LHC probes the hidden sector
Joerg Jaeckel, Martin Jankowiak, Michael Spannowsky
In this note we establish LHC limits on a variety of benchmark models for hidden sector physics using 2011 and 2012 data. First, we consider a "hidden" U(1) gauge boson under which…
Polishing a shiny Higgs with matrix elements
Jeppe R. Andersen, Christoph Englert, Michael Spannowsky
After the recent discovery of a Standard Model Higgs boson-like particle at the LHC, the question of its couplings to known and unknown matter is eminent. In this letter, we presen…
Finding top quarks with shower deconstruction
Davison E. Soper, Michael Spannowsky
We develop a new method for tagging jets produced by hadronically decaying top quarks. The method is an application of shower deconstruction, a maximum information approach that wa…
New Physics in LHC Higgs boson pair production
Matthew J. Dolan, Christoph Englert, Michael Spannowsky
Multi-Higgs production provides a phenomenologically clear window to the electroweak symmetry breaking sector. We perform a comprehensive and comparative analysis of new electrowea…
Partially (in)visible Higgs decays at the LHC
Christoph Englert, Michael Spannowsky, Chris Wymant
Both Atlas and CMS have reported a discovery of a Standard Model-like Higgs boson of mass around 125 GeV. Consistency with the Standard Model implies the non-observation of non…
The dependency of boosted tagging algorithms on the event colour structure
Kiran Joshi, Andrew D. Pilkington, Michael Spannowsky
The impact of event colour structure on the performance of the Johns-Hopkins, CMS, HEPToptagger and N-Subjettiness algorithms is investigated by studying colour singlet and colour…
Release Note -- Vbfnlo-2.6.0
K. Arnold, J. Bellm, G. Bozzi +16
Vbfnlo is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), double and triple vector boson (plus jet) production in hadronic collisions a…
On jet mass distributions in Z+jet and dijet processes at the LHC
Mrinal Dasgupta, Kamel Khelifa-Kerfa, Simone Marzani +1
The mass distribution of jets produced in hard processes at the LHC plays an important role in several jet substructure related studies involving both Standard Model and BSM physic…
Higgs self-coupling measurements at the LHC
Matthew J. Dolan, Christoph Englert, Michael Spannowsky
Both the ATLAS and CMS collaborations have reported a Standard Model Higgs-like excess at around GeV. If an SM-like Higgs particle is discovered in this particular mass…
Stop searches in 2012
Tilman Plehn, Michael Spannowsky, Michihisa Takeuchi
For this year's 8TeV run of the LHC we lay out different strategies to search for scalar top pairs. We show results for the hadronic and for the semi-leptonic channels based on had…
Constraining the Unhiggs with LHC data
Christoph Englert, Dorival Goncalves, Michael Spannowsky +1
Recent measurements by the ATLAS and CMS experiments have excluded the Standard Model Higgs boson in the high mass region, even if it is produced with a significantly smaller cross…
Measuring Higgs CP and couplings with hadronic event shapes
Christoph Englert, Michael Spannowsky, Michihisa Takeuchi
Experimental falsification or validation of the Standard Model of Particle Physics involves the measurement of the CP quantum number and couplings of the Higgs boson. Both ATLAS an…
Unconstraining the Unhiggs
Christoph Englert, Michael Spannowsky, David Stancato +1
We investigate whether or not perturbative unitarity is preserved in the Unhiggs model for the scattering process of heavy quarks and longitudinal gauge bosons $\bar q q \to V_L^+…
Jet Substructure at the Tevatron and LHC: New results, new tools, new benchmarks
A. Altheimer, S. Arora, L. Asquith +68
In this report we review recent theoretical progress and the latest experimental results in jet substructure from the Tevatron and the LHC. We review the status of and outlook for…
