Research

The research of the Working Group is focused on the R-parity violating “μ from ν” Supersymmetric Standard Model (μνSSM), proposed in the paper:

Proposal for a supersymmetric standard model

For brief reviews on the μνSSM, see:

- Searching for SUSY and decaying gravitino DM at the LHC and Fermi-LAT with the μνSSM
- The Seesaw mechanism in the μνSSM
- Phenomenology of a new supersymmetric standard model: The μνSSM

Among our current studies are:

Phenomenology at the LHC
- Searching for left sneutrino LSP at the LHC
- Novel signatures for vector-like quarks
- Probing the μνSSM with light scalars, pseudoscalars and neutralinos from the decay of a SM-like Higgs boson at the LHC
- Hunting physics beyond the standard model with unusual W± and Z decays
- Probing the μ from ν supersymmetric standard model with displaced multileptons from the decay of a Higgs boson at the LHC
- The Higgs sector of the μνSSM and collider physics

Neutrino Physics
- Neutrino Physics and Spontaneous CP Violation in the μνSSM

Parameter space and spectrum
- Analysis of the parameter space and spectrum of the μνSSM

Extensions of the μνSSM
- On a reinterpretation of the Higgs field in supersymmetry and a proposal for new quarks
- The μνSSM with an Extra U(1)

Dark Matter
- Search for sharp and smooth spectral signatures of μνSSM gravitino dark matter with Fermi-LAT
- Search for 100 MeV to 10 GeV gamma-ray lines in the Fermi-LAT data and implications for gravitino dark matter in the μνSSM
- CLUES on Fermi-LAT prospects for the extragalactic detection of μνSSM gravitino Dark Matter
- Gamma-ray detection from gravitino dark matter decay in the μνSSM

Baryon Asymmetry (studied by other authors)
- Electroweak Phase Transition in the μνSSM
- R-parity violation assisted thermal leptogenesis in the seesaw mechanism
