 ZZ production at high transverse momenta beyond NLO QCD / Campanario, Francisco (Valencia U., IFIC ; Karlsruhe, Inst. Technol.) ; Rauch, Michael (Karlsruhe, Inst. Technol.) ; Sapeta, Sebastian (CERN) We study the production of the four-lepton final state $l^+ l^- l^+ l^-$, predominantly produced by a pair of electroweak Z bosons, ZZ.

 The Higgs boson, Supersymmetry and Dark Matter: Relations and Perspectives / Arbey, Alexandre (Lyon U. ; Lyon Observ. ; Lyon, Ecole Normale Superieure ; CERN) ; Battaglia, Marco (UC, Santa Cruz, Inst. Part. Phys. ; CERN) ; Mahmoudi, Farvah (Lyon Observ. ; Lyon, Ecole Normale Superieure ; CERN) The discovery of a light Higgs boson at the LHC opens a broad program of studies and measurements to understand the role of this particle in connection with New Physics and Cosmology.

 The Decay of the Standard Model Higgs after Inflation / Figueroa, Daniel G (CERN ; Geneva U.) ; Garcia-Bellido, Juan (Madrid, IFT) ; Torrenti, Francisco (CERN ; Madrid, IFT) We study the non-perturbative dynamics of the Standard Model (SM) after inflation, in the regime where the SM is decoupled from (or weakly coupled to) the inflationary sector.

 A Theta lift representation for the Kawazumi-Zhang and Faltings invariants of genus-two Riemann surfaces / Pioline, Boris (CERN ; Paris, LPTHE) The Kawazumi-Zhang invariant $\varphi$ for compact genus-two Riemann surfaces was recently shown to be a eigenmode of the Laplacian on the Siegel upper half-plane, away from the separating node.

 Dirac Triplet Extension of the MSSM / Alvarado, C (Notre Dame U.) ; Delgado, A (Notre Dame U. ; CERN) ; Martin, A (Notre Dame U.) ; Ostdiek, B (Notre Dame U.) In this paper we explore extensions of the Minimal Supersymmetric Standard Model involving two $SU(2)_L$ triplet chiral superfields that share a superpotential Dirac mass yet only one of which couples to the Higgs fields.

 Halo-Independent Direct Detection Analyses Without Mass Assumptions / Anderson, Adam J (MIT, LNS) ; Fox, Patrick J (Fermilab) ; Kahn, Yonatan (MIT, LNS) ; McCullough, Matthew (CERN) Results from direct detection experiments are typically interpreted by employing an assumption about the dark matter velocity distribution, with results presented in the $m_\chi-\sigma_n$ plane.

 The Physics Landscape after the Higgs Discovery at the LHC / Ellis, John (King's Coll. London ; CERN) What is the Higgs boson telling us? What else is there, maybe supersymmetry and/or dark matter? How do we find it? These are now the big questions in collider physics that I discuss in this talk, from a personal point of view.. arXiv:1504.03654 ; KCL-PH-TH-2015-19 ; LCTS-2015-09 ; CERN-PH-TH-2015-085. - 2015. - 12 p.
