New physics from atmosphere: light sgoldstino case
S. V. Demidov
In a supersymmetric model with low scale supersymmetry breaking light sgoldstinos can appear in decays of mesons abundantly produced in atmospheric showers. We obtain bounds on par…
Numerical study of multiparticle scattering in theory
S. V. Demidov, B. R. Farkhtdinov
We study numerically classical collisions of waves in theory. These processes correspond to multiparticle scattering in the semiclassical regime. Parametrizing initial and f…
Semiclassical description of soliton-antisoliton pair production in particle collisions
S. V. Demidov, D. G. Levkov
We develop a consistent semiclassical method to calculate the probability of topological soliton-antisoliton pair production in collisions of elementary particles. In our method on…
Nucleon-decay-like signatures of Hylogenesis
S. V. Demidov, D. S. Gorbunov
We consider nucleon-decay-like signatures of the hylogenesis, a variant of the antibaryonic dark matter model. For the interaction between visible and dark matter sectors through t…
Soliton pair creation in classical wave scattering
S. V. Demidov, D. G. Levkov
We study classical production of soliton-antisoliton pairs from colliding wave packets in (1+1)-dimensional scalar field model. Wave packets represent multiparticle states in quant…
Non-minimal Split Supersymmetry
S. V. Demidov, D. S. Gorbunov
We present an extension of the minimal split supersymmetry model, which is capable of explaining the baryon asymmetry of the Universe. Instead of MSSM we start from NMSSM and split…
