Applying EFT to Higgs Pair Production in Universal Extra Dimensions
Lisa Edelhaeuser, Alexander Knochel, Thomas Steeger
We investigate single Higgs and Higgs pair production at the LHC in models of Universal Extra Dimensions. After calculating the relevant cross sections, we use the UED model as a t…
Observing nonstandard and through the third generation and Higgs lens
Lisa Edelhäuser, Alexander Knochel
We reinterpret , and Higgs searches at the LHC in terms of a model with nonuniversal couplings to fermions in order to gauge how well these searches can be applied ou…
Vices and Virtues of Higgs EFTs at Large Energy
Anke Biekoetter, Alexander Knochel, Michael Kraemer +2
We study constraints on new physics from Higgs production at the LHC in the context of an effective field theory (EFT), focusing on Higgs searches in () associated prod…
What can the Higgs tell us about UV physics?
Alexander K Knochel
After the discovery of a Higgs-like boson with a mass of m~125 GeV at the LHC, we can now attempt to draw conclusions about physics beyond the Standard Model. I argue that there ar…
NMSSM with Lopsided Gauge Mediation
Ivan Donkin, Alexander K. Knochel
We study a gauge mediated supersymmetry breaking version of the NMSSM in which the soft m_{H_u}^2 and m_{H_d}^2 masses receive extra contributions due to the presence of direct cou…
The Price of Neutrino Superluminality continues to rise
Arthur Hebecker, Alexander Knochel
We revisit the model building challenges that one faces when trying to reconcile the OPERA claim of neutrino superluminality with other observational constraints. The severity of t…
Theoretical constraints on new generations with and without Quarks or Neutrinos
Alexander Knochel, Christof Wetterich
We consider large classes of chiral extensions of the Standard Model, including new quark generations that do not involve additional neutrinos as well as lepton generations without…
Discriminating 4D supersymmetry from its 5D warped version
Charles Bouchart, Alexander Knochel, Grégory Moreau
In the scenario where only superpartners were produced at the Large Hadron Collider, how one could determine whether the supersymmetric model pointed out is 4-dimensional or higher…
Observing Higgsless LSPs at the LHC
Alexander Knochel
We explore the LHC phenomenology of the dark matter candidate arising from the extension of warped Higgsless models. In particular, we consider a model of warped supersymmetry in t…
An Exceptional SSM from E6 Orbifold GUTs with intermediate LR symmetry
Felix Braam, Alexander Knochel, Juergen Reuter
We propose a class of E6-based local orbifold Grand Unified Theories (GUTs) which yield an exceptional supersymmetric standard model as their low energy theory including leptoquark…
Production of Dark Matter in Warped Higgsless Models with Composite Sector Supersymmetry
Alexander Knochel, Thorsten Ohl
We explore the LHC phenomenology of an extension of warped higgsless models. The model is supersymmetric in the bulk and on the IR brane as introduced in [arXiv:0805.1379], corresp…
Supersymmetric Extensions and Dark Matter in Models of Warped Higgsless EWSB
Alexander Knochel, Thorsten Ohl
We introduce a minimal supersymmetric extension of a higgsless model for electroweak symmetry breaking in a warped extra dimension. In contrast to the non supersymmetric version, o…
