Higgs Self-Coupling Measurements at a 100 TeV Hadron Collider
Alan J. Barr, Matthew J. Dolan, Christoph Englert +2
An important physics goal of a possible next-generation high-energy hadron collider will be precision characterisation of the Higgs sector and electroweak symmetry breaking. A cruc…
Constraining Dark Sectors at Colliders: Beyond the Effective Theory Approach
Philip Harris, Valentin V. Khoze, Michael Spannowsky +1
We outline and investigate a set of benchmark simplified models with the aim of providing a minimal simple framework for an interpretation of the existing and forthcoming searches…
Off-Shell Higgs Coupling Measurements in BSM scenarios
Christoph Englert, Yotam Soreq, Michael Spannowsky
Proposals of measuring the off-shell Higgs contributions and first measurements at the LHC have electrified the Higgs phenomenology community for two reasons: Firstly, probing inte…
Di-Higgs phenomenology: The forgotten channel
Christoph Englert, Frank Krauss, Michael Spannowsky +1
Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof) that directly relate to the mechanism of electroweak symmetry breaking. Multi-…
Effective Theories and Measurements at Colliders
Christoph Englert, Michael Spannowsky
If the LHC run 2 will not provide conclusive hints for new resonant Physics beyond the Standard Model, dedicated and consistent search strategies at high momentum transfers will be…
Scattering of Dark Particles with Light Mediators
Davison E. Soper, Michael Spannowsky, Tim M. P. Tait +1
We present a treatment of the high energy scattering of dark Dirac fermions from nuclei, mediated by the exchange of a light vector boson. The dark fermions are produced by proton-…
Constraining CP-violating Higgs Sectors at the LHC using gluon fusion
Matthew J. Dolan, Philip Harris, Martin Jankowiak +1
We investigate the constraints that the LHC can set on a 126 GeV Higgs boson that is an admixture of CP eigenstates. Traditional analyses rely on Higgs couplings to massive vector…
Resolving the Higgs-Gluon Coupling with Jets
Malte Buschmann, Christoph Englert, Dorival Goncalves +2
In the Standard Model the Higgs coupling to gluons is almost entirely induced by top quark loops. We derive the logarithmic structure of Higgs production in association with two je…
Les Houches 2013: Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, R. Contino, B. Fuks +87
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 3--21 June, 2013). Our report includes new computatio…
Boosted Higgs Shapes
Matthias Schlaffer, Michael Spannowsky, Michihisa Takeuchi +2
The inclusive Higgs production rate through gluon fusion has been measured to be in agreement with the Standard Model (SM). We show that even if the inclusive Higgs production rate…
Limitations and Opportunities of Off-Shell Coupling Measurements
Christoph Englert, Michael Spannowsky
Indirect constraints on the total Higgs width from correlating Higgs signal strengths with cross section measurements in the off-shell region for producti…
Release Note - VBFNLO 2.7.0
J. Baglio, J. Bellm, F. Campanario +11
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 as well as QCD-induced s…
Standard Model Higgs boson pair production in the final state
Danilo Enoque Ferreira de Lima, Andreas Papaefstathiou, Michael Spannowsky
Measuring the Higgs boson couplings as precisely as possible is one of the major goals of the High Luminosity LHC. We show that the final state in Higgs boso…
Measuring collinear W emissions inside jets
Frank Krauss, Petar Petrov, Marek Schoenherr +1
Single and multiple emission of electroweak gauge bosons and in particular of W bosons is discussed in the parton shower language. Algorithms and observables for the reconstruction…
Reconstructing singly produced top partners in decays to
Nicolas Gutierrez Ortiz, James Ferrando, Deepak Kar +1
Fermionic top partners are a feature of many models of physics beyond the Standard Model. We propose a search strategy for single production of top partners focussing specifically…
Constraining new coloured matter from the ratio of 3- to 2-jets cross sections at the LHC
Diego Becciolini, Marc Gillioz, Marco Nardecchia +2
The Large Hadron Collider experiments are probing the evolution of the strong coupling up to the TeV scale. We show how the ratio of 3- to 2-jets cross sections is affected b…
Finding physics signals with event deconstruction
Davison E. Soper, Michael Spannowsky
We develop a matrix element based reconstruction method called event deconstruction. The method uses information from the hard matrix element and a parton shower to assign probabil…
Non-standard top substructure
Christoph Englert, Dorival Goncalves, Michael Spannowsky
The top quark, being the heaviest particle of the Standard Model, is a prime candidate of where physics beyond the SM might currently hide before our eyes. There are many natural e…
Extended gamma-ray emission from Coy Dark Matter
Celine Boehm, Matthew J. Dolan, Christopher McCabe +2
We show that it is possible for WIMP dark matter to produce a large signal in indirect dark matter searches without producing signals elsewhere. We illustrate our point by fitting…
