rottoli, Luca (Oxford U., Theor. Phys.) ; Ubiali, Maria (Cambridge U.) ; Ball, Richard D (U. Edinburgh (main) ; CERN) ; Bertone, Valerio (CERN) ; Carrazza, Stefano (Milan U. ; INFN, Milan) ; Hartland, Nathan P (Oxford U., Theor. Phys.) We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNLL accuracy respectively, suitable for use in conjunction with any QCD calculation in which threshold resummation is included at the level of partonic cross sections. These resummed PDF sets, based on the NNPDF3.0 analysis, are extracted from deep-inelastic scattering, Drell-Yan, and top quark pair production data, for which resummed calculations can be consistently used.
