Is gravitino still a warm dark matter candidate?
D. Gorbunov, A. Khmelnitsky, V. Rubakov
We make use of the phase space density approach to discuss gravitino as a warm dark matter candidate. Barring fine tuning between the reheat temperature in the Universe and superpa…
Large and infinite extra dimensions
V. A. Rubakov
The emphasis in the developmet of theories with more than three spatial dimensions has recently shifted towards ``brane world'' picture, which assumes that ordinary matter (with po…
Kaon Physics with Light Sgoldstinos and Parity Conservation
D. S. Gorbunov, V. A. Rubakov
Superpartners of goldstino -- scalar and pseudoscalar sgoldstinos -- interact weakly with ordinary particles. One or both of them may be light. We consider a class of supersymmetri…
Is the electric charge conserved in brane world?
S. L. Dubovsky, V. A. Rubakov, P. G. Tinyakov
We discuss whether electric charge conservation may not hold in four-dimensional world in models with infinite extra dimensions, i.e., whether escape of charged particles from our…
Relaxation of the cosmological constant at inflation?
V. A. Rubakov
We suggest that the cosmological constant has been relaxed to its present, very small value during the inflationary stage of the evolution of the Universe. This requires relatively…
