Baryon number of the Universe as a result of extra space dynamics. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics Volume 726, Issue 4-5, 2013, Pages 554-558

Origin of baryon asymmetry is studied in the framework of extra dimensional approach. Baryon excess production and the symmetrization of extra-space are performed simultaneously. Baryon number is conserved long after the inflationary stage when the U(1) symmetry is achieved.
