No Miracle in Gravity Portals
Fedor Bezrukov, Sergey Demidov, Dmitry Gorbunov
The idea of dark matter particles coupled only gravitationally is minimalist yet viable. Assuming an additional -breaking linear coupling of scalar curvature to the dark matte…
Sgoldstino signature in , and spectra at the LHC
S. Demidov, D. Gorbunov, E. Kriukova
In a supersymmetric extension of the Standard Model of particle physics (SM) with low scale of supersymmetry breaking, sgoldstino of (sub)TeV mass can be observed at the Large Hadr…
Constraints on hidden photons produced in nuclear reactors
Mikhail Danilov, Sergey Demidov, Dmitry Gorbunov
New light vector particles - hidden photons - are present in many extensions of the Standard Model of particle physics. They can be produced in nuclear reactors and registered by n…
Low scale supersymmetry at the LHC with jet and missing energy signature
S. V. Demidov, I. V. Sobolev
If supersymmetry is broken at TeV scale, particles from sector responsible for supersymmetry breaking - goldstino and sgoldstinos - can reveal themselves already at the LHC experim…
More about sgoldstino interpretation of HyperCP events
S. V. Demidov, D. S. Gorbunov
We further discuss possible sgoldstino interpretation of the observation, reported by the HyperCP collaboration, of three Σ^+\to pμ^+μ^- decay events with dimuon invariant mass 214…
