 A Theta lift representation for the Kawazumi-Zhang and Faltings invariants of genus-two Riemann surfaces / Pioline, Boris (CERN and 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 ; Delgado, A ; Martin, A ; Ostdiek, B 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 ; Hirschi, V ; Pagani, D ; Shao, H -S ; Zaro, M 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 ; Fox, Patrick J ; Kahn, Yonatan ; McCullough, Matthew 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 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.

 The pMSSM10 after LHC Run 1 / de Vries, K J ; Bagnaschi, E A ; Buchmueller, O ; Cavanaugh, R ; Citron, M ; De Roeck, A ; Dolan, M J ; Ellis, J R ; Flaecher, H ; Heinemeyer, S 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.

 Combining LEP and LHC to bound the Higgs Width / Englert, Christoph (Glasgow U.) ; McCullough, Matthew (CERN) ; Spannowsky, Michael (Durham U., IPPP) The correlation of on- and off-shell Higgs boson production at the LHC in $gg \to h^* \to ZZ$ to bound the Higgs width, under specific model-dependent assumptions, has recently received a lot of attention.

 Physics at the e+ e- Linear Collider / Moortgat-Pick, G (Hamburg U., Inst. Theor. Phys. II ; DESY) ; Baer, H (Oklahoma U.) ; Battaglia, M (UC, Santa Cruz) ; Belanger, G (Annecy, LAPTH) ; Fujii, K (KEK, Tsukuba) ; Kalinowski, J (Warsaw U.) ; Heinemeyer, S (Cantabria Inst. of Phys.) ; Kiyo, Y (Juntendo U.) ; Olive, K (Minnesota U., Theor. Phys. Inst.) ; Simon, F (Munich, Max Planck Inst.) et al. A comprehensive review of physics at an e+e- Linear Collider in the energy range of sqrt{s}=92 GeV--3 TeV is presented in view of recent and expected LHC results, experiments from low energy as well as astroparticle physics.The report focuses in particular on Higgs boson, Top quark and electroweak precision physics, but also discusses several models of beyond the Standard Model physics such as Supersymmetry, little Higgs models and extra gauge bosons.
