Induced gravity and gauge interactions revisited
It has been shown that the primary, old-fashioned idea of Sakharov's induced
gravity and gauge interactions, in the "one-loop dominance" version, works
astonishingly well yielding phenomenologically reasonable results. As a
byproduct, the issue of the role of the UV cutoff in the context of the induced
gravity has been reexamined (an idea of self-cutoff induced gravity). As an
additional check, the black hole entropy has been used in the place of the
action. Finally, it has been explicitly shown that the induced coupling
constants of gauge interactions of the standard model assume qualitatively
realistic values.Comment: 15 pages, 2 figures (including 1 table); improved version - fina
The Size of the Weak Bosons
We study the hypothesis that weak bosons are composite systems, which have a
size of the order of 10^{-17} cm. The electromagnetic selfenergies of the weak
bosons lead to specific departures from the standard electroweak model, in
agreement with observation. Above the energy of 1 TeV the standard electroweak
model breaks down completely.Comment: 8 page
