1. Probing new electroweak states via precision measurements at the LHC and future colliders / Luzio, Luca ; Gröber, Ramona ; Panico, Giuliano
Several new physics scenarios, motivated e.g. [...]

2. Analytical Method for Next-to-Leading-Order QCD Corrections to Double-Higgs Production / Bonciani, Roberto ; Degrassi, Giuseppe ; Giardino, Pier Paolo ; Gröber, Ramona
We propose a new method to calculate analytically higher-order perturbative corrections and we apply it to the calculation of the two-loop virtual corrections to Higgs pair production through gluon fusion. [...]

3. Searches for vector-like quarks at future colliders and implications for composite Higgs models with dark matter / Chala, Mikael ; Gröber, Ramona ; Spannowsky, Michael
Many composite Higgs models predict the existence of vector-like quarks with masses outside the reach of the LHC, e.g. [...]

4. Reconstruction of top-quark mass effects in Higgs pair production and other gluon-fusion processes / Gröber, Ramona ; Maier, Andreas ; Rauh, Thomas
We propose a novel method for the treatment of top-quark mass effects in the production of H (∗) , HH , HZ and ZZ final states in gluon fusion. [...]

5. Maxi-sizing the trilinear Higgs self-coupling: how large could it be? / Di Luzio, Luca ; Gröber, Ramona ; Spannowsky, Michael
In order to answer the question on how much the trilinear Higgs self-coupling could deviate from its Standard Model value in weakly coupled models, we study both theoretical and phenomenological constraints. [...]

6. On the two-loop virtual QCD corrections to Higgs boson pair production in the standard model / Degrassi, Giuseppe ; Giardino, Pier Paolo ; Gröber, Ramona
We compute the next-to-leading order virtual QCD corrections to Higgs-pair production via gluon fusion. [...]

7. Accidental matter at the LHC / Luzio, Luca ; Gröber, Ramona ; Kamenik, Jernej ; Nardecchia, Marco
We classify weak-scale extensions of the Standard Model which automatically preserve its accidental and approximate symmetry structure at the renormalizable level and which are hence invisible to low-energy indirect probes. [...]

8. Light stop decays into Wbχ˜10 near the kinematic threshold / Gröber, Ramona ; Mühlleitner, Margarete ; Popenda, Eva ; Wlotzka, Alexander
We investigate the decays of the light stop in scenarios with the lightest neutralino χ˜10 being the lightest supersymmetric particle, including flavour-violating (FV) effects. [...]
