"Primordial nucleosynthesis as a probe of possible deviationof fundamental
physical constants"
Influence of coupling constant deviations from their current
values on the abundances of
4He, 2D+3He, and 7Li
nuclei produced during the primordial nucleosynthesis is studied
taking into account the possibility of simultaneous variations
of the gravitational and electroweak constants. It is shown
that contemporary observational data allow for these constants
to vary within a large region of the parameter space.
The constraints on these variations differ considerably
from ones published early.
