Abstract
The reason for baryon asymmetry in our universe has been an open question for many years. This note shows that the holographic principle requires a charged preon model underlying the Standard Model of particle physics and, in consequence, requires baryon asymmetry. The baryon asymmetry predicted by a specific charged preon model in our closed inflationary Friedmann universe is consistent with observations.

Summary
The reason for the dominance of matter over antimatter in our universe has been a relevant issue for years [1]. Several complicated mechanisms have been proposed to account for baryon asymmetry (matter dominance), but they all require new particles or phenomena that have not been observed. This note shows that the holographic principle [2] provides a simple mechanism requiring baryon asymmetry. The holographic principle, developed from black hole thermodynamics, says all physics at a given point is described by the finite number of bits of information on the particle horizon at the greatest distance from which a light signal could reach the point since the end of inflation. It is noted that the holographic principle states that events within the universe are specified by the information on the particle horizon, and the characteristics of the particle horizon at the time of baryogenesis are determined. The results are compared with observations and it is noted that a similar analysis requires a lepton asymmetry resulting in a positron excess in the universe
