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 ingredients. We show that for neutralinos with a significant singlino component the galactic center excess can be linked to invisible decays of the Standard-Model-like Higgs at the LHC. We find predictions for invisible Higgs branching ratios in excess of 50 percent, easily accessible at the LHC. Constraining the…

Global fits for new physics at the LHC and beyond
We study physics beyond the Standard Model with state–of–the–art global fits of both UV-complete models like supersymmetry and the more general effective field theories (EFTs). The gamma-ray excess
The inert doublet model in the light of Fermi-LAT gamma-ray data: a global fit analysis
We perform a global fit within the inert doublet model taking into account experimental observables from colliders, direct and indirect dark matter searches and theoretical constraints. In
Spin-dependent constraints on blind spots for thermal singlino-higgsino dark matter with(out) light singlets
A bstractThe LUX experiment has recently set very strong constraints on spin-independent interactions of WIMP with nuclei. These null results can be accommodated in NMSSM provided that the effective
Precise predictions for V+2 jet backgrounds in searches for invisible Higgs decays
We present next-to-leading order QCD and electroweak (EW) theory predictions for V +2 jet production, with V = Z, W ± , considering both the QCD and EW production modes and their interference. We
Light neutral CP-even Higgs boson within Next-to-Minimal Supersymmetric Standard model (NMSSM) at the Large Hadron electron Collider (LHeC)
We analyze the prospects of observing the light CP-even neutral Higgs bosons ($h_1$) in their decays into $b \bar b$ quarks, in the neutral and charged current production processes $e h_1 q$ and $\nu
The Higgs boson mass as fundamental parameter of the minimal supersymmetric standard model
In the Minimal Supersymmetric Standard Model (MSSM) the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the $$m_h$$ m h MSSM the precisely measured
Yet Another Introduction to Dark Matter
Dark matter is, arguably, the most widely discussed topic in contemporary particle physics. Written in the language of particle physics and quantum field theory, these notes focus on a set of
Model-independent analysis of the DAMPE excess
A bstractThe Dark Matter Particle Explorer (DAMPE) recently released measurements of the electron spectrum with a hint of a narrow peak at about 1.4 TeV. We investigate dark matter (DM) models that
