ZZ production at high transverse momenta beyond NLO QCD / Campanario, Francisco ; Rauch, Michael ; Sapeta, Sebastian
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. [...]

Electroweak and QCD corrections to top-pair hadroproduction in association with heavy bosons / Frixione, S (CERN) ; Hirschi, V (SLAC) ; Pagani, D (Louvain U., CP3) ; Shao, H -S (CERN) ; Zaro, M (UPMC, Paris (main) ; Paris U., VI-VII)
We compute the contribution of order $\alpha_S^2\alpha^2$ to the cross section of a top-antitop pair in association with at least one heavy Standard Model boson -- $Z$, $W^\pm$, and Higgs -- by including all effects of QCD, QED, and weak origin and by working in the automated MadGraph5_aMC@NLO framework.

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..

The pMSSM10 after LHC Run 1 / de Vries, K J (Imperial Coll., London) ; Bagnaschi, E A (DESY) ; Buchmueller, O (Imperial Coll., London) ; Cavanaugh, R (Fermilab ; Illinois U.) ; Citron, M (Imperial Coll., London) ; De Roeck, A (CERN ; Antwerp U.) ; Dolan, M J (SLAC) ; Ellis, J R (CERN ; King’s College London) ; Flaecher, H (Bristol U.) ; Heinemeyer, S (Madrid, Inst. Estructura Materia) et al.
We present a frequentist analysis of the parameter space of the pMSSM10, in which the following 10 soft SUSY-breaking parameters are specified independently at the mean scalar top mass scale Msusy = Sqrt[M_stop1 M_stop2]: the gaugino masses M_{1,2,3}, the 1st-and 2nd-generation squark masses M_squ1 = M_squ2, the third-generation squark mass M_squ3, a common slepton mass M_slep and a common trilinear mixing parameter A, the Higgs mixing parameter mu, the pseudoscalar Higgs mass M_A and tan beta.
