Long-lived higgsinos as probes of gravitino dark matter at the LHC
S. Bobrovskyi, J. Hajer, S. Rydbeck
We investigate the LHC sensitivity to supersymmetric models with light higgsinos, small R-parity breaking and gravitino dark matter. The limits on decaying gravitino dark matter fr…
Searching for light higgsinos with b-jets and missing leptons
S. Bobrovskyi, F. Brümmer, W. Buchmuller +1
A recently proposed class of supersymmetric models predicts rather light and nearly mass-degenerate higgsinos, while the other superparticles are significantly heavier. In this pap…
Quasi-stable neutralinos at the LHC
S. Bobrovskyi, W. Buchmuller, J. Hajer +1
We study supersymmetric extensions of the Standard Model with small R-parity and lepton number violating couplings which are naturally consistent with primordial nucleosynthesis, t…
Broken R-Parity in the Sky and at the LHC
Sergei Bobrovskyi, Wilfried Buchmuller, Jan Hajer +1
Supersymmetric extensions of the Standard Model with small R-parity and lepton number violating couplings are naturally consistent with primordial nucleosynthesis, thermal leptogen…
