We show that a gravitational interaction between the derivative of the Ricci scalar curvature and the baryon-number current dynamically breaks CPT in an expanding Universe and, combined with baryon-number-violating interactions, can drive the Universe towards an equilibrium baryon asymmetry that is observationally acceptable.

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 o...

Predictions of unknown heavy baryon masses based on an expansion in 1/mQ, 1/Nc and SU(3) breaking are updated to take into account a recent measurement of the Σc mass. Values are given for the two remaining unknown charm baryon masses Ξc and Ω ∗ c and the seven unknown bottom baryon masses Ξb, Σb, Ξ ′ b, Ωb, Σ ∗ b , Ξ ∗ b and Ω ∗ b . The spectrum of baryons containing a single charm or bottom q...
