Results from TopFitter
Andy Buckley, Christoph Englert, James Ferrando +5
We discuss a global fit of top quark BSM couplings, phrased in the model-independent language of higher-dimensional effective operators, to the currently available data from the LH…
Perturbative Higgs CP violation, unitarity and phenomenology
Christoph Englert, Karl Nordström, Kazuki Sakurai +1
Perturbative probability conservation provides a strong constraint on the presence of new interactions of the Higgs boson. In this work we consider CP violating Higgs interactions…
Same-sign W pair production in composite Higgs models
Christoph Englert, Peter Schichtel, Michael Spannowsky
Non-minimal composite Higgs scenarios can contain exotic Higgs states which, if getting observed at the Large Hadron Collider, will help to constrain the underlying UV structure of…
Getting Stuck: Using Monosignatures to Test Highly Ionizing Particles
Christoph Englert, Joerg Jaeckel
In this paper we argue that monojet and monophoton searches can be a sensitive test of very highly ionizing particles such as particles with charges and more general…
Giving top quark effective operators a boost
Christoph Englert, Karl Nordstrom, Liam Moore +1
We investigate the prospects to systematically improve generic effective field theory-based searches for new physics in the top sector during LHC run 2 as well as the high luminosi…
Physics at a 100 TeV pp collider: Higgs and EW symmetry breaking studies
R. Contino, D. Curtin, A. Katz +72
This report summarises the physics opportunities for the study of Higgs bosons and the dynamics of electroweak symmetry breaking at the 100 TeV pp collider.
Towards resolving strongly-interacting dark sectors at colliders
Christoph Englert, Karl Nordström, Michael Spannowsky
Dark sectors with strong interactions have received considerable interest. Assuming the existence of a minimally coupled dark sector which runs to strong interactions in the infrar…
Les Houches 2015: Physics at TeV colliders - new physics working group report
G. Brooijmans, C. Delaunay, A. Delgado +78
We present the activities of the 'New Physics' working group for the 'Physics at TeV Colliders' workshop (Les Houches, France, 1-19 June, 2015). Our report includes new physics stu…
S-Channel Dark Matter Simplified Models and Unitarity
Christoph Englert, Matthew McCullough, Michael Spannowsky
The ultraviolet structure of -channel mediator dark matter simplified models at hadron colliders is considered. In terms of commonly studied -channel mediator simplified mode…
LHC Signatures Of Scalar Dark Energy
Philippe Brax, Clare Burrage, Christoph Englert +1
Scalar dark energy fields that couple to the Standard Model can give rise to observable signatures at the LHC. In this work we show that missing energy and mono-jet searc…
New physics and signal-background interference in associated production
Christoph Englert, Rogerio Rosenfeld, Michael Spannowsky +1
We re-investigate electroweak signal-background interference in associated Higgs production via gluon fusion in the presence of new physics in the top-Higgs sector. Considering the…
