The Muon Collider as a $H/A$ factory / Eichten, Estia (Fermilab) ; Martin, Adam (CERN ; Notre Dame U.)
We show that a muon collider is ideally suited for the study of heavy H/A scalars, cousins of the Higgs boson found in two-Higgs doublet models and required in supersymmetric models. [...]

The Charged Higgs Boson Mass of the MSSM in the Feynman-Diagrammatic Approach / Frank, M (Karlsruhe U., ITP) ; Galeta, L (Cantabria Inst. of Phys.) ; Hahn, T (Munich, Max Planck Inst.) ; Heinemeyer, S (Cantabria Inst. of Phys.) ; Hollik, W (Munich, Max Planck Inst.) ; Rzehak, H (CERN) ; Weiglein, G (DESY)
The interpretation of the Higgs signal at \sim 126 GeV within the Minimal Supersymmetric Standard Model (MSSM) depends crucially on the predicted properties of the other Higgs states of the model, as the mass of the charged Higgs boson, MH+-. [...]

This letter details and discusses the next-to-leading order QCD corrections to $t$-channel electro-weak $W^+ b j$ production, where finite top-width effects are consistently taken into account. [...]

How well do we need to measure the Higgs boson mass and self-coupling? / Gupta, Rick S (Barcelona, IFAE) ; Rzehak, Heidi (CERN) ; Wells, James D (CERN ; Michigan U.)
Much of the discussion regarding future measurements of the Higgs boson mass and self-coupling is focussed on how well various collider options can do. [...]
