 The Decay of the Standard Model Higgs after Inflation / Figueroa, Daniel G ; Garcia-Bellido, Juan ; Torrenti, Francisco 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 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.
