Scientific paper

Some cosmological consequences of baryon nonconservation in new grand unified gauge theories are calculated in nonuniform space-times. The possibility of explaining the observed baryon asymmetry is examined in an anisotropically expanding universe. Upper and lower bounds on the x-boson mass are derived in terms of fundamental constants and the isotropization time. If the baryon asymmetry is to be determined by the asymmetric boson decay with no arbitrary contribution from the pre-Planck era, then the universe must have been isotropic and radiation dominated by about 10 to the -37th sec.
