Photon splitting constraint on Lorentz Invariance Violation from Crab Nebula spectrum
Konstantin Astapov, Dmitry Kirpichnikov, Petr Satunin
We calculate the decay width of the photon splitting into three photons in a model of quantum electrodynamics with broken Lorentz invariance. We show that this process can lead to…
Prospects of models with light sgoldstino in electron beam dump experiment at CERN SPS
K. O. Astapov, D. V. Kirpichnikov
We discuss phenomenology of light scalar sgoldstino in context of CERN electron beam dump experiment NA64. We calculate sgoldstino production rate for this experiment taking into a…
Decaying light particles in the SHiP experiment. III. Signal rate estimates for scalar and pseudoscalar sgoldstinos
K. O. Astapov, D. S. Gorbunov
For supersymmetric extensions of the Standard Model with light sgoldstinos - scalar and pseudoscalar superparthners of goldstino - we estimate the signal rate anticipated at the la…
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…
