We demonstrate that this mechanism occurs quite naturally in intersecting-brane constructions of the Standard Model, and show that it solves some of the theoretical difficulties faced in matching baryogenesis to experimental bounds. We illustrate with a specific example model. We also discuss the possible signals at the LHC.14 pages, LaTeX. References addedHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
