Sgoldstino-Higgs mixing in models with low-scale supersymmetry breaking
K. O. Astapov, S. V. Demidov
We consider a supersymmetric extension of the Standard Model with low-scale supersymmetry breaking. Besides usual superpartners it contains additional chiral goldstino supermultipl…

Collider signatures of Hylogenesis
S. V. Demidov, D. S. Gorbunov, D. V. Kirpichnikov
We consider collider signatures of the hylogenesis --- a variant of antibaryonic dark matter model. We obtain bounds on the model parameters from results of the first LHC run. Also…

SUSY in the sky or a keV signature of sub-GeV gravitino dark matter
S. V. Demidov, D. S. Gorbunov
We point out that recently discovered 3.5 keV line in X-ray spectra from various galaxy clusters and the Andromeda galaxy can be naturally explained by physics of a sector responsi…
