Open AccessRecasting direct detection limits within micrOMEGAs and implication for non-standard dark matter scenarios
Direct detection experiments obtain 90% upper limits on the elastic scattering cross sections of dark matter with nucleons assuming point-like interactions and standard astrophysical and cosmological parameter...

Open AccessLHC-friendly minimal freeze-in models
We propose simple freeze-in models where the observed dark matter abundance is explained via the decay of an electrically charged and/or coloured parent particle into Feebly Interacting Massive Particles (FIMP...

Open AccessStatus and prospects of the nMSSM after LHC Run-1
The new minimal supersymmetric standard model (nMSSM), a variant of the general next to minimal supersymmetric standard model (NMSSM) without Z 3 symmetry, features a naturally lig...

Open AccessProbing U(1) extensions of the MSSM at the LHC Run I and in dark matter searches
The U(1) extended supersymmetric standard model (UMSSM) can accommodate a Higgs boson at 125 GeV without relying on large corrections from the top/stop sector. After imposing LHC results on the Higgs sector, on B

Open AccessTop polarization in stop production at the LHC
We survey the expected polarization of the top produced in the decay of a scalar top quark, \( \widetilde{t}\to t\widetilde{\chi}_i^0,i=1-2 \) . The phenomenology is quite interesting...

Open AccessHiggs couplings at the end of 2012
Performing a fit to all publicly available data, we analyze the extent to which the latest results from the LHC and Tevatron constrain the couplings of the Higgs boson like state at ~ 125 GeV. To this end we a...

Article
Supersymmetry parameter analysis: SPA convention and project
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corr...

Bosonic quartic couplings at LEP2
We list the set of \(\mathcal{C}\) and \(\mathcal{P}\) conserving anomalous quartic vector bosons self-couplings which can be tested at LEP2 th...

Z radiation off stops at a linear collider
We calculate \(e^+e^-\to \tilde t_1 \tilde t_1 Z\) at a linear collider. For large splitting between the two stops, the cross section is sensitive to the value of ...

Associated stop-Higgs production at a linear collider and extraction of stop parameters
We calculate stop-stop-Higgs production at a linear collider. Combining the measurements from the pair production of the lightest stop and that of the mass of the Higgs, we show how, in a scenario where only ...
