Study Suggests Standard Model Physics Could Explain Universe's Matter-Antimatter Asymmetry

A new theoretical study proposes that CP violation within the Standard Model, specifically from the CKM matrix, could be sufficient to explain baryogenesis, the origin of the universe's matter-antimatter asymmetry. This challenges a long-held assumption in physics. The model introduces a leptoquark field whose decays could generate the observed baryon asymmetry, offering a potential explanation for a fundamental cosmic mystery using known physics.
