Conversion of protons to positrons by a black hole
A. D. Dolgov, A. S. Rudenko
The conversion of protons to positrons at the horizon of a black hole (BH) is considered. It is shown that the process may efficiently proceed for BHs with masses in the range $\si…

Gravitational four-fermion interaction and dynamics of the early Universe
I. B. Khriplovich, A. S. Rudenko
If torsion exists, it generates gravitational four-fermion interaction (GFFI), essential on the Planck scale. We analyze the influence of this interaction on the Friedmann-Lemaitre…

Cosmology constrains gravitational four-fermion interaction
I. B. Khriplovich, A. S. Rudenko
If torsion exists, it generates gravitational four-fermion interaction (GFFI). This interaction gets dominating on the Planck scale. If one confines to the regular, axial-axial par…
