| Title: Prospects for the Type II Two-Higgs Doublet Model from the LHC Higgs Discovery |
| Abstract: In light of the recent discovery of the Higgs boson by the LHC experiments, we interpret the observed excess as the lighter neutral real scalar of a CP-conserving, Type II 2HDM and discuss the discovery prospects of new states under certain scenarios. We perform a likelihood analysis of LHC Higgs data to extract the light neutral Higgs couplings and infer the heavy neutral Higgs couplings: from this, we discuss the current exclusion bounds and future prospects, which are complementary to MSSM Higgs searches. We also discuss the potential effects on our results from forthcoming light Higgs measurements. |

| Title: Tentative observation of a gamma-ray line at Fermi-LAT |
Abstract: Using 43 months of public gamma-ray data from the Fermi Large Area Telescope, we find in regions close to the galactic center at energies of 130 GeV a 4.6 sigma excess that is not inconsistent with a gamma-ray line from dark matter annihilation. When taking into account the look-elsewhere effect, the significance of the observed signature is 3.3 sigma. If interpreted in terms of dark matter particles annihilating into a photon pair, the observations imply a partial annihilation cross-section of about 10^-27 cm^3 s^-1 and a dark matter mass around 130 GeV. We will focus on details of the statistical analysis and possible caveats, and comment on future prospects. |
