Herwig 7.0 / Herwig++ 3.0 Release Note
Johannes Bellm, Stefan Gieseke, David Grellscheid +13
A major new release of the Monte Carlo event generator Herwig++ (version 3.0) is now available. This release marks the end of distinguishing Herwig++ and HERWIG development and the…
The Non-Linear Higgs Legacy of the LHC Run I
Tyler Corbett, Oscar J. P. Eboli, Dorival Goncalves +3
In the recent paper on "The Higgs Legacy of the LHC Run I" we interpreted the LHC Higgs results in terms of an effective Lagrangian using the SFitter framework. For the on-shell Hi…
Observational Aspects of Galactic Accretion at Redshift 3.3
Michael Rauch, George D. Becker, Martin Haehnelt
We investigate the origin of extragalactic continuum emission and its relation to the stellar population of a recently discovered peculiar z=3.344 Lyman alpha emitter. Based on an…
Probing the Cool Interstellar and Circumgalactic Gas of Three Massive Lensing Galaxies at z=0.4-0.7
Fakhri S. Zahedy, Hsiao-Wen Chen, Michael Rauch +2
We present multi-sightline absorption spectroscopy of cool gas around three lensing galaxies at z=0.4-0.7. These lenses have half-light radii r_e=2.6-8 kpc and stellar masses of lo…
Invisible Higgs Decays to Hooperons in the NMSSM
Anja Butter, Tilman Plehn, Michael Rauch +3
The galactic center excess of gamma ray photons can be naturally explained by light Majorana fermions in combination with a pseudoscalar mediator. The NMSSM provides exactly these…
The Higgs Legacy of the LHC Run I
Tyler Corbett, Oscar J. P. Eboli, Dorival Goncalves +3
Based on Run I data we present a comprehensive analysis of Higgs couplings. For the first time this SFitter analysis includes independent tests of the Higgs-gluon and top Yukawa co…
ZZ production at high transverse momenta beyond NLO QCD
Francisco Campanario, Michael Rauch, Sebastian Sapeta
We study the production of the four-lepton final state , predominantly produced by a pair of electroweak Z bosons, ZZ. Using the LoopSim method, we merge NLO QCD r…
A Close Comparison between Observed and Modeled Lyα Lines for z ~ 2.2 Lyman Alpha Emitters
Takuya Hashimoto, Anne Verhamme, Masami Ouchi +7
We present the results of a Lya profile analysis of 12 Lya emitters (LAEs) at z = 2.2 with high-resolution Lya spectra. We find that all 12 objects have a Lya profile with the main…
DES J0454-4448: Discovery of the First Luminous z > 6 Quasar from the Dark Energy Survey
S. L. Reed, R. G. McMahon, M. Banerji +59
We present the first results of a survey for high redshift, z 6, quasars using izY multi-colour photometric observations from the Dark Energy Survey (DES). Here we report the…
Two bright z > 6 quasars from VST ATLAS and a new method of optical plus mid-infra-red colour selection
A. C. Carnall, T. Shanks, B. Chehade +6
We present the discovery of two z > 6 quasars, selected as i band dropouts in the VST ATLAS survey. Our first quasar has redshift, z = 6.31 \pm 0.03, z band magnitude, z_AB = 19.63…
