 General squark flavour mixing: constraints, phenomenology and benchmarks / De Causmaecker, Karen (Brussels U., IIHE ; Intl. Solvay Inst., Brussels) ; Fuks, Benjamin (UPMC, Paris (main) ; Paris, LPTHE ; Strasbourg, IPHC ; Strasbourg, IReS) ; Herrmann, Bjoern (Annecy, Lapth) ; Mahmoudi, Farvah (Ecole Normale Supérieure, Paris ; Lyon Observ. ; Lyon U. ; CERN) ; O'Leary, Ben (Wurzburg U.) ; Porod, Werner (Wurzburg U.) ; Sekmen, Sezen (Kyungpook Natl. U.) ; Strobbe, Nadja (Gent U. ; Fermilab) We present an extensive study of non-minimal flavour violation in the squark sector in the framework of the Minimal Supersymmetric Standard Model. We investigate the effects of multiple non-vanishing flavour-violating elements in the squark mass matrices by means of a Markov Chain Monte Carlo scanning technique and identify parameter combinations that are favoured by both current data and theoretical constraints.

 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.

 Stop-Catalyzed Baryogenesis Beyond the MSSM / Katz, Andrey (CERN ; Geneva U., Dept. Theor. Phys. ; Geneva U., CAP) ; Perelstein, Maxim (Cornell U., LEPP) ; Ramsey-Musolf, Michael J (Massachusetts U., Amherst ; Caltech, Kellogg Lab) ; Winslow, Peter (Massachusetts U., Amherst) Non-minimal supersymmetric models that predict a tree-level Higgs mass above the Minimal Supersymmetric Standard Model (MSSM) bound are well motivated by naturalness considerations. Indirect constraints on the stop sector parameters of such models are significantly relaxed compared to the MSSM; in particular, both stops can have weak-scale masses.

 Melting Hadrons, Boiling Quarks / Rafelski, Johann (CERN ; Arizona U.) In the context of the Hagedorn temperature half-centenary I describe our understanding of the hot phases of hadronic matter both below and above the Hagedorn temperature. The first part of the review addresses many frequently posed questions about properties of hadronic matter in different phases, phase transition and the exploration of quark-gluon plasma (QGP).

 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.

 Fiducial cross sections for Higgs boson production in association with a jet at next-to-next-to-leading order in QCD / Caola, Fabrizio (CERN) ; Melnikov, Kirill (KIT, Karlsruhe, TTP) ; Schulze, Markus (CERN) We extend the recent computation of Higgs boson production in association with a jet through next-to-next-to-leading order in perturbative QCD by including decays of the Higgs boson to electroweak vector bosons. This allows us to compute fiducial cross sections and kinematic distributions including realistic selection criteria for the Higgs boson decay products.

We combine the fully-differential NNLO calculation with higher-order resummation in the 0-jettiness resolution variable.

 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.
