Multiscalar-metric gravity: merging gravity, dark energy and dark matter
Yu. F. Pirogov, O. V. Zenin
The status of a modification of General Relativity (GR) -- Spontaneously Broken Relativity (SBR) -- for merging gravity, dark energy (DE) and dark matter (DM) is presented. The mod…

Quartet-metric gravity and scalar graviton dark holes: supplements
Yu. F. Pirogov, O. V. Zenin
This note includes results of a study of stationary spherically symmetric ``dark holes'', objects merging central black holes and peripheral scalar graviton dark haloes arising in…

Two-loop renormalization group restrictions on the standard model and the fourth chiral family
Yu. F. Pirogov, O. V. Zenin
In the framework of the two-loop renormalization group, the global profile of the Standard Model (SM) in its full parameter space is investigated up to the scale of the gauge singu…
