Configuration and Benchmarking of Processes with K4GeneratorsConfig
Alan Price, Dirk Zerwas
The next generation of electron-positron colliders will require unprecedented precision in both theory and experiment. Sophisticated software frameworks are essential to evaluate d…
Focus topics for the ECFA study on Higgs / Top / EW factories
Jorge de Blas, Patrick Koppenburg, Jenny List +105
In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e…
SuSpect3: A C++ Code for the Supersymmetric and Higgs Particle Spectrum of the MSSM
Jean-Loic Kneur, Gilbert Moultaka, Michael Ughetto +2
We present the program SuSpect3 that calculates the masses and couplings of the Higgs and supersymmetric particles predicted by the Minimal Supersymmetric Standard Model (MSSM). Th…
The Higgs Boson Mass as Fundamental Parameter of the Minimal Supersymmetric Standard Model
Rima El-Kosseifi, Jean-Loic Kneur, Gilbert Moultaka +1
In the Minimal Supersymmetric Standard Model (MSSM) the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the MSSM the precisely meas…
The Global Higgs Picture at 27 TeV
Anke Biekötter, Dorival Gonçalves, Tilman Plehn +2
We estimate the reach of global Higgs analyses at a 27 TeV hadron collider in terms of Higgs couplings and in terms of a gauge-invariant effective Lagrangian, including invisible H…
Higgs Factories: Higgs-Strahlung versus W-Fusion
Remi Lafaye, Tilman Plehn, Michael Rauch +1
Higgs factories will be able to measure Higgs properties, and in particular Higgs couplings with high precision. In a follow-up to an earlier analysis we study the impact of the Hi…
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…
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…
Constraining Supersymmetry using the relic density and the Higgs boson
Sophie Henrot-Versillé, Rémi Lafaye, Tilman Plehn +5
Recent measurements by Planck, LHC experiments, and Xenon100 have significant impact on supersymmetric models and their parameters. We first illustrate the constraints in the mSUGR…
Measuring Higgs Couplings at a Linear Collider
Markus Klute, Remi Lafaye, Tilman Plehn +2
Higgs couplings can be measured at a linear collider with high precision. We estimate the uncertainties of such measurements, including theoretical errors. Based on these results w…
Measuring Higgs Couplings from LHC Data
Markus Klute, Remi Lafaye, Tilman Plehn +2
Following recent ATLAS and CMS publications we interpret the results of their Higgs searches in terms of Standard Model operators. For a Higgs mass of 125 GeV we determine several…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
LHC: Standard Higgs and Hidden Higgs
Christoph Englert, Tilman Plehn, Michael Rauch +2
Interpretations of Higgs searches critically involve production cross sections and decay probabilities for different analysis channels. Mixing effects can reduce production rates,…
Hadronically decaying color-adjoint scalars at the LHC
Steffen Schumann, Adrien Renaud, Dirk Zerwas
We study the phenomenology of the pair-production of scalar color-octet electroweak singlet states at the LHC. Such states appear in many extensions of the Standard Model. They can…
Exploring the Higgs portal
Christoph Englert, Tilman Plehn, Dirk Zerwas +1
We study the Higgs portal from the Standard-Model to a hidden sector and examine which elements of the extended theory can be discovered and explored at the LHC. Our model includes…
Measuring Supersymmetry
Dirk Zerwas
Supersymmetry is an attractive extension of the standard model of particle physics. It associates to every bosonic degree of freedom a fermionic one and vice versa. Supersymmetry u…
Measuring Hidden Higgs and Strongly-Interacting Higgs Scenarios
Sebastian Bock, Remi Lafaye, Tilman Plehn +3
Higgs couplings can be affected by physics beyond the Standard Model. We study modifications through interactions with a hidden sector and in specific composite Higgs models access…
Measuring Unification
Claire Adam, Jean-Loic Kneur, Remi Lafaye +3
If supersymmetry is observed at the LHC its model parameters can be measured at the electroweak scale. We discuss the expected precision on the parameter determination, including a…
Stop Reconstruction with Tagged Tops
Tilman Plehn, Michael Spannowsky, Michihisa Takeuchi +1
At the LHC combinatorics make it unlikely that we will be able to observe stop pair production with a decay to a semi-leptonic top pair and missing energy for generic supersymmetri…
The Hunt for New Physics at the Large Hadron Collider
P. Nath, B. D. Nelson, H. Davoudiasl +84
The Large Hadron Collider presents an unprecedented opportunity to probe the realm of new physics in the TeV region and shed light on some of the core unresolved issues of particle…
Extracting the fundamental parameters
Dirk Zerwas
If supersymmetry is discovered at the LHC, the extraction of the fundamental parameters will be a formidable task. In such a system where measurements depend on different combinati…
CP Studies and Non-Standard Higgs Physics
S. Kraml, E. Accomando, A. G. Akeroyd +163
There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mi…
Physics Interplay of the LHC and the ILC
LC Study Group, G. Weiglein, T. Barklow +120
Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations…
